How To Write A Consulting Case Study: Guide, Template, & Examples

When you deliver a successful project, do you publish a consulting case study about it?

A consulting case study is a short story about a successful project that explains…

• The problem your client was dealing with before hiring you;
• your expertise and process for solving that problem;
• and the results your expertise and process created for the client and their business.

In my experience, our consulting case studies are among the most powerful pieces of content we publish. They’re a big reason why people are comfortable signing up for our Clarity Coaching Program .

Because our case studies prove our program helps our clients get results.

I can say that our coaching program is the best on the market until I’m blue in the face.

But it’s much more powerful for consultants to see the results others have experienced for themselves: through our case studies and testimonials.

If you don’t have something of value on your website like a case study — something that actually shows you can achieve results for your clients — then your website will only serve as “confirmational marketing.”

It will confirm what people hear about you. But it won’t help you generate interest and leads.

So, if you want to shift your website beyond mere confirmational marketing to an asset that helps you generate leads and conversions, consider writing consulting case studies using the method below.

In this article, you’ll learn how to write compelling case studies that help you win more consulting clients.

Ready? Let’s dive in…

Your case study is proof that not only can you talk the talk, but you can also walk the walk.

What Is A Consulting Case Study?

When a potential client is deciding on whether they will hire you or not, a big question in their mind is…

“Can this person or company really do what they say they can for my business?”

There are many forms of thought leadership you can use to prove you can deliver results.

The consulting case study is one of them.

A case study, in the context of consulting, is typically a written document that describes…

• the problem a client was facing,
• the actions you took to solve that problem,
• and the outcomes it created for your client.

You write case studies to demonstrate the results and value you created for a past or current client.

What makes them so effective as marketing material?

• They are relatively easy to put together (especially when you use our template below).
• Your potential clients enjoy reading them.
• And they are a highly effective way to demonstrate your authority and expertise in your field.

Next, I’ll walk you through how to write a consulting case study.

In our program, one of the things we teach consultants is how to better understand their clients’ problems and articulate their ability to solve those problems in a way that will attract new clients.

How To Write A Consulting Case Study

Here are the steps to writing your consulting case study. You can follow along with our consulting case study template .

1. Get Permission From The Client

You shouldn’t write a case study that names your client without their permission.

So, before you start writing it, ask them if they’d be OK with you publishing a case study about the project.

Now, I’m not a lawyer, and nothing in this article or anything I write is legal or financial advice. But here’s what we’ve found, through running consulting businesses for over two decades, often works best:

A question we often receive from consultants is “What if I can’t use the name of my client or the company I worked with?” Generally, this isn’t an issue. If your contract says you can’t use the client’s company name, or the client says “No” to your request, all is not lost.

What tends to work extremely well is still writing the case study, but without using the client’s name. Instead, describe the client.

For example, let’s say your client is the automaker Mazda. If you can’t use their name, consider “Working with a top 20 global automaker…”

This gives prospective buyers a good idea of the caliber and type of company you worked with.

When you ask your client for their permission to create a case study that features them, you’ll generally find that 9 times out of 10 they won’t have a problem with you doing so, but make sure you ask before publishing.

2. Introduce The Client’s Business

Once you’ve gotten permission from the client, you’ll begin writing your case study. Follow along using our template .

The first section is the introduction. Set the stage here by introducing your client, their business, and their industry.

This section gives context to the case study. Ideally, your ideal client is intrigued by being in a similar industry or situation as the client in your case study.

3. Describe The Problem Or Challenge

In this section, you outline the problem your client was facing.

Be as specific as you can be.

Simply saying they had marketing issues or a problem with their PR is not enough.

The more detail you include the clearer the picture will become and the more effective your case study copywriting will be.

If your ideal client reads this and has a similar problem as the client in the case study, you can guarantee that their eyes will be glued to the screen, salivating to learn how you solved it.

4. Summarize Your Action Steps

Now that you’ve described the problem your client was up against, you’ll explain what you did to help solve the problem.

In this section, break down each part of the process you used or the steps you took to solve it.

The reader should get the sense that you have a process or system capable of solving the problem and getting results.

This is where you get to demonstrate your know-how and expertise. Get as technical as you can. Show your reader “Hey, this is how I can get YOU results too.”

5. Share The Results

It’s time to demonstrate results.

Write the results that were achieved and how they impacted the business/organization/person.

In many cases, the outcome isn’t just dollars and cents — it can also be less tangible value.

Are they less stressed? Do they have more free time? Are they finding more meaning and enjoyment in their work?

Mention if you’re continuing to work with this client through a retainer . If you’re not, describe how the results will impact their business in the future.

This is also a great place to include a quote or testimonial from your client.

The “Results” section is key because it shows prospective clients that you’ve solved the problems they are facing and have delivered the actual results that they likely desire.

6. Write A Call To Action

At the end of the case study, you should always include a sentence or two inviting the ideal client to reach out.

They’ve just read about the problems you can solve, how you solve them, and the results you can create.

They are primed and ready to reach out to inquire about how you can do it for them.

But if you don’t have a direct call to action for them to do that, many of them will leave without taking action.

So, write a direct, clear call to action that takes them to a page where it’s easy to book a consultation with you or where you provide your contact information.

7. Share It

Marketing for consultants is all about providing value to your ideal clients, being known for something specific, and positioning yourself as an expert and authority that your ideal clients want to work with. So, whenever you publish a piece of valuable content like a case study, your mission is to get as many eyes on the case study as possible.

The best place to publish your case study is on your website or blog.

You can also submit case studies to industry publications. These are a great way to spread the word about you and your client’s business.

Make sure to also share your case study on all social media platforms where your ideal clients hang out online. For consultants, that means LinkedIn.

Work your “marketing muscle” by actively promoting your case study, and you’ll reap the rewards of this powerful piece of authority-building content.

Writing case studies for your consulting business not only helps you land new clients, but it’s also a great way for you to review past projects.

Doing this helps you to find what worked and what didn’t.

And you’ll continue to learn from your experiences and implement your best practices into your next consulting project.

This is a great outline and I found it quite helpful. Thanks.

Shana – glad you found this post helpful!

I have used case studies to get new clients and you're right, They work.

Jay – thanks for sharing. I've worked with many clients to implement case studies and have used them in several businesses and have always found them to be great at supporting proof and establishing authority and credibility.

Dumb question: guess you can't charge if you're doing a case study, huh?

Terri – No such thing as a dumb question where I come from. Always good to ask.

You definitely can charge for case studies. Michael Stelzner has a lot more information on writing white papers (and case studies) as projects.

This post was really aimed at using case studies to win more business and attract clients. But you can definitely offer this service to companies and they'll pay handsomely for it.

That was a great question!

Hello,I am really glad I stumbled upon your consulting site. This outline is very helpful and I love the e-mails I recieve as well Thanks!

Happy to hear that

This is a great site for consultants – great information for the team to share with consultants that reach out to us. Thank you!

Thanks Deborah

It is a good steps if we know how we start and control our working.

All I wanted to know about putting together a case study I have got. Thanks so much.

I have used your outline today to write one case. Thank you for sharing.

Hi – This is a great piece, and covers all the core elements of a case study with impact.

Couple of extra points…

1. it’s really powerful to provide a mix of qualitative and quantitative results where possible e.g. ‘we saved the client $500 per month and feedback tells us morale improved’

2. We are seeing more and more consultancies include images and video in their case studies. This obviously depends on the context, so while it’s not necessarily appropriate within the confines of a bid, it is definitely something to think about for those case studies that you want to publish online or in a marketing brochure.

1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots. You might need to pass these either before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

Let's dive right in and find out!

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. Where are case interviews in the consulting selection process?

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews (although this happens less frequently now). Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start . For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as a case interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself! Also we need to note that the general timeline of an application can differ depending on a series of factors, including which position you apply, your background, and the office you are applying to. For example, an undergraduate applying for a Business Analyst position (the entry level job at McKinsey) will most likely be part of a recruitment cycle and as such have pretty fixed dates when they need to sit the pre-screening test, and have the first and second round interviews (see more on those below). Conversely, an experienced hire will most likely have a much greater choice of test and interview dates as well as more time at their disposal to prepare.

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.1.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.1.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live case interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases . We give some specific advice for online cases in section six. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.1.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.2. Differences between first and second round interviews

Despite case interviews in the first and second round following the same format, second/final round interviews will be significantly more intense . The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.3. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

Being concise and to the point is key in many areas, networking being one for them. For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

3. types of case interview.

While most case interviews share a similar structure, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

3.1. Different case objectives

A guiding thread throughout this article and our approach in general will be to treat each case as a self-contained problem and not try to pigeonhole it into a certain category. Having said that, there are of course similarities between cases and we can identify certain parameters and objectives.

Broadly speaking, cases can be divided into issue-based cases and strategic decision cases. In the former you will be asked to solve a certain issue, such as declining profits, or low productivity whereas in the latter you will be ask whether your client should or should not do something, such as enter a specific market or acquire another company. The chart below is a good breakdown of these different objectives:

3.2. How do interviewers craft cases

While interviewers will very likely be given a case bank to choose from by their company, a good number of them will also choose to adapt the cases they would currently be working on to a case interview setting. The difference is that the latter cases will be harder to pigeonhole and apply standard frameworks to, so a tailored approach will be paramount.

If you’ve applied for a specific practice or type of consulting - such as operational consulting, for example - it’s very likely that you will receive a case geared towards that particular area alongside a ‘generalist’ consulting case (however, if that’s the case, you will generally be notified). The other main distinction when it comes to case interviews is between interviewer-led and candidate-led.

3.3. Candidate-led cases

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms. From a structuring perspective, it’s easier to lose direction in a candidate-led case as there are no sign-posts along the way. As such, you need to come up with an approach that is both broad enough to cover all of the potential drivers in a case but also tailored enough to the problem you are asked to solve. It’s also up to you to figure out when you need to delve deeper into a certain branch of the case, brainstorm or ask for data. The following case from Bain is an excellent example on how to navigate a candidate-led case.

3.4. Interviewer-led cases

This type of case - employed most famously by McKinsey - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially. These cases are easier to follow as the interviewer will guide you in the right direction. However, this doesn’t mean you should pay less attention to structure and deliver a generic framework! Also, usually (but not always!) the first question will ask you to map your approach and is the equivalent of the structuring question in candidate-led cases. Sometimes, if you’re missing key elements, the interviewer might prompt you in the right direction - so make sure to take those prompts seriously as they are there to help you get back on track (ask for 30 seconds to think on the prompt and structure your approach). Other times - and this is a less fortunate scenario - the interviewer might say nothing and simply move on to the next question. This is why you should put just as much thought (if not more) into the framework you build for interviewer-led cases , as you may be penalized if you produce something too generic or that doesn’t encompass all the issues of the case.

3.5. Case and fit

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

3.5.1 Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

3.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions , focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article . However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

3.6. What is different in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run . Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and case interview blurs. Online cases don’t just reduce the number of candidates to case interview, but start directly replacing them.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “basic” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific case interview format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

3.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated case interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

4. How to solve cases with the Problem-Driven Structure?

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your case interviews.

To address this problem, the MyConsultingCoach team has synthesized a new approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case interview, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same (see the method in action in the video below)

Let's zoom in to see how our method actually works in more detail:

4.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

4.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

4.2.1 Issue trees

Issue trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

4.2.2 Hypothesis trees

Hypothesis trees are similar, the only difference being that rather than just trying to break up the issue into smaller issues you are assuming that the problem can be solved and you are formulating solutions.

In the example above, you would assume revenues can be increased by either increasing the average ticket price or the number of customers . You can then hypothesize that you can increase the average occupancy rate in three ways: align the schedule of short and long haul flights, run a promotion to boost occupancy in off-peak times, or offer early bird discounts.

4.2.3 Other structures:structured lists

Structured lists are simply subcategories of a problem into which you can fit similar elements. This McKinsey case answer starts off by identifying several buckets such as retailer response, competitor response, current capabilities and brand image and then proceeds to consider what could fit into these categories.

Buckets can be a good way to start the structure of a complex case but when using them it can be very difficult to be MECE and consistent, so you should always aim to then re-organize them into either an issue or a hypothesis tree.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues. Ultimately all these lists are methods to set out a logical hierachy among elements.

4.2.4 Structures in practice

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

4.2. Lead the analysis

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level and considering the 80/20 rule(see below), solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

4.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In a case interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

4.5. What if I get stuck?

Naturally with case interviews being difficult problems there may be times where you’re unsure what to do or which direction to take. The most common scenario is that you will get stuck midway through the case and there are essentially two things that you should do:

• 1. Go back to your structure
• 2. Ask the interviewer for clarification

Your structure should always be your best friend - after all, this is why you put so much thought and effort into it: if it’s MECE it will point you in the right direction. This may seem abstract but let’s take the very simple example of a profitability case interview: if you’ve started your analysis by segmenting profit into revenue minus costs and you’ve seen that the cost side of the analysis is leading you nowhere, you can be certain that the declining profit is due to a decline in revenue.

Similarly, when you’re stuck on the quantitative section of the case interview, make sure that your framework for calculations is set up correctly (you can confirm this with the interviewer) and see what it is you’re trying to solve for: for example if you’re trying to find what price the client should sell their new t-shirt in order to break even on their investment, you should realize that what you’re trying to find is the break even point, so you can start by calculating either the costs or the revenues. You have all the data for the costs side and you know they’re trying to sell 10.000 pairs so you can simply set up the equation with x being the price.

As we’ve emphasised on several occasions, your case interview will be a dialogue. As such, if you don’t know what to do next or don’t understand something, make sure to ask the interviewer (and as a general rule always follow their prompts as they are trying to help, not trick you). This is especially true for the quantitative questions, where you should really understand what data you’re looking at before you jump into any calculations. Ideally you should ask your questions before you take time to formulate your approach but don’t be afraid to ask for further clarification if you really can’t make sense of what’s going on. It’s always good to walk your interviewer through your approach before you start doing the calculations and it’s no mistake to make sure that you both have the same understanding of the data. For example when confronted with the chart below, you might ask what GW (in this case gigawatt) means from the get-go and ask to confirm the different metrics (i.e. whether 1 GW = 1000 megawatts). You will never be penalised for asking a question like that.

5. What to remember in case interviews

If you’re new to case cracking you might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking case interviews is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

5.1. An overall clear structure

You will probably hear this more than you care for but it is the most important thing to keep in mind as you start solving cases, as not only it is a key evaluation criterion but the greatest tool you will have at your disposal. The ability to build a clear structure in all aspects of the case inteview will be the difference between breezing through a complicated case and struggling at its every step. Let’s look a bit closer at the key areas where you should be structured!

5.1.1 Structured notes

Every case interview starts with a prompt, usually verbal, and as such you will have to take some notes. And here is where your foray into structure begins, as the notes you take should be clear, concise and structured in a way that will allow you to repeat the case back to the interviewer without writing down any unnecessary information.

This may sound very basic but you should absolutely not be dismissive about it: taking clear and organized notes will allow what we found helps is to have separate sections for:

• The case brief
• Follow-up questions and answers
• Numerical data
• Case structure (the most crucial part when solving the case)
• Any scrap work during the case (usually calculations)

When solving the case - or, as we call it here, in the Lead the analysis step, it is highly recommended to keep on feeding and integrating your structure, so that you never get lost. Maintaining a clear high level view is one of the most critical aspects in case interviews as it is a key skill in consulting: by constantly keeping track of where you are following your structure, you’ll never lose your focus on the end goal.

In the case of an interviewer-led case, you can also have separate sheets for each question (e.g. Question 1. What factors can we look at that drive profitability?). If you develop a system like this you’ll know exactly where to look for each point of data rather than rummage around in untidy notes. There are a couple more sections that you may have, depending on preference - we’ll get to these in the next sections.

5.1.2 Structured communication

There will be three main types of communication in cases:

• 1. Asking and answering questions
• 2. Walking the interviewer through your structure (either the case or calculation framework - we’ll get to that in a bit!)
• 3. Delivering your recommendation

Asking and answering questions will be the most common of these and the key thing to do before you speak is ask for some time to collect your thoughts and get organised. What you want to avoid is a ‘laundry list’ of questions or anything that sounds too much like a stream of consciousness.

Different systems work for different candidates but a sure-fire way of being organised is numbering your questions and answers. So rather than saying something like ‘I would like to ask about the business model, operational capacity and customer personas’ it’s much better to break it down and say something along the lines of ‘I’ve got three key questions. Firstly I would like to inquire into the business model of our client. Secondly I would like to ask about their operational capacity. Thirdly I would like to know more about the different customer personas they are serving’.

A similar principle should be applied when walking the interviewer through your structure, and this is especially true of online case interviews (more and more frequent now) when the interviewer can’t see your notes. Even if you have your branches or buckets clearly defined, you should still use a numbering system to make it obvious to the interviewer. So, for example, when asked to identify whether a company should make an acquisition, you might say ‘I would like to examine the following key areas. Firstly the financial aspects of this issue, secondly the synergies and thirdly the client’s expertise’

The recommendation should be delivered top-down (see section 4.4 for specifics) and should employ the same numbering principle. To do so in a speedy manner, you should circle or mark the key facts that you encounter throughout the case so you can easily pull them out at the end.

5.1.3 Structured framework

It’s very important that you have a systematic approach - or framework - for every case. Let’s get one thing straight: there is a difference between having a problem-solving framework for your case and trying to force a case into a predetermined framework. Doing the former is an absolute must , whilst doing the latter will most likely have you unceremoniously dismissed.

We have seen there are several ways of building a framework, from identifying several categories of issues (or ‘buckets’) to building an issue or hypothesis tree (which is the most efficient type of framework). For the purpose of organization, we recommend having a separate sheet for the framework of the case, or, if it’s too much to manage, you can have it on the same sheet as the initial case prompt. That way you’ll have all the details as well as your proposed solution in one place.

5.1.4 Structured calculations

Whether it’s interviewer or candidate-led, at some point in the case you will get a bunch of numerical data and you will have to perform some calculations (for the specifics of the math you’ll need on consulting interviews, have a look at our Consulting Math Guide ). Here’s where we urge you to take your time and not dive straight into calculating! And here’s why: while your numerical agility is sure to impress interviewers, what they’re actually looking for is your logic and the calculations you need to perform in order to solve the problem . So it’s ok if you make a small mistake, as long as you’re solving for the right thing.

As such, make it easy for them - and yourself. Before you start, write down in steps the calculations you need to perform. Here’s an example: let’s say you need to find out by how much profits will change if variable costs are reduced by 10%. Your approach should look something like:

• 1. Calculate current profits: Profits = Revenues - (Variable costs + Fixed costs)
• 2. Calculate the reduction in variable costs: Variable costs x 0.9
• 3. Calculate new profits: New profits = Revenues - (New variable costs + Fixed costs)

Of course, there may be more efficient ways to do that calculation, but what’s important - much like in the framework section - is to show your interviewer that you have a plan, in the form of a structured approach. You can write your plan on the sheet containing the data, then perform the calculations on a scrap sheet and fill in the results afterward.

5.2. Common business knowledge and formulas

Although some consulting firms claim they don’t evaluate candidates based on their business knowledge, familiarity with basic business concepts and formulae is very useful in terms of understanding the case studies you are given in the first instance and drawing inspiration for structuring and brainstorming.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already. For those coming from a different background, it may be useful to cover some.

Luckily, you don’t need a degree-level understanding of business to crack case interviews , and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy Course course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Below we include a few elementary concepts and formulae so you can hit the ground running in solving cases. We should note that you should not memorise these and indeed a good portion of them can be worked out logically, but you should have at least some idea of what to expect as this will make you faster and will free up much of your mental computing power. In what follows we’ll tackle concepts that you will encounter in the private business sector as well as some situations that come up in cases that feature clients from the NGO or governmental sector.

5.2.1 Business sector concepts

These concepts are the bread and butter of almost any business case so you need to make sure you have them down. Naturally, there will be specificities and differences between cases but for the most part here is a breakdown of each of them.

5.2.1.1. Revenue

The revenue is the money that the company brings in and is usually equal to the number of products they sell multiplied to the price per item and can be expressed with the following equation:

Revenue = Volume x Price

Companies may have various sources of revenue or indeed multiple types of products, all priced differently which is something you will need to account for in your case interview. Let’s consider some situations. A clothing company such as Nike will derive most of their revenue from the number of products they sell times the average price per item. Conversely, for a retail bank revenue is measured as the volume of loans multiplied by the interest rate at which the loans are given out. As we’ll see below, we might consider primary revenues and ancillary revenues: in the case of a football club, we might calculate primary revenues by multiplying the number of tickets sold by the average ticket price, and ancillary revenues those coming from sales of merchandise (similarly, let’s say average t-shirt price times the number of t-shirts sold), tv rights and sponsorships.

These are but a few examples and another reminder that you should always aim to ask questions and understand the precise revenue structure of the companies you encounter in cases.

5.2.1.2. Costs

The costs are the expenses that a company incurs during its operations. Generally, they can be broken down into fixed and variable costs :

Costs = Fixed Costs + Variable Costs

As their name implies, fixed costs do not change based on the number of units produced or sold. For example, if you produce shoes and are renting the space for your factory, you will have to pay the rent regardless of whether you produce one pair or 100. On the other hand, variable costs depend on the level of activity, so in our shoe factory example they would be equivalent to the materials used to produce each pair of shoes and would increase the more we produce.

These concepts are of course guidelines used in order to simplify the analysis in cases, and you should be aware that in reality often the situation can be more complicated. However, this should be enough for case interviews. Costs can also be quasi-fixed, in that they increase marginally with volume. Take the example of a restaurant which has a regular staff, incurring a fixed cost but during very busy hours or periods they also employ some part-time workers. This cost is not exactly variable (as it doesn’t increase with the quantity of food produced) but also not entirely fixed, as the number of extra hands will depend on how busy the restaurant is. Fixed costs can also be non-linear in nature. Let’s consider the rent in the same restaurant: we would normally pay a fixed amount every month, but if the restaurant becomes very popular we might need to rent out some extra space so the cost will increase. Again, this is not always relevant for case interviews.

5.2.1.3. Profit and profit margin

The profit is the amount of money a company is left with after it has paid all of its expenses and can be expressed as follows:

Profit = Revenue - Costs

It’s very likely that you will encounter a profitability issue in one of your case interviews, namely you will be asked to increase a company’s profit. There are two main ways of doing this: increasing revenues and reducing costs , so these will be the two main areas you will have to investigate. This may seem simple but what you will really need to understand in a case are the key drivers of a business (and this should be done through clarifying questions to the interviewer - just as a real consultant would question their client).

For example, if your client is an airline you can assume that the main source of revenue is sales of tickets, but you should inquire how many types of ticket the specific airline sells. You may naturally consider economy and business class tickets, but you may find out that there is a more premium option - such as first class - and several in-between options. Similarly to our football club example, there may be ancillary revenues from selling of food and beverage as well as advertising certain products or services on flights.

You may also come across the profit margin in case interviews. This is simply the percentage of profit compared to the revenue and can be expressed as follows:

Profit margin = Profit/Revenue x 100

5.2.1.4. Break-even point

An ancillary concept to profit, the break-even point is the moment where revenues equal costs making the profit zero and can be expressed as the following equation:

Revenues = Costs (Fixed costs + Variable costs)

This formula will be useful when you are asked questions such as ‘What is the minimum price I should sell product X?’ or ‘What quantity do I need to sell in order to recoup my investment?’. Let’s say in a case interview an owner of a sandwich store asks us to figure out how many salami and cheese salami sandwiches she needs to sell in order to break even. She’s spending $4 on salami and $2 for cheese and lettuce per sandwich, and believes she can sell the sandwiches at around $7. The cost of utilities and personnel is around $5000 per month. We could lay this all out in the break-even equation:

7 x Q ( quantity ) = (4+2) x Q + 5000 ( variable + fixed costs )

In a different scenario, we may be asked to calculate the break-even price . Let’s consider our sandwich example and say our owner knows she has enough ingredients for about 5000 sandwiches per month but is not sure how much to sell them for. In that case, if we know our break-even equation, we can simply make the following changes:

P ( price ) x 5000 = (4+2) x 5000 + 5000

By solving the equation we get to the price of $7 per sandwich.

5.2.1.5. Market share and market size

We can also consider the market closely with profit, as in fact the company’s performance in the market is what drives profits. The market size is the total number of potential customers for a certain business or product, whereas the market share is the percentage of that market that your business controls (or could control, depending on the case).

There is a good chance you will have to estimate the market size in one of your case interviews and we get into more details on how to do that below. You may be asked to estimate this in either number of potential customers or total value . The latter simply refers to the number of customers multiplied by the average value of the product or service.

To calculate the market share you will have to divide the company’s share by the total market size and multiply by 100:

Note, though, that learning the very basics of business is the beginning rather than the end of your journey. Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved. The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

5.3 Public sector and NGO concepts

As we mentioned, there will be some cases (see section 6.6 for a more detailed example) where the key performance indicators (or KPIs in short) will not be connected to profit. The most common ones will involve the government of a country or an NGO, but they can be way more diverse and require more thought and application of first principles. We have laid out a couple of the key concepts or KPIs that come up below

5.3.1 Quantifiability

In many such scenarios you will be asked to make an important strategic decision of some kind or to optimise a process. Of course these are not restricted to non-private sector cases but this is where they really come into their own as there can be great variation in the type of decision and the types of field.

While there may be no familiar business concepts to anchor yourself onto, a concept that is essential is quantifiability . This means, however qualitative the decision might seem, consultants rely on data so you should always aim to have aspects of a decision that can be quantified, even if the data doesn’t present itself in a straightforward manner.

Let’s take a practical example. Your younger sibling asks you to help them decide which university they should choose if they want to study engineering. One way to structure your approach would be to segment the problem into factors affecting your sibling’s experience at university and experience post-university. Within the ‘at uni’ category you might think about the following:

• Financials : How much are tuition costs and accommodation costs?
• Quality of teaching and research : How are possible universities ranked in the QS guide based on teaching and research?
• Quality of resources : How well stocked is their library, are the labs well equipped etc.?
• Subject ranking : How is engineering at different unis ranked?
• Life on campus and the city : What are the living costs in the city where the university is based? What are the extracurricular opportunities and would your sibling like to live in that specific city based on them?

Within the ‘out of uni’ category you might think about:

• Exit options : What are the fields in which your sibling could be employed and how long does it take the average student of that university to find a job?
• Alumni network : What percentage of alumni are employed by major companies?
• Signal : What percentage of applicants from the university get an interview in major engineering companies and related technical fields?

You will perhaps notice that all the buckets discussed pose quantifiable questions meant to provide us with data necessary to make a decision. It’s no point to ask ‘Which university has the nicest teaching staff?’ as that can be a very subjective metric.

5.3.1 Impact

Another key concept to consider when dealing with sectors other than the private one is how impactful a decision or a line of inquiry is on the overarching issue , or whether all our branches in our issue tree have a similar impact. This can often come in the form of impact on lives, such as in McKinsey’s conservation case discussed below, namely how many species can we save with our choice of habitat.

5.4 Common consulting concepts

Consultants use basic business concepts on an every day basis, as they help them articulate their frameworks to problems. However, they also use some consulting specific tools to quality check their analysis and perform in the most efficient way possible. These principles can be applied to all aspects of a consultant’s work, but for brevity we can say they mostly impact a consultant’s systematic approach and communication - two very important things that are also tested in case interviews. Therefore, it’s imperative that you not only get to know them, but learn how and when to use them as they are at the very core of good casing. They are MECE-ness, the Pareto Principle and the Pyramid principle and are explained briefly below - you should, however, go on to study them in-depth in their respective articles.

Perhaps the central pillar of all consulting work and an invaluable tool to solve cases, MECE stands for Mutually Exclusive and Collectively Exhaustive . It can refer to any and every aspect in a case but is most often used when talking about structure. We have a detailed article explaining the concept here , but the short version is that MECE-ness ensures that there is no overlap between elements of a structure (i.e. the Mutually Exclusive component) and that it covers all the drivers or areas of a problem (Collectively Exhaustive). It is a concept that can be applied to any segmentation when dividing a set into subsets that include it wholly but do not overlap.

Let’s take a simple example and then a case framework example. In simple terms, when we are asked to break down the set ‘cars’ into subsets, dividing cars into ‘red cars’ and ‘sports cars’ is neither mutually exclusive (as there are indeed red sports cars) nor exhaustive of the whole set (i.e. there are also yellow non-sports cars that are not covered by this segmentation). A MECE way to segment would be ‘cars produced before 2000’ and ‘cars produced after 2000’ as this segmentation allows for no overlap and covers all the cars in existence.

Dividing cars can be simple, but how can we ensure MECEness in a case-interview a.k.a. a business situation. While the same principles apply, a good tip to ensure that your structure is MECE is to think about all the stakeholders - i.e. those whom a specific venture involves.

Let’s consider that our client is a soda manufacturer who wants to move from a business-to-business strategy, i.e. selling to large chains of stores and supermarkets, to a business-to-consumer strategy where it sells directly to consumers. In doing so they would like to retrain part of their account managers as direct salespeople and need to know what factors to consider.

A stakeholder-driven approach would be to consider the workforce and customers and move further down the issue tree, thinking about individual issues that might affect them. In the case of the workforce, we might consider how the shift would affect their workload and whether it takes their skillset into account. As for the customers, we might wonder whether existing customers would be satisfied with this move: will the remaining B2B account managers be able to provide for the needs of all their clients and will the fact that the company is selling directly to consumers now not cannibalise their businesses? We see how by taking a stakeholder-centred approach we can ensure that every single perspective and potential issue arising from it is fully covered.

5.4.2 The Pareto Principle

Also known as the 80/20 rule, this principle is important when gauging the impact of a decision or a factor in your analysis. It simply states that in business (but not only) 80% of outcomes come from 20% of causes. What this means is you can make a few significant changes that will impact most of your business organisation, sales model, cost structure etc.

Let’s have a look at 3 quick examples to illustrate this:

• 80% of all accidents are caused by 20% of drivers
• 20% of a company’s products account for 80% of the sales
• 80% of all results in a company are driven by 20% of its employees

The 80/20 rule will be a very good guide line in real engagements as well as case interviews, as it will essentially point to the easiest and most straightforward way of doing things. Let’s say one of the questions in a case is asking you to come up with an approach to understand the appeal of a new beard trimmer. Obviously you can’t interview the whole male population so you might think about setting up a webpage and asking people to comment their thoughts. But what you would get would be a laundry list of difficult to sift through data.

Using an 80/20 approach you would segment the population based on critical factors (age groups, grooming habits etc.) and then approach a significant sample size of each (e.g. 20), analysing the data and reaching a conclusion.

5.4.3 The Pyramid Principle

This principle refers to organising your communication in a top-down , efficient manner. While this is generally applicable, the pyramid principle will most often be employed when delivering the final recommendation to your client. This means - as is implicit in the name - that you would organise your recommendation (and communication in general) as a pyramid, stating the conclusion or most important element at the top then go down the pyramid listing 3 supporting arguments and then further (ideally also 3) supporting arguments for those supporting arguments.

Let’s look at this in practice in a case interview context: your client is a German air-conditioning unit manufacturer who was looking to expand into the French market. However, after your analysis you’ve determined that the market share they were looking to capture would not be feasible. A final recommendation using the Pyramid Principle would sound something like this: ‘I recommend that we do not enter the German market for the following three reasons. Firstly, the market is too small for our ambitions of $50 million. Secondly the market is heavily concentrated, being controlled by three major players and our 5 year goal would amount to controlling 25% of the market, a share larger than that of any of the players. Thirdly, the alternative of going into the corporate market would not be feasible, as it has high barriers to entry.Then, if needed, we could delve deeper into each of our categories

6. Case examples or building blocks?

As we mentioned before, in your case interview preparation you will undoubtedly find preparation resources that claim that there are several standard types of cases and that there is a general framework that can be applied to each type of case. While there are indeed cases that are straightforward at least in appearance and seemingly invite the application of such frameworks, the reality is never that simple and cases often involve multiple or more complicated components that cannot be fitted into a simple framework.

At MCC we don’t want you to get into the habit of trying to identify which case type you’re dealing with and pull out a framework, but we do recognize that there are recurring elements in frameworks that are useful - such as the profitability of a venture (with its revenues and costs), the valuation of a business, estimating and segmenting a market and pricing a product.

We call these building blocks because they can be used to build case frameworks but are not a framework in and of themselves, and they can be shuffled around and rearranged in any way necessary to be tailored to our case. Hence, our approach is not to make you think in terms of case types but work from first principles and use these building blocks to build your own framework. Let’s take two case prompts to illustrate our point.

The first is from the Bain website, where the candidate is asked whether they think it’s a good idea for their friend to open a coffee shop in Cambridge UK (see the case here ). The answer framework provided here is a very straightforward profitability analysis framework, examining the potential revenues and potential costs of the venture:

While this is a good point to start for your case interview (especially taken together with the clarifying questions), we will notice that this approach will need more tailoring to the case - for example the quantity of coffee will be determined by the market for coffee drinkers in Cambridge, which we have to determine based on preference. We are in England so a lot of people will be drinking tea but we are in a university town so perhaps more people than average are drinking coffee as it provides a better boost when studying. All these are some much needed case-tailored hypotheses that we can make based on the initial approach.

Just by looking at this case we might be tempted to say that we can just take a profitability case and apply it without any issues. However, this generic framework is just a starting point and in reality we would need to tailor it much further in the way we had started to do in order to get to a satisfactory answer. For example, the framework for this specific case interview doesn’t cover aspects such as the customer’s expertise: does the friend have any knowledge of the coffee business, such as where to source coffee and how to prepare it? Also, we could argue there may be some legal factors to consider here, such as any approvals that they might need from the city council to run a coffee shop on site, or some specific trade licences that are not really covered in the basic profitability framework.

Let’s take a different case , however, from the McKinsey website. In this scenario, the candidate is being asked to identify some factors in order to choose where to focus the client’s conservation efforts. Immediately we can realise that this case doesn’t lend itself to any pre-packaged framework and we will need to come up with something from scratch - and take a look at McKinsey’s answer of the areas to focus on:

We notice immediately that this framework is 100% tailored to the case - of course there are elements which we encounter in other cases, such as costs and risks but again these are applied in an organic way. It’s pretty clear that while no standard framework would work in this case, the aforementioned concepts - costs and risks - and the way to approach them (a.k.a building blocks ) are fundamentally similar throughout cases (with the obvious specificities of each case).

In what follows, we’ll give a brief description of each building block starting from the Bain example discussed previously, in order to give you a general idea of what they are and their adaptability, but you should make sure to follow the link to the in-depth articles to learn all their ins and outs.

6.1 Estimates and segmentation

This building block will come into play mostly when you’re thinking about the market for a certain product (but make sure to read the full article for more details). Let’s take our Bain Cambridge coffee example. As we mentioned under the quantity bucket we need to understand what the market size for coffee in Cambridge would be - so we can make an estimation based on segmentation .

The key to a good estimation is the ability to logically break down the problem into more manageable pieces. This will generally mean segmenting a wider population to find a particular target group. We can start off with the population of Cambridge - which we estimate at 100.000. In reality the population is closer to 150.000 but that doesn’t matter - the estimation has to be reasonable and not accurate , so unless the interviewer gives you a reason to reconsider you can follow your instinct. We can divide that into people who do and don’t drink coffee. Given our arguments before, we can conclude that 80% of those, so 80.000 drink coffee. Then we can further segment into those who drink regularly - let’s say every day - and those who drink occasionally - let’s say once a week. Based on the assumptions before about the student population needing coffee to function, and with Cambridge having a high student population, we can assume that 80% of those drinking coffee are regular drinkers, so that would be 64.000 regular drinkers and 16.000 occasional drinkers. We can then decide whom we want to target what our strategy needs to be:

This type of estimation and segmentation can be applied to any case specifics - hence why it is a building block.

6.2 Profitability

We had several looks at this building block so far (see an in-depth look here ) as it will show up in most case interivew scenarios, since profit is a key element in any company’s strategy. As we have seen, the starting point to this analysis is to consider both the costs and revenues of a company, and try to determine whether revenues need to be improved or whether costs need to be lowered. In the coffee example, the revenues are dictated by the average price per coffe x the number of coffees sold , whereas costs can be split into fixed and variable .

Some examples of fixed costs would be the rent for the stores and the cost of the personnel and utilities, while the most obvious variable costs would be the coffee beans used and the takeaway containers (when needed). We may further split revenues in this case into Main revenues - i.e. the sales of coffee - and Ancillary revenues , which can be divided into Sales of food products (sales of pastries, sandwiches etc., each with the same price x quantity schema) and Revenues from events - i.e renting out the coffee shop to events and catering for the events themselves. Bear in mind that revenues will be heavily influenced by the penetration rate , i.e. the share of the market which we can capture.

6.3 Pricing

Helping a company determine how much they should charge for their goods or services is another theme that comes up frequently in cases. While it may seem less complicated than the other building blocks, we assure you it’s not - you will have to understand and consider several factors, such as the costs a company is incurring, their general strategic positioning, availability, market trends as well as the customers’ willingness to pay (or WTP in short) - so make sure to check out our in-depth guide here .

In our example, we may determine that the cost per cup (coffee beans, staff, rent) is £1. We want to be student friendly so we should consider how much students would want to pay for a coffee as well as how much are competitors are charging. Based on those factors, it would be reasonable to charge on average £2 per cup of coffee. It’s true that our competitors are charging £3 but they are targeting mostly the adult market, whose willingness to pay is higher, so their pricing model takes that into account as well as the lower volume of customers in that demographic.

6.4. Valuation

A variant of the pricing building block, a valuation problem generally asks the candidate to determine how much a client should pay for a specific company (the target of an acquisition) as well as what other factors to consider. The two most important factors (but not the only ones - for a comprehensive review see our Valuation article ) to consider are the net present value (in consulting interviews usually in perpetuity) and the synergies .

In short, the net present value of a company is how much profit it currently brings in, divided by how much that cash flow will depreciate in the future and can be represented with the equation below:

The synergies refer to what could be achieved should the companies operate as one, and can be divided into cost and revenue synergies .

Let’s expand our coffee example a bit to understand these. Imagine that our friend manages to open a chain of coffee shops in Cambridge and in the future considers acquiring a chain of take-out restaurants. The most straightforward example of revenue synergies would be cross-selling, in this case selling coffee in the restaurants as well as in the dedicated stores, and thus getting an immediate boost in market share by using the existing customers of the restaurant chain. A cost synergy would be merging the delivery services of the two businesses to deliver both food and coffee, thus avoiding redundancies and reducing costs associated with twice the number of drivers and vehicles.

6.5. Competitive interaction

This component of cases deals with situations where the market in which a company is operating changes and the company must decide what to do. These changes often have to do with a new player entering the market (again for more details make sure to dive into the Competitive Interaction article ).

Let’s assume that our Cambridge coffee shop has now become a chain and has flagged up to other competitors that Cambridge is a blooming market for coffee. As such, Starbucks has decided to open a few stores in Cambridge themselves, to test this market. The question which might be posed to a candidate is what should our coffee chain do. One way (and a MECE one) to approach the problem is to decide between doing something and doing nothing . We might consider merging with another coffee chain and pooling our resources or playing to our strengths and repositioning ourselves as ‘your student-friendly, shop around the corner’. Just as easily we may just wait the situation out and see whether indeed Starbucks is cutting into our market share - after all, the advantages of our product and services might speak for themselves and Starbucks might end up tanking. Both of these are viable options if argued right and depending on the further specifics of the case.

6.6. Special cases

Most cases deal with private sectors, where the overarching objective entails profit in some form. However, as hinted before, there are cases which deal with other sectors where there are other KPIs in place . The former will usually contain one or several of these building blocks whereas the latter will very likely have neither. This latter category is arguably the one that will stretch your analytical and organisational skills to the limit, since there will be very little familiarity that you can fall back on (McKinsey famously employs such cases in their interview process).

So how do we tackle the structure for such cases? The short answer would be starting from first principles and using the problem driven structure outlined above, but let’s look at a quick example in the form of a McKinsey case :

The first question addressed to the candidate is the following:

This is in fact asking us to build a structure for the case. So what should we have in mind here? Most importantly, we should start with a structure that is MECE and we should remember to do that by considering all the stakeholders . They are on the one hand the government and affiliated institutions and on the other the population. We might then consider which issues might arise for each shareholder and what the benefits for them would be, as well as the risks. This approach is illustrated in the answer McKinsey provides as well:

More than anything, this type of case shows us how important it is to practise and build different types of structures, and think about MECE ways of segmenting the problem.

7. How Do I prepare for case interviews

In consulting fashion, the overall preparation can be structured into theoretical preparation and practical preparation , with each category then being subdivided into individual prep and prep with a partner .

As a general rule, the level and intensity of the preparation will differ based on your background - naturally if you have a business background (and have been part of a consulting club or something similar) your preparation will be less intensive than if you’re starting from scratch. The way we suggest you go about it is to start with theoretical preparation , which means learning about case interviews, business and basic consulting concepts (you can do this using free resources - such as the ones we provide - or if you want a more through preparation you can consider joining our Case Academy as well).

You can then move on to the practical preparation which should start with doing solo cases and focusing on areas of improvement, and then move on to preparation with a partner , which should be another candidate or - ideally - an ex-consultant.

Let’s go into more details with respect to each type of preparation.

7.1. Solo practice

The two most important areas of focus in sole preparation are:

• Mental math

As we mentioned briefly, the best use of your time is to focus on solving cases. You can start with cases listed on MBB sites since they are clearly stated and have worked solutions as well (e.g. Bain is a good place to start) and then move to more complex cases (our Case Library also offers a range of cases of different complexities). To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

Another important area of practice is your mental mathematics as this skill will considerably increase your confidence and is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

7.2. Preparation with a partner

There are aspects of a case interview - such as asking clarifying questions - which you cannot do alone and this is why, after you feel comfortable, you should move on to practice with another person. There are two options here:

• Practicing with a peer
• Practicing with an ex-consultant

In theory they can be complementary - especially if you’re peer is also preparing for consulting interviews - and each have advantages and disadvantages. A peer is likely to practice with you for free for longer, however you may end up reinforcing some bad habits or unable to get actionable feedback. A consultant will be able to provide you the latter but having their help for the same number of hours as a peer will come at a higher cost. Let’s look at each option in more detail.

7.2.1. Peer preparation

Once you have worked through eight cases solo, you should be ready to simulate the case interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting. If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice. We recommend practicing around 10 to 15 ‘live’ cases to really get to a point where you feel comfortable.

7.2.2. Preparation with a consultant

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Practicing with an ex consultant is essentialy a simulation of a case interview. Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even just a few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering bespoke mentoring programmes , where you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

7.3. Practice for online interviews

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

7.4. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

8. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

8.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the case interview can then begin.

8.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important . If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

8.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

8.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

8.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

8.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

8.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote case interviews are, in effect, around making sure you come across as effectively as you would in person.

8.2.1. Connection

It sounds trivial, but a successful video case interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

8.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

8.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom case interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your case interview actually is. If your case interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

8.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom case interview, but more so.

9. How we can help

There are lots of great free resources on this site to get you started with preparation, from all our articles on case solving and consulting skills to our free case library and peer practice meeting board .

To step your preparation up a notch, though, our Case Academy course will give you everything you need to know to solve the most complex of cases - whether those are in live case interviews, with chatbots, written tests or any other format.

Whatever kind of case you end up facing, nothing will bring up your skillset faster than the kind of acute, actionable feedback you can get from a mock case interview a real, MBB consultant. Whilst it's possible to get by without this kind of coaching, it does tend to be the biggest single difference maker for successful candidates.

While the consulting case study interview may seem daunting at first, most cases follow a typical song-and-dance. Once you get a hang of it, prepping feels much more manageable. The first part of this guide will give a broad overview of the case interview. The second part will break out the typical structure of an interviewee-led case. The last part will dive into each component, with tips and suggestions for preparing. Note that some firms may have their own specific case interview style. Be sure to familiarize yourself with your target firms’ interview processes before the time comes to recruit.

Case interviews involve tackling a business issue or problem faced by a company (the client). These interviews allow consulting firms to gauge candidates’ ability to perform the job. Specifically, firms are testing whether candidates can:

• Think in a structured and creative way
• Analyze and interpret new information
• Communicate persuasively and succinctly

Most firms conduct interviewee-led cases, as outlined in the guide below. In these cases, the candidate is expected to drive the case forward by asking the interviewer for data or information relevant to forming the recommendation. A few firms, most notably McKinsey, are interviewer-led, meaning that the interviewer will be the one guiding the discussion.

Below are a few common types of cases that you can expect to receive. Some cases can be several types all in one (lucky you!):

• Profitability - Determine cause for profit decline and / or ideas for increasing profit; you will rarely get a standalone profitability case – It will usually be rolled up in another case type
• Growth - consider strategies for company growth; could be through sales or market share
• Market Entry / New Business - Assess attractiveness of entering new geography / business / sector and method for entering
• Due Diligence / M&A - Assess attractiveness of purchasing / acquiring a company or business; client can be another company or a financial sponsor
• Competitive Response - Address a competitor’s recent action (e.g., new acquisition, change in pricing strategy)
• Non-Traditional - Similar to the other cases but the client (non-profit, NGO, education-focused entity) has different objectives than a typical corporate company

Case Interview Components

• Prompt: Interviewer reads aloud the case while the interviewee takes notes
• Recap: Interviewee provides a high-level summary of the case and confirms accuracy of information written
• Clarifying Questions: Interviewee asks 2-3 high-level questions
• Structuring (<2 minutes): Interviewee takes a few minutes create a roadmap for approaching the case
• Framework Presentation (2-3 minutes): Interviewee reviews the structure with the interviewer, who may have follow-up questions. Interviewee then moves the case forward by asking for additional information
• Brainstorming: Interviewee is expected to list out several solutions or ideas (e.g., cost drivers for an industry, ways to increase sales)
• Exhibits: Interviewee will be given data in forms such as graphs or charts and expected to provide high-level insights
• Math: Interviewee will be asked to perform a calculation with the new information or using data from the exhibits. Oftentimes, interviewee is not given enough information and must ask for the relevant data
• Synthesis and Recommendation (2-3 minutes) : Interviewee provides the answer first, then supporting facts from the case, and finally risks and next steps

Setup (2-3 minutes)

Prompt : The interviewer may be giving you A LOT of information - don’t write down everything verbatim. Jot down facts and figures, the client name, and the objective(s). If you miss something or don’t remember what a number means, you can ask after your recap.

• Prep: Have a friend read you several different case interview prompts and practice taking down notes. Create your own shorthand and learn how to recognize extraneous pieces of information

Recap : I always reference the client by name and start my recap with the objective(s) first, since this is the most important part of the case. The recap should be summarized, not verbatim, and you should be checking that the figures you wrote down are correct.

• Prep: Practice summarizing your notes out loud instead of repeating the case verbatim. Time yourself to make sure it’s <1 minute.

Clarifying Questions : Very detailed questions should be saved for the case. Clarifying questions are meant to help you with your structure or alleviate any confusion. Keep these at 2-3 questions. I usually ask questions pertaining to:

• Language/terminology - The interviewer won’t expect you to know the nuances of every industry or practice area. It is better you start off the case on the right footing by asking for clarifying definitions
• Goals/objectives - I always ask if there are other goals the company has in mind and, if relevant, specific financial targets or timeframe. Sometimes, the objective given is vague, so I will ask the interviewer to be more specific.
• Business model or geography - Very helpful for cases in niche industries; understanding geography can also prompt you to think about factors like labor cost or global competition
• Scope - To save you time from considering every possibility, you can ask whether the company is leaning towards one option or excluding a set of options completely
• Prep: Have a friend read you case prompts and then practice asking 2-3 clarifying questions on the fly. Try to think of them as you’re taking down notes and giving the recap. Are they helping you with your structuring or are you asking the first thing that pops into your head? Are they broad enough or overly detailed? Are there types of questions you should be asking but keep forgetting?

Framework (4-5 minutes)

Structuring (<2 minutes) : Do not use the word “framework” during the interview. I ask if I could have time to “gather my thoughts” when I am structuring. In your structure, you should have at least three but no more than five “buckets.” These are areas that you want to explore in order to solve the case. In each bucket, there should be at least three sub-bullets. Make sure there is no overlap between the buckets.

• Prep: Time yourself structuring your roadmaps. Be comfortable with recalling the different buckets you should be considering for each type of case and brainstorming sub-bullets for those buckets. It’s okay to go over two minutes when you first start, but as you get comfortable, make sure you are becoming more efficient. For example, as you become more familiar with the buckets, you don’t need to write down every example for the sub-bullets, they will become muscle memory as you recite them out loud. Review the suggested frameworks for the case and take note of whether there are vital topics you keep forgetting or whether there are unnecessary buckets you keep adding. There is no one “right” answer, but your roadmap should enable you to uncover the necessary information to make your recommendation.

Presenting: Introduce the high-level buckets first before diving into each one. You will want to “customize” your framework to the specific case you’re working on. This does not mean creating a custom framework for every single case. You can use the same topics for similar types of cases (but ensure that those topics are relevant - some cases sneakily rule out an entire topic to see if you are paying attention), but you need to make sure that you are using case-specific language and examples when you present. This shows that you are thinking about the specific problem, not just recycling a generic framework. After going through the structure, pause and ask if the interviewer has any questions. Then, give your hypothesis and state which bucket you want to start with by asking for data pertaining to that bucket and why you want it.

• Prep: Present your structures out loud and note whether you are rambling or being case-specific in your language. If you find that your presentation is too long, consider cutting down on the examples or explanations. Be succinct and say enough to get your point across. Don’t just move on to the next case if your presentation falls short. Keep practicing until you feel satisfied and make mental notes for the next case.

Interview “Questions” (10-20 minutes)

For each type of question, you are going to be doing the same things: answering the question, providing insights, conveying how it impacts your recommendation, and driving the case forward. Every time you have “answered” a question, you want to be thinking, “ What else do I need? What’s the logical path forward ?” The only way you can prepare for this is to run through entire cases! Remember, your framework is your friend. Refer back to it often if you don’t know where to go next.

Brainstorming : You will want to structure your ideas into MECE buckets. They can be fairly simple (financials vs. non-financials, external vs. internal, etc.). Similar to your framework, you will give a preview of the buckets first before going into the details of each and you will need to ensure that it is “custom” for your case. If a structure doesn’t naturally come to you, you can create a pseudo-structure by organizing how you will present your brainstorm. For example, you can state how many ideas you have from the onset or say that you will first go through the ideas first and then the associated risks.

This is a highly debated practice, but I always ask for a few seconds so I can think of a structure (they may say no). Don’t take more than 30 seconds because you can add to your buckets as you are presenting.

For non-technical brainstorms, be creative! For example, when interviewers asked about how to increase sales for a consumer-facing retail company, I would bring up TikTok campaigns and celebrity endorsements as a few ideas. Have fun with it!

Occasionally, interviewers will prod you with, “What else?” This does not always mean you didn’t give enough ideas. Sometimes it’s the opposite – they are looking to challenge you or see how you will react. Just roll with it - if you don’t have anything else, say so.

• Prep: Practice brainstorming for different types of prompts. Collect a bank of general ideas and solutions that can be customized for use across industries. Try to think of as many ideas as you can (four to six at the very least) and exercise that creative muscle. To help you with structuring, have a list of “easy” MECE buckets that you can pull out on the fly.

Exhibits : First, give an overview of the exhibit. As an example, for graphs say what the axes represent, tie it back to the case, and give your interpretation of those axes. This gives the interviewer a chance to course-correct if you misinterpreted the exhibit. Give some insight, even if it is low-hanging fruit, and tie it back to the case. There are three levels of insights for both exhibits and math:

• What the numbers say, patterns/trends (X is smaller than anticipated, Y is the largest driver)
• What the client should do (enter the market, cancel plans, plan for launch)
• What we should do next (reconsider something specific, research more data on X, move on to Y)

Oftentimes, exhibits will tie into a calculation. If you are given an exhibit with data that can be used to calculate more insightful information, tell the interviewer that you would like to make those calculations. The interviewer will lead you down that path regardless but it is more impressive if you call it out.

• Prep: Run through different types of exhibits and see how many insights from each level you can pull out. Practice anticipating what type of data you need next in order to move ahead in the case or whether you can/should calculate anything from the data given. Don’t be too insightful though – you only have a limited amount of time to run through the case.

Math : Before you start calculating anything, it is critical for you to confirm what you are solving for and that the information you wrote down is correct. SUPER IMPORTANT – answer the question that is being asked !!  If the interviewer is asking for the incremental profit from a certain strategy, you don’t want to calculate the total profit from the strategy. Active listening is so important!

As you know by now, structure is everything. Again, I always ask for a few seconds to organize my thoughts (the worst thing they can say is no). Set up the problem before you start calculating. This allows you to identify whether there is data missing. Walk the interviewer through your method and ask for missing data. You may need to make your own assumptions or estimates – be sure you can justify them.

If your method is off, the interviewer will usually guide you back to the right path. This saves you from wasting time calculating the incorrect answer. Be sure to pay attention when the interviewer is trying to coach you.

As you are solving the problem, walk the interviewer through each calculation and use math shortcuts as much as possible. Again, if you make a math error, the interviewer can stop you before you go down the entire path. Save time by only calculating what is important for the case and understanding what you can skip.

• Prep: Practice setting up the problem, walking the interviewer through your proposed method, and verbalizing the calculations out loud. On paper, make sure your calculations are being done neatly and not all over the place. Look for different math shortcuts and try them out. Not all of them will fit your style, but you might find new tricks. Track whether you are answering the right questions. Once again, active listening is critical to your candidacy. Once you have correctly solved the problem, make sure you are thinking about the, “So what?” Determine how that number impacts your recommendation and where you should go next.

Synthesis and Recommendation (2-3 minutes)

Again, I always ask for a few seconds to collect your thoughts (<30 secs). If the “CEO is already in the elevator,” they may say no. Have a definitive stance – start with your recommendation and then provide two to three supporting facts using data from the case.

Address risks and next steps (i.e., what is the required analysis/gameplan – this is like real life where the firm is trying to sell additional projects). Your recommendation should be <2 minutes. Frankly, the interviewer has most likely made a decision on your candidacy. Don’t ramble and try to finish strong.

The hardest part of this is pulling out the supporting data in a succinct way. Throughout the case, you should be jotting down notes. I tend to circle what I believe to be relevant supporting data. When you present it, don’t be too specific or granular. You want your recommendation to be punchy.

• Prep: Run through whole cases where you are tracking the relevant supporting data along the way. Time your recommendation and practice verbalizing the information concisely. Don’t forget the risks and next steps. I usually have a list of generic risks (e.g., competitor response, regulation, inaccurate projections) that I can “customize” on the off-chance I’m scrambling to think of some. Your next steps can be collecting additional data to support your recommendation or ways to address those risks.

Final Thoughts

• Your approach is more important than the solution – The interviewer is trying to understand how you think. Some cases have data that support recommendations in either direction. The key piece is that you are able to back your stance using the facts and data uncovered during the interview.
• Deadends are okay – There will be times when you make multiple requests for data and the interviewer does not have it. That’s perfectly fine! You can’t read the interviewer’s mind and the case could go in so many directions. Just look back at your framework to see where else you can proceed.
• Be coachable – It’s not the end of the world if your method is wrong or if you misinterpreted an exhibit. The interviewer wants to see that you are actively listening and can take feedback and improve. Don’t freak out! Stay calm! Listen to what the interviewer is trying to tell you.

This guide only scratches the surface of case interviews. The best way to prepare for case interviews is to get your reps in with entire cases.

Keep reading to find out how to use case interview examples to ace your case.

How to Use Case Interview Examples to Ace Your Case

1. start your case interview preparation early..

You’ll need to practice dozens of case interview examples to get good enough to receive an offer from one of the top consulting firms. This is not something you can cram the night before an interview.

Start as soon as possible.

2. Don’t Read Straight through Sample Case Interview Examples or Passively Watch Videos.

Some people think that the best way to improve their chances of passing a case interview is by reading as many cases interview examples as they can.

This is like reading about how to play tennis but never picking up a racket. To get better at tennis, for example, you need to actually pick up a ball and be active. The same applies to your interview preparation.

Stop and think at each step in the case interview question. Come up with your own answer and say it out loud. Practice driving each part of the case interview example yourself.

• How would you structure your analysis of the problem?
• What questions would you ask the interviewer?
• How would you set up the case math problem?
• What recommendation would you make to the client?

After you’ve developed your answer, compare it to the suggested answer for the case.

What did you get right?

How did your answer and the case interview example answer differ?

Are there things you miss consistently across multiple case interview examples?

The answers to these  case interview examples can look simple when you just read through them, but it’s not easy to come up with all the key aspects of the solution on your own.

Nail the case & fit interview with strategies from former MBB Interviewers that have helped 89.6% of our clients pass the case interview.

3. Find Partners to Practice Case Interviews with.

Teamwork is an important part of consulting work, so get ready for it now. Find a case interview practice partner, preferably someone else who’s applying to jobs in the management consulting industry because they’ll know more about what recruiters are looking for.

Practicing cases with a partner provides the opportunity to get feedback from someone else on what you’re doing well and what you need to improve. Additionally, you’ll learn a lot by watching how your partner solves sample case studies.

Look for aspects of their approach that are effective as well as what they could do better. Working with a partner will make your consulting interview practice feel more real.

Similar to how you need a tennis partner to feel what is like to play tennis, you need a case partner to experience what a case interview is like.

4. Master the 4 Parts of the Case Interview.

In our article on Case Interview Prep , we discussed the 4 parts of the case interview: the opening, structure, analysis, and conclusion. As you practice with consulting case interview examples, practice each of these 4 parts to ensure you’re strong at them all.

5. Avoid Case Burnout.

A case zombie is someone who’s grown tired of casing from doing too much of it. Their answers feel rehearsed, not conversational. 

They may seem bored, not engaged in solving the problem. They’ll be less creative in their solutions. They certainly won’t pass the airport test!

Avoid becoming a case zombie by practicing smarter, not harder.

Video: Case Interview Examples – Questions & Answers

In the following case interview example, Davis Nguyen, founder of My Consulting Offer solves McKinsey’s SuperSoda case.  The video is broken into 4 parts of the case interview.

Remember, don’t just watch the video. Stop the video and provide your own answer before listening to Davis’s  answer to the case question.

Step 1: Case Interview Example Opening – Ensure you understand the client and the problem you’ll be solving in the case.

Step 2: case interview example structure – break the problem down into smaller parts. make sure you cover all key case issues., step 3: case interview example analysis – ask questions, gathering information from graphs and charts provided by the interviewer, do case math, and provide insight into the client’s business problem based on what you learn., step 4: case interview example recommendation – develop a rational recommendation for the client based on all you’ve learned throughout the case interview., tips for acing your consulting case interviews – the difference between average & exceptional, case interview opening.

The opening is a great point to ask “dumb” questions because, at this point, you’re not expected to know much about the client and their business. 

Here your goal is to understand the client, their business, and what a successful project will look like.

Don’t shy away from asking for clarification on things that will help you better understand the business problem and solve it. For example, if you don’t know how life insurance works and the case is about life insurance, then ask.

After ensuring you understand the client and their problem, the next thing to ask about is key metrics of success. 

For example, the client may want to find new avenues for growth. Are they looking for a 5% increase in revenue or to double their business?

Finding out what success looks like in the client’s eyes will ensure you work to deliver a solution that meets their expectations, not one that’s underwhelming.

After you find out what success looks like, ask further probing questions to better understand the client, their business, and any constraints on solving the case.

Examples of Relevant Questions to ask Your Interviewer 

Examples of relevant questions about the client might include the geography they operate in or the sector of their industry they are strongest in. 

Examples of relevant questions about their business might include what products or services are most profitable or most important to their customers. 

Examples of relevant questions about the problem might include whether there are any costs that can’t be cut or what the maximum amount the client is able to invest in developing a new product. 

Asking these types of questions up front will give you a better context for solving the client’s problem and make it more likely that you will solve the case interview.

Case Interview Structure

You’ll need a framework to make sure your analysis covers all key aspects of the consulting case. 

You can use one of the many standard Case Interview Frameworks we’ve outlined , but top interviewees develop their own framework for analyzing the case interview question. 

Their frameworks may include pieces of one or more of the standard frameworks but are tailored to the particular business problem they’re discussing. 

Good frameworks are hypothesis-driven, that is to say they can be tested similar to the science experiment, so that the answer is either a “yes” or “no.” For example, examining your bank account to see, “if I have $400 for a ticket” is an example.

Second, good frameworks cover all topics relevant to the answer. For example, if the client is opening up a new hotel in a foreign country, checking out the existing competition should be part of the framework.

As you study more about interactive case interviews and practice them you’ll develop a sense for what factors are relevant or not relevant to the case at hand.

Finally, a good structure will be  MECE  or mutually exclusive and collectively exhaustive.

This means the framework will break down the market or population being analyzed into segments that include every part of the whole (collectively exhaustive), and each segment of the market or member of the population will show up in one and only one category without overlap (mutually exclusive). 

For example, if you divide the target market for a retail product into segments by age, these segments would be MECE:

•  10-19,
• 40-49, etc.

The categories 15-25, 20-30, 27-35 would not be MECE because people could be counted twice. 

Case Interview Analysis

In the analysis phase of your case interview example, you’ll ask questions to get the information you need to solve the client’s business problem. Your questions will likely lead you to one of the 4 types of analysis that are common in consulting interviews: market sizing, brainstorming, quantitative reasoning (case math), or reading exhibits. 

No matter which of these types of analysis comes up, there’s a 4-step method that ensures you can crack the case. 

This 4-step method is:

• Ask for data,
•  Interpret the data,
•  Provide insight, and 
• Outline next steps. 

The data you ask for will depend on the case interview question you’re solving. For example, if the question is about profitability, you’ll need to know about the client’s finances: dig into revenues and costs. 

For example, if you find that the client’s revenues are flat while their costs have been rising, you’ll know that the problem is in the cost structure and that you’ll need to examine costs more closely.

Next, provide insight. As you examine costs further, you’ll find out why they’ve grown faster than revenues. 

This insight will naturally lead to the next steps. What does the client need to do to get costs under control and fix their profitability problem? 

You may need to go through this 4-step method a couple of times, focusing on different aspects of the client’s business problem. 

Once you’ve examined and developed insight into all key aspects of the problem, your next step will be to conclude the interview with a recommendation for the client.

Case Interview Conclusion

At this point, you’ve hopefully cracked the case and are ready to present your recommendations to the client (your interviewer). 

The best way to do this is to use the 5R approach:

• Recap – restate the business problem you’ve analyzed. In consulting this is done because a CEO might have hired 5 McKinsey teams and can’t remember which one you are on. 
• Recommendations – Provide the solution your analysis led to. We lead with the recommendation because it is the most important piece of information. Stating it first and clearly puts everyone on the same page.
• Reasons – Summarize the key facts and insights that lead you to your recommendations. 
• Risks – Outline any risks the client should be aware of as they implement your recommendations. No recommendation has a 100% probability of success. Clients need to be aware of business risks in the same way patients need to understand the side effects of drugs.
• Retaining the client – Provide next steps for how you can help the client ensure success. As consultants, we are paid for helping our clients. If there is a natural extension of the work as the client implements the team’s recommendations, we should tell them how we can provide further assistance (and ultimately make money for your firm). 

While most candidates will address their recommendations and possibly the reasons for their recommendations, few will hit all these points. 

In particular, outlining risks and further ways you can help the client will differentiate you from other candidates and help you to advance  to the second round of interviews or get the offer.

Example Deloitte Case Study

Consulting case studies are real-life examples of consulting projects that have been completed by consulting firms. These studies are used to showcase the expertise and problem-solving abilities of the consulting firm, as well as to provide potential clients with an understanding of the type of work that the firm can deliver. Consulting case studies typically detail the challenge that the client was facing, the approach taken by the consulting firm to address the challenge, and the outcomes and results achieved as a result of the project.

Consulting case studies are a valuable tool used by professionals in the consulting industry to showcase their expertise and problem-solving skills. These case studies typically outline a specific business challenge or issue that a client faced, and detail how the consulting firm addressed and resolved the problem. By presenting real-world examples of their work, consulting firms are able to demonstrate their capabilities to potential clients and establish credibility in the industry.

The purpose of consulting case studies is twofold. Firstly, they serve as a means for consulting firms to highlight their success stories and showcase their ability to deliver results for clients. By detailing the specific steps taken to address a particular issue, consulting firms can illustrate their problem-solving process and demonstrate the value they bring to their clients. This can be especially valuable for potential clients who are evaluating different consulting firms and looking for evidence of past success.

Secondly, consulting case studies can also serve as a learning tool for professionals in the consulting industry. By studying successful case studies, consultants can gain insights into different problem-solving approaches, strategies, and best practices. This can help them improve their own consulting skills and better understand how to approach similar challenges in the future. Overall, consulting case studies play a crucial role in showcasing the expertise of consulting firms, attracting new clients, and promoting continuous learning and improvement within the industry.

How to Analyze Consulting Case Studies 

Analyzing Consulting Case Studies involves breaking down the problem statement, identifying key challenges, understanding the approach taken by the consulting firm, evaluating the effectiveness of the solutions proposed, and assessing the overall impact of the project. By closely examining the details of each case study, individuals can gain a deeper understanding of the consulting process and learn valuable lessons that can be applied to their own projects.

In order to effectively analyze Consulting Case Studies, it is important to ask critical questions such as:

• What were the main challenges faced by the client?
• What approach did the consulting firm take to address these challenges?
• What were the key findings and recommendations made by the consulting team?
• What were the outcomes of the project in terms of financial impact, operational improvements, or strategic benefits?
• What lessons can be learned from this case study that can be applied to future consulting projects?

By answering these questions and thoroughly examining the details presented in Consulting Case Studies, individuals can gain valuable insights into the consulting process and learn how to approach similar challenges in their own work. 

Tips for Crafting a Strong Consulting Case Study 

Case studies are a valuable tool for consultants to showcase their expertise and experience. By presenting a detailed analysis of a client project, consultants can demonstrate their problem-solving skills and the results they have achieved. To create a strong consulting case study, there are several tips to keep in mind.

First and foremost, it is important to choose a relevant and compelling client project to focus on. Selecting a project that highlights your expertise and showcases your ability to deliver results will help to capture the attention of potential clients. Additionally, be sure to include specific details about the client’s goals, challenges, and the solutions you implemented. Providing this context will help readers understand the complexity of the project and the impact of your work.

In addition to outlining the project details, it is important to highlight the results and outcomes of your work. Quantifying the impact of your solutions with specific metrics and data will provide concrete evidence of your success. This information can help potential clients understand the tangible benefits of working with you and can help establish your credibility as a consultant. By following these tips and creating a well-crafted case study, consultants can effectively showcase their skills and attract new clients. 

Tips for Writing a Compelling Case Study Narrative

Crafting a compelling case study narrative is essential for capturing the attention of your audience and effectively communicating the value of your work. When writing your case study, it is important to create a clear and engaging narrative that highlights the problem-solving process and the impact of your solutions. Start by outlining the client’s goals and challenges, and then explain how you approached the project and developed a strategic solution.

To keep readers engaged, consider incorporating storytelling elements into your case study. By providing a narrative structure with a clear beginning, middle, and end, you can create a compelling story that draws readers in and keeps them interested. Additionally, be sure to use clear and concise language to explain complex concepts and technical details in a way that is accessible to a wide audience.

Furthermore, don’t forget to include quotes or testimonials from the client to add credibility and perspective to your case study. Hearing directly from the client about their experience working with you can help reinforce the effectiveness of your solutions and build trust with potential clients. By following these tips for writing a compelling case study narrative, consultants can effectively communicate the value of their work and attract new clients. 

Tips for Designing an Engaging Case Study Layout

In addition to crafting a strong case study narrative, the design of your case study is also crucial for capturing and holding the attention of your audience. An engaging layout can help to visually communicate the key points of your case study and make it easier for readers to digest the information. When designing your case study, consider using a clean and professional layout with clear headings, bullet points, and visuals to break up the text and highlight important information.

Incorporating visual elements such as charts, graphs, and images can help to illustrate your key points and make the content more engaging and easy to understand. Including before-and-after comparisons or visual representations of the project’s impact can provide a powerful visual representation of your work. Additionally, be sure to use a consistent color scheme and typography to create a cohesive and visually appealing design.

Furthermore, consider including call-to-action buttons or contact information at the end of your case study to encourage readers to take the next step and reach out to learn more. By designing an engaging case study layout that complements your narrative, consultants can effectively showcase their work and attract new clients.

Consulting case studies are a crucial part of the interview process for landing a job in the consulting industry. In order to succeed, it’s important to avoid common mistakes in interpreting these case studies. 

One common mistake is jumping to conclusions without fully understanding the problem at hand. It’s important to take the time to thoroughly analyze the case study and ask clarifying questions if needed. Another mistake is not structuring your analysis in a logical and organized way. This can make it difficult for the interviewer to follow your thought process and ultimately lead to a weaker performance. 

Additionally, failing to prioritize your analysis can result in spending too much time on less important aspects of the case study. It’s crucial to identify the most critical issues and address them first in order to demonstrate your problem-solving skills effectively. Finally, overlooking the importance of communication skills can also be a mistake. Clearly articulating your analysis and insights is just as important as the analysis itself. 

Overall, by avoiding these common mistakes in consulting case study interpretation, you can increase your chances of success in the interview process and ultimately secure the job of your dreams.

• Jumping to conclusions without fully understanding the problem 
• Not structuring analysis in a logical and organized way 
• Failing to prioritize analysis 
• Overlooking the importance of communication skills

In the world of consulting, data plays a crucial role in shaping case studies and providing valuable insights for clients. When analyzing a business problem or opportunity, consultants rely on data to understand the current state of affairs, identify trends, and make informed recommendations. By collecting and analyzing data, consultants can uncover hidden patterns, correlations, and insights that can lead to more effective solutions.

Data also serves as a foundation for evidence-based decision-making in consulting. When presenting a case study to a client, consultants must back up their recommendations with solid data and analysis. This not only lends credibility to their findings but also helps clients understand the rationale behind the proposed solutions. Without data, recommendations may be perceived as subjective opinions rather than well-supported conclusions.

Data allows consultants to measure the impact of their recommendations and track progress over time. By setting clear metrics and key performance indicators, consultants can monitor the success of their interventions and make adjustments as needed. This data-driven approach helps ensure that consulting projects deliver tangible results and drive long-term value for clients. Ultimately, data is the cornerstone of consulting case studies, providing the evidence and insight needed to drive effective decision-making and create meaningful impact for clients. 

How Data Improves Decision-Making in Consulting Case Studies

One of the key benefits of using data in consulting case studies is its ability to improve decision-making processes. By analyzing data, consultants can identify key opportunities and challenges, assess the potential impact of different strategies, and make informed decisions that lead to better outcomes for clients. Data provides a solid foundation for decision-making, enabling consultants to avoid relying on gut instincts or personal biases.

Moreover, data-driven decision-making in consulting case studies helps mitigate risks and uncertainties. By examining historical data, market trends, and industry benchmarks, consultants can anticipate potential obstacles and develop contingency plans to address them. This proactive approach not only minimizes the likelihood of unexpected setbacks but also increases the likelihood of success for consulting projects.

Data also empowers consultants to test hypotheses, validate assumptions, and explore alternative scenarios in their case studies. By leveraging data analytics tools and techniques, consultants can conduct robust analyses that uncover valuable insights and inform strategic decisions. This iterative process of data-driven decision-making allows consultants to refine their recommendations, optimize their strategies, and deliver greater value to their clients. Ultimately, data enhances the quality of decision-making in consulting case studies, leading to more effective solutions and positive outcomes for clients.

How to Present Your Findings from Consulting Case Studies 

Consulting case studies are a valuable tool for showcasing your expertise and problem-solving skills to potential clients. When it comes to presenting your findings from these case studies, it is important to approach the task with both clarity and creativity. 

One effective way to present your findings is to start by clearly outlining the problem or challenge that you were tasked with addressing. This sets the stage for the rest of your presentation and helps your audience understand the context of your work. Next, explain your approach to solving the problem, including any research or analysis you conducted. This shows your audience that your findings are backed up by solid data and evidence. 

After presenting your approach, it is important to showcase the results of your work. This could include metrics such as improved efficiency or increased revenue, as well as any qualitative feedback from the client. Highlighting the positive outcomes of your consulting work helps to build credibility and demonstrate the value you provide to clients. Finally, conclude your presentation by summarizing the key takeaways from the case study and reiterating how your skills and expertise can benefit potential clients in similar situations. By following these steps, you can effectively present your findings from consulting case studies in a compelling and convincing way to get more clients . 

Tips for Creating Engaging Visuals for Your Consulting Presentations 

Visual aids can be a powerful tool for enhancing your consulting presentations and capturing the attention of your audience. When creating visuals for your presentations, it is important to keep a few key tips in mind to ensure that they are engaging and effective. 

One important tip is to keep your visuals simple and easy to understand. Avoid cluttering your slides with too much information or complex graphics, as this can overwhelm your audience and distract from your main points. Instead, use clean and clear visuals that help to reinforce your message and make it easier for your audience to follow along. 

Another tip is to use a variety of visual formats to keep your audience engaged. This could include charts, graphs, images, and even videos. By mixing up the types of visuals you use, you can create a dynamic and interesting presentation that holds the attention of your audience. Additionally, remember to use visual aids to enhance your verbal presentation, rather than replace it. Your visuals should complement your spoken content and help to reinforce your key points. By incorporating these tips into your consulting presentations, you can create engaging visual aids that help to bring your findings to life and make a lasting impression on your audience.

Deloitte published a great case study for a footwear company. In 2013, a competitor, Badger, launched a successful line of affordable work boots, prompting Duraflex, another footwear company, to rethink their strategy. With limited resources, Duraflex needed to decide whether to focus on competing in the work boot market or strengthening their position in casual boots.

Duraflex sought help from a top consulting firm in January 2014. The consultants conducted research to provide valuable insights for decision-making. They started by conducting a survey with 500 consumers in six key regions. Additionally, they analyzed Duraflex’s internal costs and pricing for both their work and casual boot lines. The analysis revealed that Duraflex was positioned at the premium end of the market for both types of boots.

This case study showcases how consulting firms like Deloitte can provide essential data and analysis to help companies make informed decisions about their business strategies. It’s worth reading as it gives a glimpse into how consulting firms work and the impact they can have on a company’s success.

Hacking the Case Interview

Case interview frameworks or consulting frameworks are arguably the most critical component of a case interview. Outstanding case frameworks   set you up for success for the case while poor frameworks make the case difficult to solve.

Struggling on how to use frameworks in your case interviews? Unsure of which frameworks to use?

Don't worry because we have you covered! We'll teach you step-by-step, how to craft tailored and unique frameworks for any case interview situation.

By the end of this article, you will learn four different strategies on how to create unique and tailored frameworks for any case interview.

Strategy #1: Creating Frameworks from Scratch

• Strategy #2: Memorizing 8 – 10 Broad Business Areas
• Strategy #3: Breaking Down Stakeholders
• Strategy #4: Breaking Down Processes
• Strategy #5: Two-Part MECE Frameworks

You will apply these strategies to learn how to create case frameworks for the six most common types of case interviews.

Profitability Framework

Market entry framework, merger and acquisition framework, pricing framework, new product framework, market sizing framework.

You will also learn six consulting frameworks that nearly every consultant knows.

Porter’s Five Forces Framework

Swot framework, 4 p’s framework, 3 c’s / business situation framework, bcg 2x2 matrix framework, mckinsey 7s framework.

If you’re looking for a step-by-step shortcut to learn case interviews quickly, enroll in our case interview course . These insider strategies from a former Bain interviewer helped 30,000+ land consulting offers while saving hundreds of hours of prep time.

What is a Case Interview Framework?

A case interview framework is simply a tool that helps you structure and break down complex problems into simpler, smaller components. Think of a framework as brainstorming different ideas and organizing them into different categories.

Let’s look at an example: Coca-Cola is a large manufacturer and retailer of non-alcoholic beverages, such as sodas, juices, sports drinks, and teas. They are looking to grow and are considering entering the beer market in the United States. Should they enter?

In order for you to decide whether Coca-Cola should enter the beer market, you likely have many different questions you’d like to ask:

• Does Coca-Cola know how to produce beer?
• Would people buy beer made by Coca-Cola?
• Where would Coca-Cola sell its beer?
• How much would it cost to enter the beer market?
• Will Coca-Cola be profitable from selling beer?
• How would Coca-Cola outcompete competitors?
• What is the size of the beer market in the United States?

This is not a very structured way of thinking through the case. The questions are listed in no particular order. Additionally, many of the questions are similar to one another and could be grouped together.

A case framework would provide a structure to organize these ideas and questions in a way that is easy to understand.

A framework for this case might look like the following.

Notice that we have simplified the list of questions we had into four main categories. These broad categories are frequently called framework “buckets.” Also notice that we have grouped similar questions together under each framework bucket.

This case framework tells us what areas we need to explore in order to make a recommendation to Coca-Cola. It also clearly shows what questions we need to answer under each area.

This is the power of a case interview framework. It simplifies a complex business problem into smaller and separate components that we can tackle one at a time.

So how do you develop a case framework? The next section will reveal four robust strategies for creating unique and tailored consulting frameworks for any case interview.

Case Interview Framework Strategies

There are four case interview framework strategies you should have in your toolkit:  

When given a case interview, you will need to decide which framework strategy you want to use. Some framework strategies will be more effective than others depending on what type of case interview you get.

Therefore, choose the case framework strategy that is easiest for you given the type of case that you get.

This case framework strategy can be used for any type of case. This is the most time-consuming strategy, but yields case frameworks that are the most tailored and unique for the given case interview.

To create a framework from scratch, ask yourself what 3 – 4 statements must be true for you to be 100% confident in your recommendation. These 3 – 4 areas will become the buckets in your framework.

Once you have your framework buckets, brainstorm a few questions for each bucket that you need answers to.

Let’s return to the Coca-Cola case example in which we are asked to determine whether or not they should enter the beer market. What 3 – 4 statements must be true for us to recommend that Coca-Cola should enter the beer market?

The four major statements that must be true are:

• The beer market is an attractive market
• Competitors in the market are weak
• Coca-Cola has the capabilities to produce outstanding beer
• Coca-Cola will be highly profitable from entering the beer market

These will be the major areas or buckets in our framework.

Next, let’s add a few bullet points under each area to add more detail to our case framework.

To determine whether the beer market is attractive, we would need to know the market size, the market growth rate, and the average profit margins in the market.

To assess whether the market is competitive, we would need to know who the competitors are, how much market share they have, and if they have any differentiation or competitive advantages.

To decide whether Coca-Cola has the capabilities to produce beer, we need to know if there are any capability gaps or if there are significant synergies that Coca-Cola can leverage.

Finally, to determine the expected profitability of entering the market, we would need to know what expected revenues are, what expected costs are, and how long it would take Coca-Cola to break even.

This gives us our case framework.

You can repeat this process for any case interview that you get to create an outstanding case framework.

Strategy #2: Memorizing 8 – 10 Broad Business Areas to Make a Framework

Creating case frameworks from scratch can be quite time-consuming. Because of this, many interview candidates make the mistake of using memorized frameworks for case interviews.

Candidates will either use a single memorized framework for every case or memorize a different framework for every type of case interview.

The issue with using memorized frameworks is that they aren’t tailored to the specific case you are solving for. When given an atypical business problem, your framework areas or buckets will not be entirely relevant.

A poor framework makes the case interview significantly more difficult to solve.

Additionally, Interviewers can easily tell that you are regurgitating memorized information and not thinking critically.

Instead of creating frameworks from scratch each time, this second case framework strategy provides a method to speed up the process while still creating frameworks that are unique and tailored to the case. Additionally, you won’t need to memorize multiple different frameworks.

First, memorize a list of 8 - 10 broad business areas, such as the following:

When given a case, mentally run through this list and pick the 3 - 5 areas that are most relevant to the case.

This will be your framework.

If the list does not give you enough areas for your framework, brainstorm and add your own ideas as areas to your framework.

Finally, add a few bullet points under each area to add more detail to your case framework.

This strategy guarantees that your framework elements are relevant to the case. It also demonstrates that you can create unique, tailored frameworks for every business problem.

Let’s return to the Coca-Cola case example in which we are asked to determine whether or not they should enter the beer market.

Running through our list of memorized framework areas, the following six areas would be relevant:

• Market attractiveness : Is the beer market attractive?
• Competitive landscape : How tough is competition?
• Company capabilities : Does Coca-Cola have the capabilities to enter the market?
• Profitability : Will Coca-Cola be profitable from entering the market?
• Risks : What are the risks of entering the market?
• Strategic alternatives : Are there other more attractive markets Coca-Cola should enter?

You can pick 3 – 5 of these areas as the basis for your framework.

This strategy is a shortcut for creating unique and tailored frameworks for every business problem. Even if you and a friend used this same strategy, you both may end up with different frameworks.

That is completely fine. As long as the buckets in your framework are major areas and are relevant to the case, your case framework will be significantly better than most candidates’ frameworks.

You do not need to develop a framework entirely from scratch every time to create outstanding case frameworks. This case framework strategy can be applied to over 90% of case interviews.

For the remaining 10% of case interviews, you will need to learn and use the next two case interview framework strategies.

Strategy #3: Breaking Down Stakeholders to Make a Framework

The first two case framework strategies can be applied to over 90% of cases. However, some cases may require you to identify and focus on various stakeholders that are involved in running or operating a business.

For these cases, the primary areas of your case framework will be these major stakeholders.

Let’s take a look at an example: Your client is a non-profit blood bank. They have volunteer nurses that go to schools and companies to collect blood from donors. They then sell this blood to hospitals, which use this blood for emergency situations when a blood transfusion is required. Currently, Hearts4Lives is not profitable because they are not able to collect enough blood to sell to their hospital partners. What can they do to fix this?

This case involves many different stakeholders:

• Volunteer nurses
• Blood donors
• Schools and companies

For cases in which many different stakeholders are involved, it will be useful to look at each stakeholder and determine what each could do to address the problem.

One potential framework could look like the following:

Strategy #4: Breaking Down Processes to make a Framework

Similar to the previous case framework strategy, some cases may require you to focus on improving or optimizing a particular process.

For these cases, the primary areas of your case framework will be each major step of the process.

Let’s take a look at an example: Your client is a waste disposal company that manages a fleet of drivers and garbage trucks that go to residential homes, collect garbage, and then dump the garbage in city landfills. They have an obligation to collect each home’s garbage once a week. Recently, they have been failing to meet this requirement and are backed up with garbage disposal requests. What is causing this issue and what should they do to fix it?

For cases involving processes and efficiencies, it can be helpful to look at the different components or steps in the process.

We can think about the process of collecting and disposing of garbage in the following steps:

• Get in a garbage truck
• Drive along a designated route
• Collect garbage at each stop
• Dispose of the garbage in the landfill

Using these steps as the primary areas of our framework, we can create the following case framework:

Once you have systematically listed all of the steps in a process, you can identify the pain points or bottlenecks that are causing the issue and determine ways to improve the process.

Strategy #5: Two-part MECE Frameworks

An easy way to make a 100% MECE framework is to use a two-part MECE framework. For the first step, start with a X and Not X framework. Some examples include:

• Internal / external
• Short-term / long-term
• Economic / non-economic
• Quantitative / qualitative
• Direct / indirect
• Supply-side / demand-side
• Upside / downside
• Benefits / cost

There are probably hundreds more frameworks that follow this pattern.

These frameworks are by definition 100% MECE. Since all of these frameworks are X or Not-X, they are mutually exclusive. There is no redundancy or overlap between X and Not-X.

Together, X and Not-X are also completely exhaustive. They cover the universe of all ideas and possibilities.

The X and Not-X framework by itself is good enough for a lot of the questions you could get asked in a case interview.

If you’re asked to brainstorm ways to decrease costs, you can create a framework consisting of decreasing variable costs and decreasing non-variable costs, also known as fixed costs.

If you’re asked to brainstorm barriers to entry, you can create a framework consisting of economic barriers to entry, such as cash and equipment, and non-economic barriers to entry, such as brand name or distribution channels.

However, to take your framework to the next level and truly impress your interviewer, we have the option of doing step two.

Step two involves adding another layer of X and Not X into your framework. What do we mean by this?

Let’s say you are trying to help a city decide whether they should host the upcoming summer Olympics. You start off with a framework consisting of benefits and costs. You can take this framework to the next level by adding another layer, such as adding in short-term and long-term.

With this additional layer, your framework now has four categories: short-term benefits, long-term benefits, short-term costs, and long-term costs. This is a 100% MECE framework that enables you to think through all possible considerations in deciding whether a city should host the Olympics.

Let’s look at another example. Suppose you are trying to figure out how to reduce a company’s costs. You start with a framework consisting of variable costs and fixed costs. You can take this framework to the next level by adding another layer, such as direct and indirect.

With this additional layer, your framework now has four categories: ways to directly reduce variable costs, ways to indirectly reduce variable costs, ways to directly reduce fixed costs, and ways to indirectly reduce fixed costs. This is another 100% MECE framework.

Case Frameworks: The 6 Most Common Frameworks

There are six common case frameworks in consulting case interviews.  

Profitability frameworks are the most common types of frameworks you’ll likely use in consulting first round interviews.

A profitability case might look like this: “An electric car manufacturer has recently been experiencing a decline in profits. What should they do?”

There are two steps to solving a profitability case.

First, you need to understand quantitatively, what is the driver causing the decline in profits?

You should know the following basic profit formulas.

Is the decline in profitability due to a decline in revenue, an increase in costs, or both?

On the revenue side, what is causing the decline? Is it from a decrease in quantity of units sold? If so, is the decrease concentrated in a particular product line, geography, or customer segment?

Or is the decline due to a decrease in price? Are we selling products at a lower price? Is there a sales mix change? In other words, are we selling more low-priced products and fewer high-priced products?

On the cost side, what is causing the increase in costs? Is it from an increase in variable costs? If so, which cost elements have gone up?

Or is the increase in costs due to an increase in fixed costs? If so, which fixed costs have gone up?

Next, you need to understand qualitatively, what factors are driving the decline in profitability that you identified in the previous step.

Looking at customers, have customer needs or preferences changed? Have their purchasing habits or behaviors changed? Have their perceptions of the company changed?

Looking at competitors, have new players entered the market? Have existing competitors made any recent strategic moves? Are competitors also experiencing a decline in profitability?

Looking at the market, are there any market trends that we should be aware of? For example, are there new technology or regulatory changes? How do these trends impact profitability?

Putting all of this together, we get the following profitability framework.

Once you have gone through this profitability framework and understand both quantitatively what is causing the decline in profits and qualitatively why this is happening, you can begin brainstorming ideas to address the profitability issue.

Among the ideas that you brainstorm, you can prioritize which recommendations to focus on based on the level of impact and ease of implementation.

See the video below for an example of how to solve a profitability case using this profitability framework.

Market entry frameworks are the second most common types of frameworks you’ll likely use in consulting first round interviews.

A market entry case might look like this: “Coca-Cola is considering entering the beer market in the United States. Should they enter?”

To create a market entry framework, there are typically four statements that need to be true in order for you to recommend entering the market:

• The market is attractive
• Competition is weak
• The company has the capabilities to enter
• The company will be highly profitable from entering the market

These statements form the foundation of our market entry framework.

Note the logical order of the buckets in the framework.

We first want to determine whether the market is attractive. Then, we need to check if competition is weak and if there is an opportunity to capture meaningful market share.

If these two conditions are true, then we need to confirm that the company actually has the capabilities to enter the market.

Finally, even if the company has the capabilities to enter the market, we need to verify that they will be profitable from entering.

This is a logical progression that your market entry framework will take you through to develop a recommendation for market entry cases.

Merger and acquisition frameworks are also common frameworks you’ll use in consulting interviews.

There are two common business situations.

The first situation is a company looking to acquire another company in order to access a new market, access new customers, or to grow its revenues and profits.

Another situation is a private equity company looking to acquire a company as an investment. Their goal is to then grow the business using their operational expertise and then sell the company years later for a high return on investment. This type of case interview is called a private equity case interview .

In either of these situations, mergers and acquisition cases typically involve acquiring an attractive, successful company.

It is rare to get a case in which a company or private equity firm is looking to acquire a poorly performing company to purchase at a discount. Nevertheless, you can always clarify the goal of the merger or acquisition with the interviewer before beginning the case.

In order to recommend making an acquisition, four statements need to be true.  

• The market that the acquisition target is in is attractive
• The acquisition target is an attractive company
• The acquisition generates meaningful synergies
• The acquisition target is at a great price and will generate high returns on investment

These statements become the basis of our merger and acquisition framework.

Synergies is an area that should absolutely be included in any merger or acquisition framework. A merger or acquisition can lead to revenue synergies and cost synergies.

Revenue synergies include:

• Having access to new customer segments
• Having access to new markets
• Having access to new distribution channels
• Cross-selling opportunities
• Up-selling opportunities

Cost synergies include:

• Eliminating cost redundancies
• Consolidating functions or groups
• Increasing buying power with suppliers, manufacturers, distributors, or retailers

Pricing frameworks are used in cases involving the pricing of a product or service. To develop a pricing framework, you should be familiar with the three different ways to price a product or service.

• Pricing based on costs : set a price by applying a profit margin on the total costs to produce or deliver the product or service
• Pricing based on competition : set a price based on what competitors are charging for products similar to yours
• Pricing based on value added : set a price by quantifying the benefits that the product provides customers

Your answer to pricing cases will likely involve a mix of all three of these pricing strategies.

Your pricing framework will look something like the following.

Pricing based on costs will determine the minimum price you can realistically set. Pricing based on value added will determine the maximum possible price. Pricing based on competition will determine which price in between these two price points you should set.

In order to get customers to purchase your product, the difference between your price point and the customer’s maximum willingness to pay must be greater than or equal to the difference between your competitor’s price point and the customer’s maximum willingness to pay for their product.

New product frameworks are used to help a company decide whether or not to launch a product or service.

New product frameworks share many similarities with market entry frameworks. In order to recommend launching a new product, the following statements would need to be true:

• The product targets an attractive market segment
• The product meets customer needs and is superior to competitor products
• The company has the capabilities to successfully launch the product
• Launching the product will be highly profitable

Expanding on these areas, your new product framework could look like the following:

A comprehensive guide to market sizing questions and market sizing frameworks can be found in our comprehensive market sizing article. You can also watch the video below:

As a summary, market sizing or estimation questions ask you to determine the size of a particular market or to estimate a particular figure.

There are two different market sizing frameworks or approaches:

• Top-down approach : start with a large number and then refine and break down the number until you get your answer
• Bottom-up approach : start with a small number and then build up and increase the number until you get your answer

To create your market sizing framework, simply write out in bullet points, the exact steps you would take to calculate the requested market size or estimation figure.

Consulting Frameworks Every Consultant Knows

There are six consulting frameworks that nearly every consultant knows.

I would not recommend using these exact frameworks during a case interview because the interviewer may think you are just regurgitating memorized information instead of thinking critically about the case.

Instead use the four framework strategies that we covered earlier in this article to create tailored and unique frameworks for each case.

Nevertheless, it is helpful to review these common consulting frameworks in order to understand the fundamental concepts and business principles behind them.

Porter’s Five Forces framework was developed by Harvard Business School professor Michael Porter. This framework is used to analyze the attractiveness of a particular industry.

There are five forces that determine whether an industry is attractive or unattractive.

Competitive rivalry:  How competitive is the industry?

The more competitive an industry is in terms of number and strength of competitors, the less attractive the industry is. The less competitive an industry is, the more attractive the industry is.

Supplier power:  How much power do suppliers have?

Suppliers are companies that provide the raw materials for your company to produce goods or services. The fewer suppliers there are, the more bargaining power suppliers have in setting prices. The more suppliers there are, the weaker bargaining power suppliers have in setting prices.

Therefore, high supplier power makes the industry less attractive while low supplier power makes the industry more attractive.   

Buyer power:  How much power do buyers have?

Buyers are customers or companies that purchase your company’s product. The more buyers there are, the weaker bargaining power buyers have in setting prices. The fewer buyers there are, the more bargaining power buyers have in setting prices.

Therefore, high buyer power makes the industry less attractive while low buyer power makes the industry more attractive.   

Threat of substitution:  How difficult is it for customers to find and use substitutes over your product?

The availability of many substitutes makes the industry less attractive while a lack of substitutes makes the industry more attractive

Threat of new entry:  How difficult is it for new players to enter the market?

If barriers to entry are high, then it is difficult for new players to enter the market and it is easier for existing players to maintain their market share.

If barriers to entry are low, then it is easy for new players to enter the market and more difficult for existing players to maintain their market share.

A low threat of new entrants makes the market more attractive while a high threat of new entrants makes the market less attractive.

A SWOT framework is used to assess a company’s strategic position. SWOT stands for strengths, weaknesses, opportunities, and threats.

Strengths : What does the company do well? What qualities separate them from competitors?

Weaknesses : What does the company do poorly? What are the things that competitors do better?

Opportunities : Where are the company’s opportunities for growth or improvement?

Threats : Who are the most threatening competitors? What are the major risks to the company’s business?

The 4 P’s framework is used to develop a marketing strategy for a product. The 4 P’s in this framework are: product, place, promotion, and price.

Product : If there are multiple products or different versions of a product, you will need to decide which product to market. To do this, you will need to fully understand the benefits and points of differentiation of each product.

Select the product that best fits customer needs for the customer segment you are focusing on.

Place : You will need to decide where the product will be sold to customers. Different customer segments have different purchasing habits and behaviors. Therefore, some distribution channels will be more effective than others.

Should the product be sold directly to the customer online? Should the product be sold in the company’s stores? Should the product be sold through retail partners instead?

Promotion : You will need to decide how to spread information about the product to customers. Different customer segments have different media consumption habits and preferences. Therefore, some promotional strategies will be more effective than others.

Promotional techniques and strategies include advertising, social media marketing, email marketing, search engine marketing, video marketing, and public relations. Select the strategies and techniques that will be the most effective.

Price : You will need to decide how to price the product. Pricing is important because it determines the profits and the quantity of units sold. Pricing can also communicate information on the quality or value of the product.

If you price the product too high, you may be pricing the product above your customer segment’s willingness to pay. This would lead to lost sales.

If you price the product too low, you may be losing potential profit from customers who were willing to pay a higher price. You may also be losing profits from customers who perceive the product as low-quality due to a low price point.

In deciding on a price, you can consider the costs to produce the product, the prices of other similar products, and the value that you are providing to customers.

The 3 C’s framework is used to develop a business strategy for a company. 3 C’s stands for customers, competition, and company.

The business situation framework was developed by a former McKinsey consultant, Victor Cheng, who added a fourth component to this framework, product.

Both of these frameworks are used to develop a business strategy for a company in a variety of situations, such as market entry, new product launch, and acquisition.

There is another similar framework called the 4C framework that expands upon the 3 C's. The 4C framework stands for customer, competition, capabilities, and cost.

The BCG 2x2 Matrix Framework was developed by BCG founder Bruce Hendersen. It is used to examine all of the different businesses of a company to determine which businesses the company should invest in and focus on.

The BCG 2x2 Matrix has two different dimensions:

• Market growth : How quickly is the market growing?
• Relative market share : How much market share does the company have compared to competitors?

Each business of the company can be assessed on these two dimensions on a scale of low to high. This is what creates the 2x2 Matrix because it creates four different quadrants.

Each quadrant has a recommended strategy.

• Stars : These are businesses that have high market growth rate and high relative market share. These businesses should be heavily invested in so they can continue to grow.
• Cows :   These are businesses that have low market growth rate, but high relative market share. These businesses should be maintained since they are stable, profitable businesses.
• Dogs :   These are businesses that have low market growth rate and low relative market share. These businesses should not be invested in and should possibly even be divested to free up cash for other businesses.
• Unknown : These are businesses that have high market growth rate and low relative market share. The strategy for these businesses is not clear. With enough investment, these businesses could become stars. However, these businesses could also become dogs if the market growth slows or declines.

The McKinsey 7S Framework was developed by two former McKinsey consultants, Tom Peters and Robert Waterman. The 7S Framework identifies seven elements that a company needs to align on in order to be successful.

These elements are:

• Strategy : The company’s plan to grow and outcompete competitors
• Structure : The organization of the company
• Systems : The company’s daily activities and processes
• Shared values : The core beliefs, values, or mission of the company
• Style : The style of leadership or management used
• Staff : The employees that are hired
• Skills : The capabilities of the company’s employees

The A.I. Boom Has an Unlikely Early Winner: Wonky Consultants

Rattled by tech’s latest trend, businesses have turned to advisers at Boston Consulting Group, McKinsey and KPMG for guidance on adopting generative artificial intelligence.

• Share full article

By Tripp Mickle

Tripp Mickle has been writing about technology since 2016.

After ChatGPT came out in 2022, the marketing team at Reckitt Benckiser, which makes Lysol and Mucinex, was convinced that new artificial intelligence technology could help its business. But the team was uncertain about how, so it turned to Boston Consulting Group for help.

Reckitt’s request was one of hundreds that Boston Consulting Group received last year. It now earns a fifth of its revenue — from zero just two years ago — through work related to artificial intelligence.

“There’s a genuine thirst to figure out what are the implications for their businesses,” said Vladimir Lukic, Boston Consulting Group’s managing director for technology.

The next big boom in tech is a long-awaited gift for wonky consultants. From Boston Consulting Group and McKinsey & Company to IBM and Accenture, sales are growing and hiring is on the rise because companies are in desperate need of technology Sherpas who can help them figure out what generative A.I. means and how it can help their businesses.

While the tech industry is casting about for ways to make money off generative A.I., the consultants have begun cashing in.

IBM, which has 160,000 consultants , has secured more than $1 billion in sales commitments related to generative A.I. for consulting work and its watsonx system, which can be used to build and maintain A.I. models. Accenture , which provides consulting and technology services, booked $300 million in sales last year. About 40 percent of McKinsey’s business this year will be generative A.I. related, and KPMG International, which has a global advisory division, went from making no money a year ago from generative-A.I.-related work to targeting more than $650 million in business opportunities in the United States tied to the technology over the past six months.

How AI-driven SOC tech eased alert fatigue: Case study

Alert fatigue is real, and it can cause big problems in the soc. learn how generative ai can improve security outcomes and reduce analysts' frustration in this case study..

• Alissa Irei, Senior Site Editor

Cybersecurity executive Jonathan Fischbein had a problem to which his peers can likely relate: too many security alerts and too few security operations center analysts.

"We have a tight budget," said Fischbein, CISO at cybersecurity software provider Check Point. "I'd say that, in the SOC, we were lacking between 30% and 40% manpower."

Without enough staff to respond to the constant flood of security alerts coming from the organization's SIEM platform, conditions were ripe for disaster. "If you have an alert that you're not addressing, that alert might become an incident," Fischbein said. "And that is something that, as the CISO, I don't want."

AI unseats legacy SOAR

With the aim of reducing his team's alert fatigue and improving Check Point's security posture, Fischbein began exploring automation platforms. Feedback from fellow CISOs and CIOs led him to bypass legacy security orchestration, automation and response ( SOAR ) products in favor of a hyperautomation platform from startup Torq.

"We really liked the fact that the UI is graphical and that there are a lot of workflow automation templates," Fischbein said, adding that the platform's design centers SOC analysts' experience to make their jobs easier.

Check Point initiated a proof of concept . Within a few days of the trial's inception, Fischbein said, Torq had deployed more than two dozen AI-driven playbooks, automating responses to some of the organization's most repetitive security alerts.

Importantly, the Torq technology also integrated easily with Check Point's existing infrastructure and security stack, ingesting and analyzing data from a variety of systems and tools. "It fit like a glove," Fischbein said.

AI goes to work in the SOC

Today, Torq's technology -- now known as HyperSOC -- investigates, triages and remediates many of Check Point's internal security alerts without any human intervention. If an alert meets certain parameters based on organizational security policies, the platform autonomously takes relevant predefined steps, such as initiating an MFA challenge or locking out a suspicious user.

"We can react automatically to problems before they become security incidents," Fischbein said.

When events are potentially critical or complex, HyperSOC flags them for analyst oversight or intervention and offers suggestions for next steps.

According to Torq, organizations can also train the generative AI-driven SOC platform to consider contextual factors in its decision-making -- for example, requiring confirmation from a human operator before locking the CEO's account.

Natural language processing speaks up

Fischbein compared Torq's HyperSOC to a Swiss Army knife in that it helps address diverse security events of varying severity.

Some of that flexibility is thanks to the technology's large language model capabilities, which enable it to ingest material written in natural language -- ranging from proprietary in-house playbooks to documentation of industry frameworks, such as Mitre ATT&CK -- and cross-reference it during event triage, investigation and response efforts.

In cases requiring human intervention, the platform also uses natural language to summarize its own workflows, present relevant data and offer next-step recommendations. This helps human analysts make more efficient and informed decisions, minimizing the time and effort they spend on tedious and manual investigative tasks during active incidents.

AI is a SecOps tool, not a panacea

According to Fischbein, Torq's AI-driven SOC platform has successfully increased efficiency and reduced alert fatigue among Check Point's security analysts. But that's not to say he considers his staffing woes solved.

"In our organization, we're talking about almost 7,0000 users in about 80 different locations worldwide. The problems are endless," he said. "If I increased my SOC staff by 40%, I would still have problems."

In other words, the never-ending battle between SecOps teams and attackers continues -- albeit with AI-driven SOC technology potentially giving the good guys an edge.

"It's a cat-and-mouse game," Fischbein said. "And, with Torq, we can catch the mouse more easily."

Prediction: The future of Customer Experience

McKinsey & Company Partner Onur Mumcu had a talk with McKinsey & Company Senior Partner Kevin Neher to understand why survey results do not properly account for the real customer experience and what companies should do to solve this problem. This podcast was recorded at the Harvard Business Review’s live webinar. The following transcript was edited for clarity.

Podcast Transcript

Onur Mumcu: We have a McKinsey Senior Partner, Kevin, here with us. Welcome, Kevin. So, Kevin and I have known each other for, almost 15 years now. When I was working for our Chicago office in the US and since then, he started to work for our Denver office in the US and now he is the global co-leader of McKinsey's customer experience efforts. And in this session, we would like to talk about the future of customer experience with Kevin. Today, customers are becoming more sophisticated and customer experience has become very important for businesses all around the world. Our future of customer experience research reveals that improving the customer experience increases sales revenues by two to seven percent and profitability by one to two percent. And in addition to this, the overall shareholder returns increase by seven to 10 percent with better customer experience. And we also saw that during COVID, seventy five percent of consumers changed their buying habits, and 40 percent switched brands retailers. The future of growth will be experience-led and customer-centred. And unfortunately, many organizations fail to see that, and despite their efforts, many still struggle to understand what really drives the customer experience. Today, Kevin, we would like to get some insights from you, and my first question is, what's going wrong in terms of customer experience according to your observations? In the report, you talk about the survey results do not properly account for the real customer experience and the companies are trying different methods. Can you elaborate a little bit on that one?

Kevin Neher: Absolutely. Thank you, Onur. Thank you HBR for having us. It's a great pleasure to talk to everyone today. To your question on our survey-based systems, we think of customer experience, a lot of the work that customer experience groups do today is around getting feedback from customers. And this happens across sectors, right? Whether it's patient experience, customer experience, client experience, consumer experience, everyone is looking to get feedback, and this has been a long-standing method for over 20 years. People have been sending out emails or recently through texts or apps or other avenues, but it's virtually stayed the same.

Onur Mumcu: When you get calls from the customer, the call centres.

Kevin Neher: Yes, you get outbound calls and all kinds of things that will hassle you. But this has really stayed the same, right? This hasn't evolved really in 20 years, except for some minor details on the software. And what we're seeing is that it doesn't reach everyone. Segments are not answering in the same way. People are overloaded with these emails and calls and reach outs of all sorts. In addition, it's got a big lag in it. In the world that's speeding up. The speed of everything is getting faster, digital and communication, and we just move so much quicker. Yet we're still have this huge lag. And when people receive surveys, fill out surveys and companies and organizations analyse those surveys. And so, you have this lag in it as well. Third, you also don't get the root causes out of what people tell you. You get symptoms. People say the line was long, but they don't. You don't know why the line was long. You have to go do work to then figure that out. And then finally, there's one pitfall in all my customer experience work that I see companies make is they don't link customer experience to value, and surveys do not help with this problem. They make it very hard to actually understand what my return is for investing and fixing some of these things. It just doesn't come from survey work. And so, we've kind of taken on those four challenges to say, hey, how can we do this better? How can we actually get more out of customer experience? And maybe surveys aren't the answer anymore.

Onur Mumcu: What is the answer, Kevin? What do some of the companies do? You know, what are other methods, other than the surveys to measure customer experience?

Kevin Neher: Absolutely. There is an explosion of data out there. That's no surprise to anyone and you see other functions taking that on, right? You see, maintenance organizations using data to get predictive on what is going to fail and getting ahead of it, right? You see revenue and pricing organizations using all sorts of data to try to understand how to adjust and where to price better and get a better return. Customer experience just hasn't moved in this direction, and that's what's been missing. We have all kinds of data out there, yet we're still acting like it's 20 years ago and we need to send emails to people. So, take advantage of all the data and we think about data. Think about it in three big buckets. Think about it in customer data, things like demographic data, all kinds of things describing the customer who they are, what they do and where they're headed. Think about operational data? So, all the things that are out there in the experience, right? I don't need to have you fill out a survey to tell me that the airline lost your bags, right? I know whose bags they lost every day if I'm an airline, and I should be doing something about it before I actually get surveyed. That's a problem. And then financial data, which links back to that link to value understanding. The history of a customer and what their potential is very important than linking it back to the investment case for how we're going to go fix the experience. It's about data and then using it to put machine learning, put more predictive algorithms on top of that so that I can address the entire customer base, not just the ones who fill out a survey.

Onur Mumcu: So, Kevin, on that one, I can clearly see the demographics data and also the operational data. But there are certain experiences where you cannot measure with operational data, right? Let's take your airline example. Like I fly with, let's say, Turkish Airlines, Pegasus, or Lufthansa, and I had an issue with a flight attendant or, I didn't like the food on the plane, right? And you probably do not measure it. Similar to your losing the back example, right? What do you do in these cases? How do you measure the customer experience in those cases?

Kevin Neher: So, a couple of thoughts. First off, we're not saying get rid of surveys all together, getting some feedback as part of that customer data set. It’s just don't make it the top of the pyramid. Make it an input into the system, right? Because it is valuable for what it is, and it does help you make the connection. So, you do get good feedback. People do still give you feedback, but just don't make it the top of the pyramid. That's kind of point number one. Point number two is you might need to add some data sources, some listening posts, some different ways together. So, in your example, having a way for flight attendants to quickly rate the meal based on what customers say or the amount of food that's not eaten gives important feedback into the system and the product group or whoever is designing that meal and that piece, right? And that's about now adding data to the thing. And then maybe third, we've talked a lot about the quantitative set of customer experience, and that is how you get into prediction. But designing great experiences is still about human centred design. And that's a whole another big part of customer experience that has really evolved in the last 10 years. Where you really are not doing customer experience if you're not bringing human-centred design into your processes. And so that is how you then take action on what you've learned, maybe in some of the quantitative data on what to go fix. And that's an important basis for how it all comes together.

Onur Mumcu: Very cool. We are not very open about our clients and the type of work we do. But without breaching that confidentiality, can you share some of the good examples, good companies and some of the cool stuff that they've been doing on this one? So, we can also get a bit understanding of this.

Kevin Neher: Well, you're right, we don't usually talk about individual companies, but I think it's important to look out there at some of the sectors that have really had a rise in the last few years and what they're doing about it, right? So first off, if you think about who the winners of the last two years have been, it is a lot of companies that were ahead of the digital curve. Companies that really brought an integrated experience and you see this, whether it's streaming services, right? I'm sure you have examples in Turkey as well. But whether it's Netflix or others, right, who really invested in that experience and have built the content and been able to use data to figure out which ones, how to invest, where to invest and continue to improve that. You also see it in even banking, right? Banking used to be a very stodgy old industry, especially in the U.S. not sure around in Turkey, but the integration and the move to digital and really rethinking experiences. So, the account opening experience, right? That used to be something that took many forms and all kinds of visits to a retail branch. But now you can do it in seconds, literally.

And things like that, where they appreciate what was required was, yes, you want security and trust, but you also want speed. And that has changed. And I think it's important to realize that what we're seeing is that it's B2B companies. It's companies that serve farmers, companies that serve businesses, companies that serve all these other industries are now the ones trying to catch up because customer experience is part perception. Meaning that when my expectations change, then I change how I view everybody. So, if Amazon is going to deliver me a package in 24 hours or 48 hours, and now I'm at a railroad and I have customers who I'm shipping cars of sugar for their candy factory. Guess what? Those same people on the other end are buying Amazon as well, and now they're wondering why their train cars can't get there in 48 hours, or at least why they can't know where they are on the system. And changing expectations that really have set customer experience onto a faster speed and why it's really mattering so much more in how people make choices.

Onur Mumcu: So, let's say I am a chief customer experience or chief consumer officer or even a CEO, right? And I hear this and I get very interested. Where do I start? I mean, do I start with collecting a bunch of data and asking for my teams, and tell “OK, now please use this”. Or should I think about what kind of use cases or what kind of questions I need to ask and then start getting the data? Because we also hear from our clients that collecting data is a problem and processing data is another problem. Finding the right people to do all this work is another problem. So, what would you do if you were an executive on this one? And how can you measure the value or the return on investment on this one?

Kevin Neher: Yes, for sure. Let's set it up. It's a three-step approach to getting to value in customer experience. So, you've got to set an aspiration. Then you have to invest in the new experiences and then you have to have capabilities to go after it. But let's talk about that first one for a second, because that's your question is really about where do we start? Well, in talking about the senior executives, it does have to start with them. Customer experience is fundamentally a cross-functional problem. And what I mean by that is most great companies, have done well over time. These great companies have done so by getting functionally excellent. And customer experience actually cuts across those. Customers don't care who's in finance department or who's in marketing or who's in operations, right? They see their journeys. They need to accomplish stuff. They need to set up that account. They need to get an issue resolved. They need to make a payment. And those don't often align with internal structures. And a company first say, we really want to tackle this. We have to have cross-functional alignment and it does often role all the way up to the CEO because that's the person who can really help push it and drive it and get alignment. So, you do have to have that alignment. Then the second piece is you do need to know your starting point, right? One of the first places that we start with is understanding this current satisfaction and the current importance of the different experiences.

So, just to double click on that for a brief second. What that means I need to know how I'm doing on different journeys. So, taking a journey-based view, but I also need to know what matters to the customer more. What we find is that often it's only two or three journeys out of eight or nine that really drive 70 percent of the experience. So, invest in those first, because getting to your point, we know the ROI is going to follow. Then third, coming back to one of the points from earlier, you have to get after the link to value. You have to start with an aspiration. I don't know the Turkish business landscape well. But in the U.S. and a lot of the multinational corporations’ CFOs are stronger than ever. Finance organizations want a business case. They want to see that solidly in numbers. And if you don't have those six months down the road, your program, your initiative is likely on the chopping block if you can't show tangible value. So, we have to start in that first piece around setting. The aspiration has to include a real link to values that you can show with a fact base. What is the potential ROI from customer experience? And be ready to hang your hat on that because that business case then helps to build the longevity of the program.

Onur Mumcu: Thank you. When the companies are starting these programs what are the typical challenges that they face? Is it more on the technology side, on the talent side or on setting the aspiration side? Where do you think the real challenge lies for the organizations?

Kevin Neher: Yeah, let's assume you get the alignment which we just talked about. Because that is a big one to get going. The two that often hold back people from kind of launching from really getting going around data and people and skill sets. So, let's talk about that for a second. First one is data. Just like I talked about, great organizations are functionally excellent, so is their data. That means, you have a lot of data silos out there. You have a lot of data that have grown up and even been protected by different parts of the organization. And you do have to think about how you engineer some setup, some data lakes, data architecture to bring some of that together around those that customer data, operational data and financial data. But we're not talking about is a big data project, though this is not about a big data mart, a big data warehouse. This is about a flexible data layer that allows you to pull and do that. Often, it's tokenized. We do a lot of work with GDPR and other sort of data privacy pieces to make sure that it's all able to be used, but that's important. It's being able to go after the data and bring it together and having permission. So that's a big thing because again, data is just as separated as sometimes people are or more so. That's one big challenge to take on early and understand that it's a lot easier to say what you want to do with the data than it is to go get it.

And then the second one is on people and skill sets. I mentioned human-centred design earlier, right? We find that companies need to build their design capabilities. They need to have designers part of each journey redesign. They need to have that skill set data science. They need to be able to have people who can help see through the data and have the data work for them rather than having too many people off doing different types of analysis. You need one source of truth in data science can help kind of build that capability, and then you need some strong athletes. This might sound funny coming from someone who leads customer experience globally and works a lot of organizations, but I don't believe necessarily in see experts in an organization. I think it's such an important problem. You want your highest potential people; you want your people who you want to see build different capabilities to work in customer experience as almost to rotation. Give them a project, give them a journey ownership, something that does cut cross functionally because that's only going to serve them better as they take on more in different roles. But you need some strong athletes that know how to work across functional lines that don't necessarily just see themselves as an expert. So those two things are usually the biggest challenges both the data and then also those resources of people and skill sets to bring into it.

Onur Mumcu: So, if I am the CEO of an organization in any industry and if I want to start what would be your advice to me? What should I do first thing in the morning?

Kevin Neher: Yes. This is a strategic choice. Are you going to win with the customer? That is where the commitment starts. Is this going to be part of your differentiation, is this going to be part of how you win in the future? As industries change, as trends change, as all sorts of different things around us go on and on, are you going to set your organization up for success by differentiating with a better experience? Customers for sure, you need to be thinking about your employee experience, too, by the way. We're not going to go into deep on that right now, but the experience I quite like, are you going to differentiate on that? You have to make that commitment as a CEO because it is going to be one of the top two or maybe three things that you do this year and you're going to make a commitment to that. And this is not a quick win type of move, this is a strategic choice.

Onur Mumcu: Thank you, Kevin. I mean, this was very insightful, and I'm sure a lot of our listeners today already started thinking about the customer experience and how they can implement it in their organizations going forward as well. Always a pleasure having you.

After Supreme Court ruling, judge considers Trump's immunity claim in classified docs case

Donald Trump is seeking to build on his Supreme Court victory, which provided immunity from criminal prosecution for his official acts as president, by asking judges in his federal classified documents case and in his New York hush money conviction to throw out all of those charges.

U.S. District Judge Aileen Cannon postponed deadlines Saturday to debate evidence in the classified documents case and instead asked for written arguments about Trump’s immunity in the next two weeks.

Trump’s lawyers asked Cannon on Friday to halt all action in the classified documents case until she rules whether the charges are valid.

New York Judge Juan Merchan postponed sentencing Trump for his hush-money conviction of 34 counts of falsifying business records, which had been scheduled for Thursday, until September.

When the Supreme Court formally returns the election-interference case to U.S. District Judge Tanya Chutkan, she must weigh which charges are still valid to prosecute.

Neither Justice Department special counsel Jack Smith nor Manhattan District Attorney Alvin Bragg has responded to the Supreme Court’s decision yet.

Trump’s lawyers, Todd Blanche and Christopher Kise, have argued the high court’s ruling means each of the judges will have to determine which conduct is official or unofficial – and not use any official conduct as evidence for charges against unofficial conduct.

Here is where the cases stand:

Supreme Court orders 'close analysis' of whether Trump conduct was unofficial

The reason for uncertainty about criminal charges against Trump is because no former president has ever been charged before and the Supreme Court hadn’t ruled on whether they could be.

Until July 1. That’s when Chief Justice John Roberts wrote for a 6-3 majority that former presidents can’t be tried for their official acts, but could potentially be charged for unofficial acts.

The ruling said presidents discussing policy with executive agencies can’t even be questioned about their motives. This ruled out charges involving Trump urging his acting attorney general to pursue allegations of election fraud with officials in swing states.

But the ruling left open the possibility of charges dealing with Trump’s recruitment of fake presidential electors to support him in states President Joe Biden won. Roberts wrote that determining whether Trump's pressure on then-Vice President Mike Pence "requires a close analysis of the indictment’s extensive and interrelated allegations."

“The President is not above the law,” Roberts wrote. “But under our system of separated powers, the President may not be prosecuted for exercising his core constitutional powers, and he is entitled to at least presumptive immunity from prosecution for his official acts."

Trial judges must now determine whether Trump’s conduct for the various charges was official or unofficial.

Judge postpones filings in classified documents case to study Trump's immunity claim

Trump was charged with retaining national defense records and conspiring to hide them from government authorities until FBI agents seized them during a search of Mar-a-Lago, his Florida estate, in August 2022.

Prosecutors have noted the entire case involves conduct after Trump left the White House in January 2021. Smith's team office said Trump did not have legal authority to designate secret national security documents as personal records and send them to his private home. But Trump’s lawyers have argued his decision to ship the documents to Mar-a-Lago was an official act.

In an order Saturday, Cannon scrapped a Monday deadline for Trump to disclose his experts and Wednesday deadlines for prosecutors and defense lawyers to share more evidence in the case.

Instead, Cannon set a deadline July 18 for Smith to respond to Trump’s request for immunity. Trump will have until July 21 to respond.

Cannon hasn’t set a date for a hearing, but said she could still collect more evidence.

Trump’s lawyers want Cannon to only move forward on two issues in the case: Smith's request for a gag order preventing Trump from making comments that could incite threats against FBI agents working the case, and whether Smith was properly appointed to his job as special counsel.

In the Supreme Court’s ruling on immunity, Justice Clarence Thomas, wrote  a concurrence  questioning Smith's appointment, even though that wasn't at issue in the case and many special counsels have been previously appointed under similar circumstances.

Judge in federal election interference must also determine unofficial conduct

The Supreme Court hasn’t formally returned Trump’s election-interference case to Chutkan, under what is called a “mandate,” which might not happen until Aug. 2.

“The judgment or mandate of this Court will not issue for at least thirty-two days,” Supreme Court clerk Scott Harris wrote July 1 to the D.C. Circuit Court of Appeals.

Chutkan will have to review which charges – if any – can go to trial once she gets the case back.

New York sentencing postponed because of potential immunity

Merchan previously postponed sentencing Trump in the hush-money case, which had been scheduled Thursday, until Sept. 18.

But that’s only if necessary. Merchan plans to decide Sept. 6 whether Trump is immune from the charges, even though his case involves state charges and the Supreme Court was reviewing federal charges.

Trump was convicted May 30 of falsifying records to hide his reimbursement to private lawyer Michael Cohen, who paid $130,000 to silence porn actress Stormy Daniels about alleged sex with Trump before the 2016 election.

The financial arrangements between Cohen and Daniels happened before Trump was elected president. But his series of 11 payments to Cohen – through his private company – happened the first year of his presidency.

Merchan previously ruled that Trump filed an immunity argument in the case too late to be considered.

Unexpectedly, the solubility of CeO 2 nanoparticles (NPs) at 25 °C does not depend on particle size, but is significantly affected by the sample's thermal pre-treatment. The classical interpretation of NPs' solubility proposed by the Gibbs–Thompson or Kelvin equations fails to describe the experimental data on CeO 2 solubility obtained in this study. Thermal treatment did not change the samples' morphological characteristics, while slightly affecting NP hydroxylation and local crystallinity. The differences in the solubility of dried and non-treated CeO 2 particles were most noticeable at pH < 4, and dissolved cerium concentration was much lower in the case of the dried sample. After prolonged storage (up to 4.5 years) of CeO 2 NPs in aqueous media, the solubility of dried samples gradually increased, while for non-treated samples it remained unchanged. Based on the example of CeO 2 , the dissolution laws of other less soluble nanomaterials should be reconsidered.
