Answering essay questions in exams

Writing an essay in an exam is similar in many ways to writing an essay for an assignment: It needs to be clearly structured, and your ideas need to be linked and supported by evidence.

Essay questions in exams

• Read the question through carefully to make sure you are answering what has been asked.  Missing one part of a question can cost you a lot of marks.
• Make a quick plan of the points you want to include in your answer.
• Use essay structure: introduction, points, conclusion.  But if you run out of time, it can be a good idea to write notes.
• Get right to the point from the beginning.  Use the words from the question to write your first sentence. For example:

Question: What do you think is the most important intercultural communication issue in New Zealand? First sentence: At present in New Zealand the most important intercultural communication issue is...

• Remember to include one idea per paragraph, and to begin each paragraph with a clear topic sentence.
• Make sure your writing is legible.
• Grammar, punctuation and spelling are not as important as in an assignment but should still be of a good standard.

Answering case study questions

Exam questions that ask you to anlayse case studies (also called scenarios) are usually designed to test your ability to relate theories and concepts to real-world situations.

Preparing for case studies before the exam:

• Start by identifying the theories and concepts covered in your course.  Organise and review the information you have on these theories/concepts so you understand them.
• Practice reading case studies and identifying relevant information. It's probably useful to practice doing this with a time limit as you will have one in your exam.
• Practice relating concepts and theories to real-world situations: ask lecturers and check textbooks for practice examples. It is also worth checking past exams for your course to see if there are examples of case study questions.

During the exam

• Take time to plan: Have a clear idea of how much time you have to answer the question. Then plan to spend some time reading the exam question, the case study and planning your answer. Take time to make sure you have understood the case study and know what the exam question is asking you to do:
• Read the exam question(s)
• Then skim read the case study to get the general idea. Highlight or underline key points
• Reread the question to make sure you understand it and to focus your attention when you reread the case study.
• Reread the case study carefully. Make a note of any ideas that you think of.
• Answer the question linking relevant theories and concepts to specific information from the case study. Usually you will need to write your answers in clearly formed paragraphs which have a clear topic that is well-supported with evidence and examples.
• Instead of simply describing or restating information from the case itself, use specific details or examples to support the points you are trying to make. This is where you link theory to the facts from the case study.

A case study interview isn’t your average interview. While most interviews ask you to give examples of how you use your skills on the job, in a case study interview, you’ll use those skills in front of the interviewer to solve a real-life problem.

It’s like auditioning for the school play. But instead of showing you can sing and dance, you’re using a case interview to show how you provide innovative solutions to pressing business problems. Not sure how to get ready for this kind of interview? We’ve got you covered. This guide explains how to prep for a case study interview.

Case studies are used across a variety of industries — everything from business to medicine. They are an in-depth examination, analysis, and critique of a real-world scenario the company experienced. People discuss the situation and explore what they learned while forming new solutions to try when they face a similar situation in the future and hope to improve their performance.

For example, doctors and nurses use case studies to improve how they diagnose and treat patients. Using real patient information, the medical team analyzes the case to see what the team may have missed and why they missed it. Learning from these errors helps the team better prepare for similar cases in the future to improve patient care.

While many industries use case studies to iterate and improve their performance, not every company uses case study interviews. This type of interview is very common at consulting companies (no matter what kind of consulting it is). But it’s not unusual for companies outside of consulting to use case interviews for marketing or operations roles.

In a case study interview, you’re given a real-world situation the company has faced and are tasked with analyzing it and suggesting a course of action.

Avg. Time: 5-6 hours

Skills you’ll build: Prioritizing, planning, data analysis, error spotting, communication, strategic thinking

Businesses use case study interviews to assess your abilities in real-time. While you’ll probably draw on a variety of skills, most case study interviews assess:

• Strategic thinking
• Analytical skills
• Common sense

The advantage of a case study interview is that the interviewer can evaluate your ability in each of these areas and see how you’ll actually use them on the job.

What Is a Fit Interview?

Some people use “case study interview” and “fit interview” interchangeably. While a fit interview and a case study interview both ask behavioral interview questions , they are not the same thing.

A case study interview assesses your ability to do the job. It primarily evaluates how you approach business problems and use your skills to solve them. A fit interview is about company culture fit. The interviewer asks questions that assess how well you’ll fit into the company, like asking you questions about what motivates you or how you lead .

Fit and case interviews are important parts of the evaluation process. Getting the job done is just as critical as getting along with coworkers and supporting the company’s mission. Depending on where you interview, you may have one fit interview and one case study interview, or the fit interview may be a smaller part of the case study interview.

What You’ll Learn in a Case Study Interview

A case study interview allows the hiring manager to see your skills in action and how you approach business challenges. But it also teaches you a lot about the company (even if you’re doing most of the talking).

In a sense, you’re behaving as an employee during a case study interview. This gives you a peek behind the curtain, allowing you to see the company’s inner workings, like how they approach business problems and what they expect from you and your performance.

For example, you may offer a novel approach to solving a problem during a case interview. How does the interviewer react to it? Are they impressed? Surprised? Is there a scowl or frown on their face? Their reaction gives you insights into how the company will likely receive your solutions.

Avg. Time: 2 hours

Skills you’ll build: Critical thinking, creativity, brainstorming

Depending on the specific company, you may have the case study interview questions in advance, but you may not. Whether you do or don’t, here’s how to prepare for a case study interview.

Conduct Deep Research

Good interview prep for any interview means researching the company. That includes things like learning more about the company’s mission and the challenges the industry faces. But when you’re preparing for a case study interview, your research needs to go deeper. 

When you answer a case study question, your answer has to be specific to the company’s clients or business objectives. For example, if you’re interviewing for a role in strategy consulting , your answer shouldn’t focus on aspects of human resources consulting (unless it’s particularly relevant).

Your research needs to include the kinds of clients the company works with and what types of problems the company solves. For example, the company may only consult for Fortune 100 companies that need accounting advice. Keep these facts in mind as you prepare for the interview.

Case Study Interview Formats

There are four types of case study interview formats:

• Candidate-led: The interviewer asks you a specific question (or gives you a prompt), and you walk the interviewer through a detailed answer.
• Employer-led: The interviewer leads you through a series of specific (and predetermined) prompts and questions, no matter your answers.
• Presentation: You’re given a problem in advance to create and present a detailed case study.
• Video: Similar to a presentation case study interview, you’ll create a video presentation of the case study.

Most companies will tell you in advance which style of case study interview you should prepare for. But if they don’t, reach out to your recruiter or check the company’s website. Many include the essential details you need to prepare for the case study interview.

Seek Out Company-Specific Tips

Speaking of companies and their websites, not only do many companies that use case study interviews tell you the format, they often include helpful tips and tricks to help candidates prepare. This includes what to expect, what the company is looking for skill-wise, and what kinds of responses they want. They may even have a few practice questions and videos you can use to help you prep.

Unlike other common interview questions , it’s not as easy to prepare an answer to case study interview questions. Even though you know it’s a case study interview, you don’t necessarily know the specifics of the case or what problems you’ll be asked to solve.

Cybersecurity

Work through a case experience in this free course from PwC Switzerland. Create a pitch, conduct a risk assessment, and explain your findings.

Skills you’ll build: Risk management frameworks, cause analysis, risk impact assessment, system security

That said, it’s likely your case study interview questions will cover one or several of these concepts:

• Entering new markets
• Increasing profits
• Cutting costs
• Turnarounds
• Mergers and acquisitions
• Pricing strategy
• Developing new products
• Industry analysis
• Competitive response

While there are many ways to answer case study interview questions, a few basic prep tips can help you get ready for every question.

In addition to what you usually bring to a job interview , make sure you bring a notepad and pen or pencil to a case study interview. Taking notes will help you better understand the questions and formulate your answers. It also gives you a place to calculate numbers and figures if you need to. Not every case study interview allows calculators, so you’ll need to be ready to do your calculations manually.

Ask Specific Questions

As you’re working through the case study, you can and should ask any clarifying questions you need. The interviewer wants to hear specific, detailed answers that solve the problem. So, whenever you’re unclear, ask a follow-up question to not only get what you need but to give the interviewer what they need. 

That said, your question(s) should be very specific. You need to verify exactly what the interview is asking so you can create an appropriate answer. Say the interviewer gives you a broad question: The client’s revenue is falling. How do you help them increase it? You can follow up with a very specific question or two to make sure you understand what the interviewer is asking:

You’re asking how I would help the client raise revenue, correct? Are you also asking how I would help them increase their profit and cut costs?

Talk Them Through It

A big part of the case study interview is seeing you in action. However, in this case, “see” really means “how you think.” Since the interviewer can’t hear your inner monologue, you’ll need to practice thinking out loud.

While the interviewer wants to hear your solution, they also want to hear how you got there. That means talking through your entire thought process. Instead of saying, “I’d do X,” you have to explain how you arrived at your decision while you’re getting there.

Because not everyone thinks out loud, it may feel unnatural to you, and you likely won’t be expected to do it on the job. But it’s crucial to practice this skill — and it is a skill — because the interviewer is expecting you to do it in a case study interview.

Case Study Interview Questions About the Customer's Business

Knowing the customer's business is an excellent way of setting the tone for a case study.

Use these questions to get some background information about the company and its business goals. This information can be used to introduce the business at the beginning of the case study — plus, future prospects might resonate with their stories and become leads for you.

• Would you give me a quick overview of [company]? This is an opportunity for the client to describe their business in their own words. You'll get useful background information and it's an easy prompt to get the client talking.
• Can you describe your role? This will give you a better idea of the responsibilities they are subject to.
• How do your role and team fit into the company and its goals? Knowing how the team functions to achieve company goals will help you formulate how your solution involves all stakeholders.
• How long has your company been in business? Getting this information will help the reader gauge if pain points are specific to a startup or new company vs. a veteran company.
• How many employees do you have? Another great descriptor for readers to have. They can compare the featured company size with their own.
• Is your company revenue available? If so, what is it? This will give your readers background information on the featured company's gross sales.
• Who is your target customer? Knowing who the target audience is will help you provide a better overview of their market for your case study readers.
• How does our product help your team or company achieve its objectives? This is one of the most important questions because it is the basis of the case study. Get specifics on how your product provided a solution for your client. You want to be able to say "X company implemented our solution and achieved Y. "
• How are our companies aligned (mission, strategy, culture, etc.)? If any attributes of your company's mission or culture appealed to the client, call it out.

How many people are on your team? What are their roles? This will help describe key players within the organization and their impact on the implementation of your solution.

Case Study Interview Questions About the Environment Before the Purchase

A good case study is designed to build trust. Ask clients to describe the tools and processes they used before your product or service. These kinds of case study questions will highlight the business' need they had to fulfill and appeal to future clients.

• What was your team's process prior to using our product? This will give the reader a baseline to compare the results for your company's product.

• What were the major pain points of your process prior to using our product? Describe these obstacles in detail. You want the reader to get as much information on the problem as possible as it sets up the reasoning for why your company's solution was implemented.
• Did our product replace a similar tool or is this the first time your team is using a product like this? Were they using a similar product? If so, having this information may give readers a reason to choose your brand over the competition.

It's also great to illustrate any unique challenges the client had. This better explains their situation to the reader.
• Did you have to make any changes you weren't anticipating once you became a customer? Readers of your case study can learn how switching to your product came with some unexpected changes (good or bad) and how they navigated them. If you helped your client with troubleshooting, ask them to explain that here.

• Who on your team was involved in the buying process? This will give readers more background on the key players involved from executives to project managers. With this information, readers can see who they may potentially need to involve in the decision-making process on their teams.

Case Study Interview Questions About the Customer's Business Case

Your case study questions should ask about your product or solution's impact on the customer's employees, teams, metrics, and goals. These questions allow the client to praise the value of your service and tell others exactly what benefits they derived from it.

Case Study Interview Questions About the Buying Team and Internal Advocates

See if there are any individuals at the customer's company who are advocates for your product.

• Are there any additional team members you consider to be advocates for our product? For example, does anyone stick out as a "power user" or product expert on your team? You may want to interview and include these power users in your case study as well. Consider asking them for tips on using your service or product.
• Is there anyone else on your team you think we should talk to? Again, the more people can share their experience using your product, the better.
• Are there any team members who you think might not be the biggest fans of our product or who might need more training? Providing extra support to those struggling with your product may improve their user experience and turn into an opportunity to not only learn about their obstacles but turn them into a product fan
• Would you share some details about how your team implemented our product? Get as much information as possible about the rollout. Hopefully, they'll gush about how seamless the process was.
• Who from your company was involved in implementing our product? This will give readers more insight into who needs to be involved for a successful rollout of their own.
• Were there any internal risks or additional costs involved with implementing our product? If so, how did you address them? This will give insight into the client's process and rollout and this case study question will likely provide tips on what potential leads should be on the lookout for.
• Is there a training process in place for your team's use of our product? If so, what does it look like? If your company provided support and training to the client, have them describe that experience.
• About how long does it take a new team member to get up to speed with our product? This will help leads determine how much time it will take to onboard an employee to your using your product. If a new user can quickly get started seamlessly, it bodes well for you.
• What was your main concern about rolling this product out to your company? Describing their challenges in detail will provide readers with useful insight.

• How do you measure the value our product provides? Have the interviewee illustrate what metrics they use to gauge the product's success and how. Data is helpful, but you should go beyond the numbers. Maybe your product improved company morale and how teams work together.

Case Study Interview Questions About Product Feedback

Ask the customer if they'd recommend your product to others. A strong recommendation will help potential clients be more open to purchasing your product.

• How do other companies in this industry solve the problems you had before you purchased our product? This will give you insight into how other companies may be functioning without your product and how you can assist them.
• Have you ever talked about our product to any of your clients or peers? What did you say? This can provide you with more leads and a chance to get a referral.

• What is your advice for other teams or companies who are tackling problems similar to those you had before you purchased our product? This is another opportunity for your client to talk up your product or service.
• Do you know someone in X industry who has similar problems to the ones you had prior to using our product? The client can make an introduction so you can interview them about their experience as well.
• I noticed you work with Company Y. Do you know if they are having any pain points with these processes? This will help you learn how your product has impacted your client's customers and gain insight into what can be improved.
• Does your company participate in any partner or referral programs? Having a strong referral program will help you increase leads and improve customer retention.
• Can I send you a referral kit as a thank-you for making a referral and give you the tools to refer someone to us? This is a great strategy to request a referral while rewarding your existing customers.
• Are you interested in working with us to produce additional marketing content? The more opportunities you can showcase happy customers, the better.

Case Study Interview Questions About Willingness to Make Referrals

• How likely are you to recommend our product to a friend or client? Ideally, they would definitely refer your product to someone they know.
• Can you think of any use cases your customers might have for our product? Again, your interviewee is a great source for more leads. Similar industries may have similar issues that need solutions. They may be able to provide a use case you haven't come up with.
• I noticed you work with Company Y; do you know if they are having any pain points with these processes? This will help you learn how your product has impacted your client's customers and gain insight into what can be improved.

Case Study Interview Questions to Prompt Quote-Worthy Feedback

Enhance your case study with quotable soundbites from the customer. By asking these questions, prospects have more insight into other clients and their success with your product — which helps build trust.

• How would you describe your process in one sentence prior to using our product? Ideally, this sentence would quickly and descriptively sum up the most prominent pain point or challenge with the previous process.

• How would you describe our product if you were explaining it to a friend? Your customers can often distill the value of your product to their friends better than you can.
• What do you love about your job? Your company? This gives the reader more background on your customer and their industry.
• What was the worst part of your process before you started using our product? Ideally, they'd reiterate how your product helped solve this challenge.
• What do you love about our product? Another great way to get the customer's opinion about what makes your product worth it.
• Why do you do business with us? Hopefully, your interviewee will share how wonderful your business relationship is.

Case Study Interview Questions About the Customers' Future Goals

Ask the customer about their goals, challenges, and plans for the future. This will provide insight into how a business can grow with your product.

• What are the biggest challenges on the horizon for your industry? Chances are potential leads within the same industry will have similar challenges.
• What are your goals for the next three months? Knowing their short-term goals will enable your company to get some quick wins for the client.
• How would you like to use our product to meet those challenges and goals? This will help potential leads understand that your product can help their business as they scale and grow.
• Is there anything we can do to help you and your team meet your goals? If you haven't covered it already, this will allow your interviewee to express how you can better assist them.
• Do you think you will buy more, less, or about the same amount of our product next year? This can help you gauge how your product is used and why.
• What are the growth plans for your company this year? Your team? This will help you gain insight into how your product can help them achieve future goals.
• How can we help you meet your long-term goals? Getting specifics on the needs of your clients will help you create a unique solution designed for their needs.
• What is the long-term impact of using our product? Get their feedback on how your product has created a lasting impact.

• What will you need from us in the future? This will help you anticipate the customer's business needs.
• Is there anything we can do to improve our product or process for working together in the future? The more feedback you can get about what is and isn't working, the better.

Before you can start putting together your case study, you need to ask your customer's permission.

If you have a customer who's seen success with your product, reach out to them. Use this template to get started:

Thank you & quick request

Case Study Benefits

• Case studies are a form of customer advocacy.
• Case studies provide a joint-promotion opportunity.
• Case studies are easily sharable.
• Case studies build rapport with your customers.
• Case studies are less opinionated than customer reviews.

1. Case studies are a form of customer advocacy.

If you haven't noticed, customers aren't always quick to trust a brand's advertisements and sales strategies.

With every other brand claiming to be the best in the business, it's hard to sort exaggeration from reality.

This is the most important reason why case studies are effective. They are testimonials from your customers of your service. If someone is considering your business, a case study is a much more convincing piece of marketing or sales material than traditional advertising.

2. Case studies provide a joint-promotion opportunity.

Your business isn't the only one that benefits from a case study. Customers participating in case studies benefit, too.

Think about it. Case studies are free advertisements for your customers, not to mention the SEO factor, too. While they're not promoting their products or services, they're still getting the word out about their business. And, the case study highlights how successful their business is — showing interested leads that they're on the up and up.

3. Case studies are easily sharable.

No matter your role on the sales team, case studies are great to have on hand. You can easily share them with leads, prospects, and clients.

Whether you embed them on your website or save them as a PDF, you can simply send a link to share your case study with others. They can share that link with their peers and colleagues, and so on.

Case studies can also be useful during a sales pitch. In sales, timing is everything. If a customer is explaining a problem that was solved and discussed in your case study, you can quickly find the document and share it with them.

4. Case studies build rapport with your customers.

While case studies are very useful, they do require some back and forth with your customers to obtain the exact feedback you're looking for.

Even though time is involved, the good news is this builds rapport with your most loyal customers. You get to know them on a personal level, and they'll become more than just your most valuable clients.

And, the better the rapport you have with them, the more likely they'll be to recommend your business, products, or services to others.

5. Case studies are less opinionated than customer reviews.

Data is the difference between a case study and a review. Customer reviews are typically based on the customer's opinion of your brand. While they might write a glowing review, it's completely subjective and there's rarely empirical evidence supporting their claim.

Case studies, on the other hand, are more data-driven. While they'll still talk about how great your brand is, they support this claim with quantitative data that's relevant to the reader. It's hard to argue with data.

An effective case study must be genuine and credible. Your case study should explain why certain customers are the right fit for your business and how your company can help meet their specific needs. That way, someone in a similar situation can use your case study as a testimonial for why they should choose your business.

Use the case study questions above to create an ideal customer case study questionnaire. By asking your customers the right questions, you can obtain valuable feedback that can be shared with potential leads and convert them into loyal customers.

How to Approach a Case Study - A Structured 4-Step Approach

• Last Updated February, 2023

The Internet is filled with frameworks on how to approach a case study. But which one will help you ace your case and land an offer at a top consulting firm?

At My Consulting Offer, former Bain, BCG, and McKinsey consultants have developed a proven 4-step approach that will help you tackle any type of case study. We’v helped over 600 recruits land the consulting jobs of their dream.

Want to know the secret? Keep reading!

In this article, we’ll walk you through our 4-step approach and talk about what the interviewer expects at each step, including:

• How to approach a case study.
• Clarifying the client’s objectives.
• Framing a logical structure.
• Making sense of the provided information.
• Giving a strong recommendation.

Let’s get started!

Approaching a Case Study

Analyzing the right case information, case interview opening: getting to know the key objective, concluding your case with a strong recommendation, framing a customized problem-solving structure.

A case interview always starts with a prompt. A prompt is the initial information about the case provided by the interviewer. It gives you a brief background of the client’s problem and the key objective.

Here’s an example:

“Your client today is an NYC-based violinist. She’s been saving up for her wedding, but she broke her leg and can’t leave her apartment. She’s got to find a new plan for coming up with her wedding savings now and needs help.”

In the above example, we get to know the background and the objective.

Background: Our client Maria is an NYC-based violinist and has been saving for her wedding.

Objective: Find ways for the client to increase her savings for her wedding without leaving her apartment. 

After the prompt is given, you’re expected to drive the case forward. Our 4-step approach will help you do just that.

• Opening – Understand and reconfirm the objective and ask clarifying questions.
• Structure – Develop a problem-solving structure to answer the key questions.
• Analysis – Dive deeper into analyzing relevant issues and use data provided by your interviewer to make conclusions.
• Recommendation – Give a strong actionable recommendation by tying together the insights.

Let’s dive into each step of the 4-step guide so you can solve cases like a pro!

The first step to solving any problem is to know the key objective a.k.a. the “north star” which will help you guide the case in the right direction.

This seemingly simple, but it’s where many interviewees fail. They think the prompt has given them all the relevant information, so they rush to start solving the problem.

But, as you saw in the prompt, the objective is touched upon but isn’t clear or measurable . You got to know that the client is looking for ways to increase her wedding savings while staying in her apartment with a broken leg.

We still don’t know what the target is and how much of it is already saved. Additionally, as there were no clarifying questions asked, no other details were shared by the interviewer.

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

What should the Case Opening Look Like?

It’s important to ask questions like:

• What does success look like for the client? Does she have a target in mind for her wedding?
• How was she making money before she broke her leg?
• What are her income streams?
• Is she willing to cut her expenses to increase savings or is she looking only for ways to increase her income?

These questions help us understand the following:

Tangible or Measurable Objective – What is the target in the client’s mind?

Additional Information – prior income sources, income source while stuck in her apartment, her focus on increasing income rather than reducing costs.

What does the interviewer expect from you in the case opening?

• Restate the prompt in your own words
• Confirm the key objective 
• Ask a few key clarifying questions (3-5) to know more about the overarching context of the case – making sure you understand the client’s product, business model, or geographic focus 

Now let’s learn how to create a comprehensive and customized problem-solving structure.

The internet is filled with problem-solving approaches and frameworks, like:

• The BCG 2 x 2 Matrix
• The Profitability Formula
• McKinsey’s 7S Framework
• Porter’s 5 Forces

These frameworks help break business problems into smaller parts that can be analyzed to figure out a solution. But as these frameworks are generic, it might feel like they are being force-fitted to the problem in your case. No standard framework will ever fit all situations. 

Creating a case-specific problem-solving structure isn’t difficult and with the right approach, you can create it with ease.

How to Create a Customized Structure

Start with the key objective, increasing Maria’s savings for her wedding. How can we break this problem down into sub-parts? If you were using a generic framework, you might use the 3C + P framework and break the problem into:

• Competitors

You could then think of questions in each bucket that would help Maria understand potential opportunities to expand her income. 

But, with this approach, you wouldn’t be likely to stand out! Lots of candidates will approach this case with the same 4 buckets. This is why a customized approach is important.

While creating your structure, there are a few things that you should do to ensure that your structure touches on all relevant points and helps you to drive the case forward. Your structure should be:

• Logical – Each bucket in the structure should logically align with the key objective.
• Personalized – As you are creating the buckets, personalize them to the case at hand.
• MECE – MECE stands for “ Mutually exclusive, Collectively exhaustive .” This helps you ensure that there are no overlapping buckets and you cover all the key aspects of the problem.
• Depth – As you dig deeper into each bucket, ask yourself if you have covered all possible questions in the bucket. Create sub-buckets of the main buckets wherever necessary.

You can read more about structuring your analysis of business problems in our article on issue trees .

What does a Good vs. Great Structure Look Like?

Comparing the two structures above, we can see that Candidate B has created a better structure than Candidate A. Although Candidate A covered all important aspects, Candidate B has personalized their structure to Maria’s problem.

Communicating the structure in an easy-to-understand manner is as important as creating a robust structure. When communicating the structure:

• Ensure that the interviewer can follow your structure.
• Communicate one level at a time.
• Use a numbered list to walk through the structure.

After walking the interviewer through the structure, you should choose the bucket that should be explored first to answer the key question. You could say something like –

“Now that we have walked through the opportunities for increasing her revenue, I’d like to dive into the skills Maria has that she could leverage.”

The interviewer could either agree or disagree with the first bucket that you want to dig deeper into. Some companies, like McKinsey, use interviewer-led case interviews and will lead you through the case following a specified path. Others, like Bain and BCG, will let you lead the case and just nudge you if you seem to be veering off-path. In either case, you’ll need to start by brainstorming and providing ideas on the first bucket or you’ll need to analyze data and derive conclusions.

There are 3 main types of analysis you may need to do to answer the key question:

Brainstorming

Market sizing, exhibit reading.

Let’s see how each of these would help us drive the case forward and derive conclusions.

In a brainstorming exercise, a strong candidate will generate 8-10 ideas bucketed into categories. In the current case example, you could be asked for ideas on how Maria could make more money.

One set of categories you could use to generate ideas follows what we call the “X-not X” approach. Essentially, you start with a bucket like “playing music” and generate ideas in that bucket. Then switch to “not playing” and generate ideas for this bucket. This will help you in generating at least 2x ideas you otherwise would and will look more impressive to your interviewer because it is MECE and structured.

Let’s see how brainstorming plays out in our case example.

“Maria likes your approach and wants to start right away. Because she is currently not making any money, she would like some ideas. What are some ideas you have on how she could make money? She only wants to focus on leveraging her violin talents.”

The above example shows how you could use the “X-not X” approach to generate a lot of ideas – and how you could even further structure the ideas into “online” and “offline” categories to make it an exceptional brainstorming example.

You may also be expected to calculate the size of a market for your client’s product or service – after all, one of the most important things to know before pursuing an opportunity is the size of that opportunity. In the current example, you could be asked to calculate the income that Maria could earn by offering online violin classes.

There are 2 approaches to market sizing:

• Top-down: This is used when there are no constraints. In this approach, you start with the overall population that may be interested in the product or service and slice it down based on the segments of the market most likely to purchase. The top-down approach is best for national and global markets.
• Bottom-up: This approach is used when there are some constraints, like supply constraints, a limited number of hours, etc. In this approach, you start with the limiting factor and try to estimate the maximum that can be achieved based on the constraints.

Let’s see how we can use market sizing to help our client.

“Maria likes the ideas you came up with. She thought about being a violin teacher at one point since she had a great one when she started as a kid and is curious, how much could she make if she were to teach one-on-one Zoom classes for the next month? She wants to start small before she goes to group classes and, in the beginning, it will be just her teaching.”

Here’s an example of how you could work through this question:

The above shows how you could estimate the income which our client can expect to make in the first month. 

Follow up your analysis by giving your answer the “sniff test.” Does it seem right at a high level? Here we see that $4,000 is the estimated first month’s income, but as this would be the first time Maria will be taking online classes, she won’t be working at full capacity from the start. Her earnings will probably be lower than $4,000.

But, in the long run, it’s a good idea to start offering lessons because at full capacity, Maria will be able to earn $8,000 per month.

In case interviews, you’ll be expected to derive conclusions based on tables or charts provided by your interviewer. In the current example, you could be asked to help the client prioritize which type of client should she target for her violin classes.

Let’s see what data is available and how we can conclude which segment to go after.

“Maria is happy to know that you think providing 1:1 violin lessons over Zoom is a viable idea. 

She knows that a lot of people are interested in violin lessons, but to make sure she can tailor her marketing and lessons, she is interested in only going after one or two segments.

Which one should she go after?”

The first step to deriving insights from an exhibit is to read it thoroughly and ideally interpret it aloud as you go for your interviewer. This chart has data about willingness to pay and competitiveness across various segments. It gives an idea about the level of competition from other violin instructors. The market size of each segment is portrayed using the size of the circle. At first glance, it might seem that the client should go ahead with the segment which has the lowest competition and highest willingness to pay, which is the “Adult-Advanced” segment. But, that segment has a really small market size and Maria would need extensive teaching experience to cater to advanced students.

This is the first time Maria is getting into this market, but she also wants to have a high earning potential. The optimum segment would be one with a good market size and a reasonable trade-off between willingness to pay and competitiveness. 

Based on this, Maria should go with the “college-intermediate” and “adult-intermediate” segments. She would be able to cater to both these segments with ease. Additionally, the combined market size is considerable and the relative trade-off of competitiveness and willingness to pay is suitable as well.

What does the interviewer expect when you are doing analysis and deriving insights?

• Pause to think about the structure for marking sizing or ideas for brainstorming. If you’re asked to read an exhibit, take a moment to understand it and lay out what it says to your interviewer before interpreting the data it provides.
• Offer insights into your client’s problem as the data presents them and draw conclusions.
• Drive the case forward based on the insights. What does this data mean for solving your client’s problem?

Maria came to you with a problem in hand and won’t be thrilled to just get the insights in bits or pieces. Pull your problem-solving together for her with a persuasive recommendation.

Think of the case interview as baking an amazing cake. While the structure and derived insights form the main ingredients for baking the cake, the recommendation is like the cherry on top. It helps in creating a lasting positive impression.

Similar to the opening of the case, the recommendation can seem relatively straightforward, but it is definitely nuanced. MCO’s 5R framework could help you deliver great recommendations for every case.

How should you present your recommendations?

MCO’s 5R Framework:

• Recap: As consultants, you deal with CXO (e.g., CEO, CFO) level clients who are busy with many projects, so recapping the problem you’re solving is essential to set the tone of the meeting.
• Recommendation: State your recommendations clearly without any additional detail to showcase clarity.
• Reasons: Follow this with logical reasons for your recommendations to provide context and show the credibility of the recommendations.
• Risks: Every decision has risks associated with it. Just lay them out so the client knows what to watch out for during implementation.
• Retain: End the recommendations with key next steps to pursue the opportunity, ensuring continuous engagement with the client.

Let’s see how to give a strong recommendation for our case example.

“Your client calls you and wants to know what you recommend.”

What does the interviewer expect when closing the case?

• Keep the recommendation clear and succinct keeping the audience in mind.
• Explain everything with a reason and point out risks associated with the recommendation.
• Be presentable and communicate the recommendations with confidence.
• Ensure that the next steps are clearly laid out.

A final note: Not all cases have a “Right” and “Wrong” answer. In some, the math is very cut and dry but in others, there is a mix of evidence and it is a judgment call on what to recommend. Remember that a well-defended recommendation is more important than the “exact right answer.”

How to answer case study questions.

A case study examination is composed of a set of questions surrounding a single problem, person, place or thing. Each problem attacks different angles of the subject matter to determine if the examinee comprehends the particular problem(s) and can solve them. Case study examinations can be used in business, technology, medicine, psychology, advertising, law, consulting and science. The questions are ideal for testing the knowledge of an individual who must prove his grasp of the subject matter in a particular field, i.e., the legal professional.

A week or two before the case study, locate a practice test and run through it a few times on your own. The more acquainted you are with the word arrangement of this type of test, the more comfortable you will be during either a written or oral case study assessment.

On the day of the case study test, relax and allow yourself to remember what you have learned from previous readings on the subject. You should possess a wealth of knowledge in this area from classes you have taken or work experience. Just use what you already know to answer the questions.

To answer questions on a case study examination in the best possible way, read or listen for the topic sentence. This is usually the first sentence in the introduction or first paragraph. This sentence presents the problem and thus holds key information; it tells you what the problem is about. Make sure that you understand the topic before reading the case study.

Next, read or focus on the meaning of the entire study question to become familiar with the nature and scope of the problem. Go over it again more slowly, a second time, if you do not understand it during the first read. Do not skip, skim or gloss over the content. Otherwise, vital information that you will need to answer the question might be missed. Note word arrangement, facts, figures or statistics in the text that will help come up with a solution. Think of different ways that you can answer the case study question and then determine the effects of each answer on your outcome.

Visualize the scenario or situation posed by the question. See it in your mind's eye as you review it. Consider the question as if it were an actual problem that will affect the lives of others. Write the best possible answer.

Slow down if you start to get confused. You may be moving too fast, trying to beat the clock. If this is the case, answer the easiest questions first and come back to the harder ones later. This will buy you some time and hopefully boost your confidence enough for you to calm down and can answer the more difficult questions with less anxiety.

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?

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 .

You might have other case interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

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.

How to Answer Case Study: few tips

Here are a few tips on how to answer questions relating to case studies;

1)Read the case-study carefully: Case-studies will run up to many lines. So, do not think twice about spending time on reading the question. Read it the second time if [o haven’t understood clearly.

We Will Write a Custom Case Study Specifically For You For Only $13.90/page!

2)Read the questions relating to the case: After a first time reading of the case study, reading the questions pertaining to it, will help you know what to look out for in the case. Underline these instances in the case study for later reference.

3)Make notes of key points: While reading through your case study, make notes of key points (in bullet format).

This will help you to assess and analyses the facts for arriving at the right solution.

4)Look for cues: Sometimes, the answer may be hidden in the question itself. Certain Norms, or conjunctions in the sentence will give away the answer, if you read between them. Remember to look for these cues.

5)Background preparation: attempting case studies questions will be easier if you have enough exposure to solving these question types earlier.

Browse through detent portals or your university online interface to get better insights about case studies, and the mode to solve them.

Case studies are a vital part of testing management expertise and are woven into the distance learning MBA programs, which follow industry-standards. With the above tips, you can practice such type of questions with a new approach and get the expected results. Identification of issues ; problems There are three steps involved in the identification and analysis of issues and problems.

What are The Steps of Writing Content Analysis Case Study ?

Step 1 – overview of the case study (background context)

Understanding the background issues helps to understand the context of the case study. Read the case study to gain an overview and ask and answer the following questions as you read.

* What background facts influence the current problems? * What are the constraints or obstacles of the situation?

Step 2 – identifying the problems Identifying the major problems and their causes at this stage is vital to identify appropriate solutions later. Re-read the case study and summaries or list the issues and / or problems in your own words.

Make sure you: * sort he major problems from the minor problems * identify evidence from the case study which relates to each of the problems * identify underlying causes of the problems. A setup strategy is to represent the problems and their relationships as a mind.

Step 3 – linking theory to problems and case evidence Relating the identified issues / or problems to theory is vital when answering case studies.

This is where you demonstrate your knowledge of the theory in your course and your ability to relate it to practical situations.

If you are afraid to be expelled or think that you will not pass the plagiarism of your work, then it is better to ask for help in writing the case study with us.

Use your readings to select appropriate theories to match the identified problems. * Home * Identifying issues * Solutions * Recommendations I Antispasmodics can be a useful strategy to summaries / organism problems and to show their relationships to each other. The example below is a representation of the problems of the management case study.

Example I * Home * Identifying issues * Solutions * Recommendations I Integrating theory in a case strangulating relevant theory into your case study answer is vital. His allows you to demonstrate how theory relates to the actual issues / problems mound in the case study, as well as demonstrate your understanding of your course content. The following example shows how the theory and issues have been woven together. Example I * Home * Identifying issues * Solutions * Recommendations I Solution’s section evaluates potential solutions for the identified key problems. Often there is more than one solution, so it is useful to evaluate each solution in terms of its advantages and disadvantages.

This will also assist in determining your recommendations.

Things that may need to be considered are: * costs * time * sources * expertise. Structures section should be clear and concise. Recommended structure: * use headings and subheadings where possible * bullet points or numbered lists can also be used to list the advantages and disadvantages. Example I Recommendation’s section should outline your recommendations based upon the given solutions for each of the identified problems.

It may also need to include an action plan, egg what should be done by whom and the associated timeliness, but check with your teacher / lecturer for specific requirements.

Each recommendation would be realistic, ‘e practical and achievable, and be linked back to relevant and supporting theory. Structuralizes and subheadings should be used in this section. For example:communication * Staff constitutionalism the recommendations based on the identified solutions and supported by relevant theory. * Staff meetinghouse the recommendations based on the identified solutions and supported by relevant theory.

Leadership * Team bloodletting the theory. * Participative leadership storyline the recommendations based on the Identified solutions and supported by relevant theory. I

Case Interviewing

What is a case interview.

The case interview is a scenario modeled after a real business or management problem. Candidates are asked to analyze a problem and provide a solution based on the information given. The majority of cases don’t have a specific answer that you are expected to give; instead, the interviewer is looking for you to demonstrate a problem-solving process that is both analytical and creative.

Who Uses This Style of Interviewing?

Many consulting firms use the case interview as part of their interview process. The case gives candidates a sense of the type of work that consultants do and allows the employer to test the candidate’s ability to analyze, present information, and perform under pressure. However, any employer who is looking for strong problem-solving and presentation skills can use case interviewing.

Skills Evaluated During a Case Interview

• Communication skills
• Analytical and reasoning skills
• Ability to organize and present information
• Ability to perform under pressure
• Understanding of basic business principles
• Creativity and resourcefulness

Types of case questions:

• Business case (most common).  A scenario to gauge the general business knowledge of candidates and how they can logically apply this knowledge. It could focus on different areas such as profit/loss, organizational structure, and marketing. Example: “An airline finds that, while its revenues are high, the company is still operating at a loss. What is going on?”
• Market-sizing/”Guesstimates.” Estimation questions that require the use of logical deduction and general statistical information to estimate some number or size. Example: “How many gas stations are there in the U.S.?” 
• Brainteasers.  Puzzles or logic questions used to gauge creativity, quantitative skills, and problem-solving skills. Example: “Why are manhole covers round?” 

How to Approach a Case Interview

• Listen to the case . Take notes and rephrase the question to make sure you’ve got all the information.
• Clarify the problem . Ask good questions to clarify and show your understanding of the problem.
• Analyze the problem . Pause and take time to think about how you will approach the problem. Silence is okay!
• Structure an answer . Write out your method for solving the problem. Use examples from in and outside the classroom to show insight.
• Share your answer . Talk through your approach using key points to guide you.
• Summarize your findings . Provide a conclusion that restates your main points.

How to prepare for a case interview

The best preparation for a case interview is to PRACTICE. The more cases you work through, the more comfortable you will become with the process.

Use this general timeline and the resources below to structure your practice:

As early as possible

• Read the case resources Case in Point and the Vault Guide to the Case Interview .
• Coordinate an informational interview with a Georgetown alum working in consulting. Use Hoya Gateway to get connected.
• Sign up for a mock interview to practice your behavioral interview skills (these are important too!).

Case Interview Tips

• Take notes.
• Remember, the case is a chance to demonstrate how you think – don’t be discouraged if you don’t know the industry well. Use your analytical and communication skills to show how you would break down the problem.
• Make sure you understand the problem you are being asked to analyze. Paraphrase back to the interviewer to make sure you heard them correctly.
• Ask questions and listen to the answers you get (don’t be discouraged by information that the interviewer doesn’t provide, that likely means it is not important).
• Take time to collect your thoughts (and ask for more time if you need it). Don’t be afraid of silence.
• Lay out a road map for your interviewer (your framework will help here).
• Think out loud to allow the interviewer to see your analytical skills.
• Present your thinking in a clear, logical manner.
• Summarize your recommendations and use examples from your classes, internships, or extra-curricular activities to provide insight beyond the case.
• Read industry magazines and journals (both general and specific).
• Familiarize yourself with some basic statistics, such as the population of the U.S.

There are several resources available both in the career center and online, which can help you prepare for case interviews.

60 Case Study Questions for Customer and Client Interviews

Prospective customers respond to proof. You make a stronger case when you can show concrete results. This is where a case study comes in. A case study strengthens your sales pitch by telling a firsthand story of how you successfully provided solutions to your customer’s problems. The benefits of case studies are tangible, as they can serve as the final push from consideration to sale. Case studies should be a core component of your marketing strategy. 

Boost your case studies by interviewing previous customers and asking them to share how they benefited from your business. Interview your loyal customers using the following questions to build convincing case studies you can share with new prospective clients.

What Are the Key Elements of a Good Case Study Questionnaire? 

A good case study clearly outlines common problems and walks the reader through the steps you took to solve it. It should focus on the solutions and tell the client's story in a relatable way by exploring your customer’s experience. Specific outcomes can strengthen your sales pitch, so interview past customers who have experienced measurable results. 

An effective interview requires thoughtful, specific questions to avoid getting multiple versions of the same answer, which won't give you what you need to build your case study. Vary your question types to cover a wide range of topics and get more valuable feedback. Ask questions that will likely result in quotes you can use within your case study.

It's also important to remember that, even if you start off with a list of questions, your interview may end up turning into a conversation. Although it's useful to prepare questions ahead of time, don’t get too stuck on your questionnaire. Let the conversation flow where it will and ask follow-up questions when warranted. 

By having a conversation, you can focus on commonalities with your clients and make them feel more comfortable giving the interview. To get a feel for the process, try conducting a mock interview with one of your colleagues and ask them to give you feedback on your interview style. 

How to Write Great Case Study Interview Questions

Case studies are an excellent resource for highlighting happy customers, but some people have trouble articulating their stories. Perfecting your case study questions and brushing up on your interview skills gives you the foundation for a compelling case study.

First, identify why you're writing your case study to outline the major problems you intend to highlight. Then draft your questions. 

Seasoned B2B marketing leader, Jehan Lalkaka , offers the following insight: “A great case study question starts with being genuinely curious about your interviewee’s challenges and how they overcame them. Pre-planned questions are nice to have, but they just open the door. Rich client stories come from asking follow-up questions, by listening to a client’s initial response and knowing when to dig deeper. Look for nuggets of insight that your client can bring to life, and at the same time, will resonate with future clients who may be on the same journey."

You don't need to follow up on every answer, but if your client says something unexpected or something you think will impact your target audience, probe further. Your interview outline should serve as a guide to start the conversation. 

Start With a Backstory of Your Customer’s Business

When interviewing your clients, you'll want to introduce them to your audience by sharing some background information on their company. Then, set up the case study by presenting the initial problem.

• Tell me a little bit about your business and its history.
• Who are your target customers?
• What value proposition does your business offer your customers?
• Describe your role at the company.
• What are some common challenges faced by businesses in your industry?
• What problems or challenges were you facing that led you to seek out our product/service?
• Why was this specific challenge a priority?
• How was this problem impacting your business?
• What other potential solutions had you tried before?
• Why weren’t other potential solutions working?

Include Questions About Your Customer’s Decision Process

Since case studies are essentially marketing tools that help you close sales with people in the decision stage, you want potential customers to understand what makes you stand out from the competition. Exploring a happy customer’s decision-making process can give you insight into your unique selling proposition without being overt about why you’re the best. 

• What challenges were you experiencing when you decided to evaluate our product/service? 
• What were you looking for in your ideal solution? 
• What trends were you seeing that made you contact us? 
• Why didn’t you seek out a solution sooner? 
• Which factors weighed most heavily in your decision? 
• What risks did you consider? 
• What goals did you intend to meet with our product or service? 
• Describe your decision-making process. 
• How do you vet potential vendors? 
• How would you change the buying process? 

Establish Your Relationship

After setting up the problem and why it was significant to your customer, ask them to define their relationship with your brand.

If you are interviewing repeat customers, ask them how they discovered your business, why you were their chosen solution, and what's kept them coming back. If you are interviewing a first-time client, ask what drew them to your business over another.

• Which teams or departments were involved in selecting our product?
• How were you included in the decision-making process? 
• How long have you been a customer with us?
• How did you first hear about our business?
• What made you choose our company over competitors?
• What was your first impression of our business? 
• How was your experience during the onboarding process? 
• How did you envision using our product or service to drive your solution?
• How does our company’s mission align with your company’s mission?

Have Them Demonstrate Your Product and Provide Feedback

Now it's time to dive into the details of the actual case study. Ask specific questions about how your client used your product or service.

Be detailed. These answers will help you draft a case study that resonates with prospective buyers who are facing the same issue. Don't be afraid to ask clarifying questions here or ask for examples.

• How did you use our product or service to create your solution?
• Which features of the product did you find most beneficial?
• What unexpected benefits or challenges occurred during implementation? 
• Was this product a replacement for a similar tool you had used in the past?
• If so, how did it compare to your previous tool? 
• How many people at your company use our product?
• How did you navigate change with your staff? 
• What are the advantages of using our product over another similar one?
• How was the setup and implementation process?
• What was your main concern about rolling out our product or service? 
• Did you contact the customer service team any time during the process?
• If so, how was your customer service experience?
• How was the rollout process?
• What types of feedback have you received from employees about our product?
• Are any of your team members using our product in unexpected ways? 
• How has our product changed daily life for your team? 

Outline the Product’s Benefits and Contributions to Success

This section of your interview will delve into the actual solution and its results. Use this section to ask about specific outcomes and metrics the company used to track successes.

• How did our product address your specific challenges?
• What kinds of measurable results did you see?
• How were your customers impacted by the change?
• What kinds of feedback have you gotten from customers since implementing our product?
• Which key performance indicators (KPIs) or metrics did you measure to determine whether our product successfully solved your problem?
• How has your business changed since you deployed our product or service?
• How is your initial problem currently impacting your business? Is it still an issue, or has it been resolved?
• How would you recommend other customers use our product to get the best results?

Wrap Up the Interview and Include Referral Questions

At the end of your marketing case study interview, ask some general questions about customer satisfaction and relationship management. You can use these to conclude the case study. This section of the interview is also likely to generate some potential customer quotes you can use in your marketing materials.

• Have you referred us to your friends or clients?
• How likely are you to work with us again?
• How can we improve our product to best meet your future needs?
• What are the top five reasons you would recommend us? 
• In which other instances can you see our product providing a viable solution?
• Is there anyone else I can talk to for more information?
• How do you see our business relationship going forward? 

How to Ask Your Clients for Case Study Interviews

If you have been in business for a while, you probably know your best advocates. Think about your top customers, and start by asking those who are the most likely to promote your business.

If you know a client who often refers customers to you, ask them for a specific example of how your company helped them solve a problem. When in doubt, talk to your sales team or your project managers to see if they know of any potential customers who would be happy to share their success stories.

Consider your customers’ time. Don’t approach them for an interview in the middle of a busy season or if they have had a recent issue with your company. Get familiar with your selected clients and how they intend to use your product before implementing it so you have some background information before starting the interview.

Finally, write a personalized request. Don’t send out a form email requesting case studies. Make your requests relevant to each potential interviewee so they know they are valued customers.

Sample Case Study Questions and Answers

These sample case study questions and answers demonstrate how to extract information from your interview and turn it into an engaging business case study that is interesting and informative.

This case study from Switch, a digital marketing agency, details how the company was able to help a client improve its return on investment (ROI) on search and Facebook ad campaigns by moving them from their in-house marketing team.

The digital marketing case study starts with an impressive statistic — the company improved its ROI on search ads from 1.2x to 19x in a short time. The case study breaks this statistic down for potential leads who might not be familiar with marketing terminology, indicating that its client was able to increase sales without spending more on search engine ads.

To appeal to readers with a short attention span, Switch added a short summary of the case study up front under the header TL;DR which is text speak for “too long, didn’t read.” If your potential customers are pressed for time, consider adding a short summary up front. 

While the actual case study interview is not published, a sample question and answer that would have generated this data could be:

Q: How did shifting the development of search engine ad campaigns to Switch impact ad performance?

A: The Switch team was able to change our approach. Before, we used a single strategy on our search and Facebook ads. Their team was able to create split campaigns targeted to different audiences and run A/B tests to refine the messages. In a couple of months, our ROI on search ads went from 1.2x to 19x.”

This case study goes into detail about how Switch worked with its clients to refine the Facebook and search ad strategy, ending with impressive results.

Compose.ly’s MailChimp Case Study

In the digital landscape, every company is fighting to stand atop the search engine rankings. This was Mailchimp’s goal when they sought out Compose.ly to help with their content strategy.

Even well-known brands need quality content to grow their web presence and move ahead of the competition. MailChimp commissioned 41 articles over eight months targeting relevant keywords and phrases while telling a compelling story. Compose.ly writers contributed about five long-form articles per month, and within four months, MailChimp saw a major improvement in their search engine rankings.

Compose.ly 's MailChimp case study outlines the impact that strategic content marketing and effective SEO has had on MailChimp's business.

This study focused on outcomes generated by specific articles and search terms. It highlights the value of being specific with your line of questioning. MailChimp's case study showcases a brand with strong recognition that wasn't getting traction in search results. The client chose to highlight how Compose.ly helped boost results for established services and new services that were in their early stages. 

This case study also offered detailed insight into the process. Instead of just stating that Compose.ly used technical writers to work on SEO-optimized content, the case study breaks down how MailChimp decided where to focus. 

When interviewing clients for your case study, ask your clients to go in-depth. Potential customers will be interested in the process. They may also want to know what to expect from you before committing to your product or service. By exploring your past client's process in detail, you can answer prospect questions. You can also use these process-oriented case studies to address objections a prospect may have. 

The conclusion of the MailChimp case study showcases specific outcomes, particularly that they started seeing results before the project was complete. Highlighting successes can make your prospects excited about what you can potentially do for them. When you're structuring your customer interview questions, ask for timelines and other numbers that show how you got results. 

Best Practices for Conducting A Business Case Study Interview

When you’ve found client advocates who are willing to talk to you about how your company led them to success, draft your interview questions. Keep these best practices in mind.

Be Prepared

Being well-prepared for your interview is the best way to ensure its success. Before meeting with your client, learn what you can about the client so you can flesh out the case study. Conduct a mock interview to prepare. Talk to your sales team or the client’s specific project manager for details to better understand the client and what they were facing when they hired your company or purchased a product.

Ask Open-Ended Questions

Structure your questions so the interviewee has to give detailed answers. If you limit your interview to "yes" or "no" questions, it can be hard to gather enough information to write your case study. Open-ended questions let your client get into the specifics surrounding the study.

Do a Deep Dive

One reason you should record your interviews and transcribe them later is so you can focus on the client’s answers. Often, information will come up in an answer to one question that will prompt you to ask a follow-up question. Recording your interview lets you deviate from your prepared questions to get a more robust analysis of the case.

Create Effective Case Studies With Compose.ly

Case studies are an effective tool marketing teams can use to convince buyers in the consideration stage and the decision-making stage. But they require a skilled touch to successfully articulate the client’s problems and your solutions in a convincing way. 

Compose.ly's case study writing service will take care of the interview, the writing, and the approval process. Work with our team of expert writers to turn past client successes into future sales.

Hawaii Teachers Say They Want To Prioritize Civic Education — But They Need More Help

Despite major changes to education standards six years ago, not all students are getting the same level of support in developing the skills they need to become active citizens.

At Kalanianaole Elementary and Intermediate School, Denise Mazurik and her students were frustrated that the local beach park had been closed for years. Generations of families had enjoyed access to the Big Island park, Mazurik said, and she wanted the same opportunity for her students in 2020. 

When Mazurik saw that Hawaii County Council had scheduled a meeting about closed beach parks, she tasked her seventh-grade students with submitting written testimony. No immediate change came from the meeting, but Mazurik said it was important for her students to connect with their local government. 

“I think the kids felt empowered by writing their testimony, so it’s a win,” Mazurik said. 

Hawaii teachers have faced increased pressure in recent years to improve civic education amid concerns over the state’s dismal voter turnout rate and changes to state education standards aimed at increasing the type of hands-on learning Mazurik incorporated in her classes.

But teachers say it’s difficult to help students learn about and engage in their communities with limited training and few lesson plans related to Hawaii’s history and government.

Hawaii is one of 43 states that require a class in civics, according to the educational nonprofit CivXNow . Students in the DOE must take four years of high school social studies, including a semester-long class on government and the Constitution. 

Since DOE revised its social studies standards in 2018, teachers in Hawaii have also been tasked with nurturing a new generation of active citizens by getting students to take lessons from the classroom and apply them to real-life situations.

“Action can be small but meaningful,” said DOE social studies specialist Rosanna Fukuda, adding that civic engagement can range from writing to legislators to having student discussions on appropriate classroom behaviors. 

While some teachers have embraced the revised standards and tasked their students with testifying at the Legislature or participating in community meetings, others say they’ve made few changes in their classrooms in the last six years.

“I think we’re a long way from where we need to be,” said Rep. Amy Perruso, who previously taught social studies at Mililani High School. Perruso also serves as vice chair of the Commission to Promote and Advance Civic Education, which was formed in 2021 through the state Supreme Court.

A Need For More Training

High-quality civic education should allow students to engage with the lessons they learn in the classroom, said Colin Moore, an associate professor of political science at the University of Hawaii Manoa.

Students need to know about the three branches of government and the Constitution, he added, but it’s equally important for them to learn how to vote or advocate for an issue. 

“Both of those are essential. You can’t be effective as a civic actor if you have no idea what’s going on,” said Moore, who helped develop the social studies standards DOE adopted in 2018. 

Under DOE’s revised standards, every social studies class should incorporate civic education, said Amber Makaiau, an associate specialist at UH Manoa’s College of Education. These classes range from Pacific Island Studies to World History and Culture across grades kindergarten through 12.

The standards require students to develop the skills of active citizens, like collaboration and critical thinking, which teachers can develop through hands-on projects or class discussions, she added. 

“These are everyday human skills that we need if we’re going to have a democracy,” Makaiau said. 

But, Moore said, DOE needs to help teachers put the standards into practice. Not all teachers feel confident teaching civics, he added, and schools typically undervalue social studies because it doesn’t show up on standardized tests in the same way as math or reading. 

In DOE, Fukuda is the only curriculum specialist overseeing resources and professional development for social studies teachers. She’s supported by two resource teachers, but neither of the positions are permanent, Fukuda said. 

Fukuda estimated that she’s held up to 200 training sessions on the new standards since 2018. But it’s difficult to reach nearly 260 schools across the state, and she sometimes relies on complex area administrators to relay their standards training to local teachers. 

“It’s almost never enough,” Fukuda said. 

Eighth-grade teacher Aaron Kubo said the social studies department at Hilo Intermediate School has discussed the new standards since 2018, but he doesn’t remember attending a formal DOE training. 

“I can’t honestly say there was a huge push by our Hawaii DOE to push social studies education to the forefront,” Kubo said. He added that additional training may not have been necessary at his school, since teachers have always encouraged students to develop the critical thinking skills valued under the new standards. 

At Aliamanu Middle School in Salt Lake, Ehren Meinecke thinks the new standards have encouraged some teachers to include more civics into their lessons. 

For example, leading up to the November elections, Meinecke said he’ll discuss political parties and the history of voting rights with his students. Students will then participate in Kids Voting Hawaii, which simulates the state’s general election and allows students to cast votes online. 

“I think it does give them more of a boost of why they want to learn this,” Meinecke said. 

Curriculum Shortages Remain

Every other year, UH law professor Troy Andrade holds teacher workshops on the Supreme Court case Korematsu v. United States, which upheld the incarceration of Japanese Americans during World War II. In his presentation to middle and high school educators, Andrade offers suggestions on how they can teach about the case, Japanese American incarceration camps and their connection to Hawaii. 

While lesson plans on the federal government and U.S. history are readily available online, Andrade said, there’s a lack of materials that specifically tie civics to Hawaii. 

“Those resources, right now, are just not there,” Andrade said. 

It can take several hours to develop a single social studies lesson plan, Mazurik said. She wants to find a curriculum that discusses Hawaii’s history and local government, but she often has to develop the lessons herself, she added. 

“We don’t have the time to create materials that are what our students deserve,” Mazurik said. 

Earlier this year, a DOE task force evaluating civic education in Hawaii found that social studies educators needed more resources and lessons that could be used in grades kindergarten through 12. 

Hawaii’s American Judicature Society hopes to address the gap in curriculum by developing an online bank of lesson plans focused on civic education that are aligned with DOE standards. The materials will focus on Hawaii’s government and history, said AJS Director Sylvia Yuen. She hopes some plans will be available by the end of this year. 

The state grant funding the project expires in December, Yuen added, but AJS hopes to receive more support to cover the costs of developing additional lesson plans in future years.

Makaiau said she always welcomes more classroom resources. Students need exposure to civic education throughout their school careers, Makaiau said, and teachers play a crucial role in keeping democracy alive. 

“It’s not a one-and-done,” Makaiau said. “It’s something that we all constantly have to remain vigilant about.”

Human Resource Management International Digest

ISSN : 0967-0734

Article publication date: 5 July 2024

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Design/methodology/approach

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

This paper aimed to explore the relationship between organizational developmental HR practices and employees' commitment to their organizational career (COC), while examining the impacting role of psychological availability and the additional impacts of organizational links and employee fit. The study found that psychological availability drives the positive effect of developmental HR practices on COC, and this effect is stronger for employees with closer organizational links and better fit within the organization. The two most pertinent managerial insights are to: (1) invest in comprehensive developmental HR practices to nurture employee growth and commitment, and (2) to foster a work environment that promotes psychological availability and cultivates strong links and fit within the organization.

Originality/value

The briefing saves busy executives, strategists and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

What are you looking for?

Some topics you might be interested in, understanding e-bike standard ul 2849: commonly asked questions.

Global markets for electric bicycles (e-bikes) are growing, but so are concerns over safety. We answer some commonly asked questions about UL 2849, the safety standard for electrical systems in e-bikes.

In November 2021, the US Occupational Safety and Health Administration (OSHA) adopted two e-bike-related standards for the workplace under the National Recognized Testing Laboratory (NRTL) program. These were:

• UL 2272 – Standard for electrical systems for personal e-mobility devices
• UL 2849 – Standard for electrical systems for e-bikes

Since then, the use of these standards has received wider recognition. In December 2022, the US Consumer Product safety Commission (CPSC) issued a letter to more than 2,000 businesses stating that failure to conform to relevant voluntary standards may pose an unreasonable risk to consumers. The letter specifically references UL 2272 and UL 2849, stating compliance with these standards, “significantly reduces the risk of injuries and deaths from micromobility device fires.” 1 Manufacturers and importers were warned that failure to conform to these standards could result in enforcement action. 

While this acted as a strong indication that UL 2272 and UL 2849 must be adopted by businesses manufacturing or importing e-bikes for non-work-related uses, the standards themselves remain voluntary. However, in September 2023, things changed when a new law came into effect in New York City (NYC) – Int 0663-2022. This made it illegal for anyone to distribute, sell, lease, rent or offer for sale, lease or rent a powered bicycle that did not conform to the following requirements:

• Electrical system must be certified as compliant to UL 2849 by an accredited testing laboratory (or similar safety standard established in consultation with the fire department)
• Accredited testing laboratory’s certification logo, wordmark or name must be displayed on either:
• Packaging or documentation provided at time of sale
• Directly onto the e-bike or e-bike battery

UL 2849 was recently revised and is now recognized by the Approved American National Standard (ANSI) and National Standard of Canada, making it applicable to both markets.

Commonly asked questions about UL 2849

1. Will battery certification to EN 15194 be accepted?

UL 2849 states the options for battery evaluation are as follows:

• UL 2580/ULC-S2580
• UL/ULC 2271
• CSA C22.2 No. 62133/UL 62133

Additional testing is required for options c and d.

It should be noted that the requirements for certain city/state jurisdictions may be different. For example, New York City (NYC) mandates that batteries must meet UL 2271 without alternatives, but California will accept UL 2849 or EN 15194.

2. Have you seen an increase in brands and suppliers reaching out to SGS following the CPSC’s letter recommending adherence to UL 2849?

We have found many businesses are reaching out to us, trying to understand what the rules are and who the authority is. As most manufacturers and suppliers are aware, the CPSC requires the mechanical parts of a bike to conform to CFR 1512, but this does not address the electrical systems of an e-bike. The CPSC is currently looking into regulations for the electrical systems of bikes, which is where UL 2849 comes into play. This would make sense, as OSHA has already adopted UL 2849 and several cities and states are considering similar regulations.

3. I have heard UL tends to only accept test results from UL test laboratories. Is that true?

I cannot speak for what our competitors may accept, but I can say that SGS will accept any component certified by one of OSHA’s 21 accredited NRTLs. So long as a component is certified by an NRTL to the applicable standards in UL 2849, that is good enough for SGS.

4. What is the difference between compliance to UL 2849 and certification?

Certification must be provided by an ISO/IEC 17065 accredited laboratory or NRTL. To show compliance to UL 2849, testing must be performed by a facility with ISO/IEC 17025 accreditation.

5. Can you test e-bikes and e-mountain bikes (e-MTB) for CE marking in the US?

SGS can test e-bikes to EN 15194 and e-MTB to EN 17404 in the US, China and Taiwan.

6. Does SGS offer risk assessments or another service to review bikes and test reports? Even though our product meets all UL standards, we would like support in identifying shortfalls in bike designs and warnings.

SGS can perform a risk assessment as per the requirements in ISO 12100, as referenced in UL 2849. We can also conduct a protocol review for applicable requirements outside of electrical.

7. How long does it take to test an e-bike to UL 2849, and what are the associated costs?

This question often comes up, and the answer varies depending on several factors. Component-level approvals are a significant factor affecting both time and costs, and so is preparation. The first step involves a document review and meetings with clients and their suppliers (if requested) to ensure the components of the e-bike are certified and approved. If this proves to be the case, timing is much quicker.

Also, SGS can perform certification on the e-bike battery pack to UL 2271, but if you already have an approved battery pack, this will significantly reduce testing costs.

8. Does adherence to UL 2849 automatically mean the battery meets UL 2271?

9. Where does SGS perform e-bike tests?

We have e-bike capabilities in Atlanta (Georgia, USA), Taiwan and Shenzhen (China).

10. Around satisfying the NYC law, is complete bicycle UL 2849 testing required for e-bikes that use system parts that are individually UL compliant?

NYC requires certification of the finished e-bike to UL 2849, and the CPSC says e-bikes should be tested to UL 2849. Having approved components does not necessarily mean the finished e-bike will also meet the requirements in UL 2849. In addition, the electrical system itself needs certification to UL 2849.

11. As part of the testing and certification process, does SGS inspect system component manufacturer plants or are additional plant inspections required?

We only inspect manufacturing plants associated with the listing certification under UL 2849. Certified components that are used to construct the e-bike will have their own factory audits from their NRTL vendors. If we also certify the component, we would, of course, also be auditing those factories.

12. We deal with multiple e-bike models and so often, while the battery and motor will be the same, other components may differ. Can you test one e-bike using the battery, but different components to certify all models or would you need to test each specific bike with its individual components? Components would include the operator display, and similar, that could have alternate choices that are still certified to the appropriate standard, in most cases 62368. For us, the battery pack and motor controller are essentially integrated and certified to UL 2271.

It is okay to have alternate battery packs certified to UL 2271. For the motor controller, we would need to look at that because we do have to do the ISO 12100 risk assessment and functional safety testing to UL 13849. It therefore depends on the component, but we can usually list alternate components in our certification if requested, as we know supply chains are changeable.

13. We are talking about UL 2849, but where does EN 15194 fit in and is it acceptable in the US?

EN 15194 is the CE standard used for e-bikes in Europe. EN standards are generally not accepted in the US, although it should be remembered California does currently allow compliance to EN 15194.

14. We have heard that UL is receiving pushback from e-bike manufacturers, saying UL 2849 requirements are too strict. Is there any truth to this and do you foresee the UL 2849 requirements getting any easier?

I think some of the struggles might relate to the sourcing of components that meet the certification requirements. Also, traditional bike manufacturers are not used to having to source certified components for their bikes, but this is common practice for any other type of electrical product.

15. NYC is refining its language and I know San Francisco is considering passing similar requirements. Are there any other states or cities that require testing or are considering it?

California passed a bill in October 2023 calling for compliance to UL 2849 or EN 15194. Toronto, Canada, passed a ruling for battery compliance to UL or CE requirements, effective April 09, 2024. 

16. We have been struggling to get a complete list or a way to determine which brands have what certifications. Are there any labeling or documentation requirements for e-bikes following certification?

Brands providing certified complete systems or components should have those products marked with the certification company’s logo. You may also reference the certification company’s online certification directory to access information regarding the certification standard and alternate components that are certified by that company.

17. What are the chances of getting positive testing results to UL 2849 without close cooperation with the suppliers of the electrical systems?

It may be difficult to test components on your own against the component standard called out in UL 2849 without details of the component construction. Even if this information is provided for testing, moving forward may be risky as the e-bike manufacturer does not have control over the supply chain for that component. Therefore, even if the design alters slightly, they may find a compliance problem for the end product.
