McKinsey Interview Process

The timeline and dates in the McKinsey interview process may slightly differ depending on whether you are applying as an undergraduate student, MBA student, advanced degree student, or working professional.

However, the overall components in the process are roughly the same. The McKinsey interview process has five major steps:

1. Attend McKinsey networking events

McKinsey typically hosts several networking events before the McKinsey application is due.

Attending these events is not required. If you have a strong resume and background, you can still receive a McKinsey interview even if you did not attend any events.

If you attend a top-tier undergraduate or MBA school, these networking events are less important. McKinsey has relationships with these schools and consistently hires students from these schools every year for consulting internship and full-time opportunities. Your resume will get reviewed regardless of whether you attend a networking event or not.

If you do not attend a top-tier undergraduate or MBA school, these networking events will be much more important. Since your school is not a school that McKinsey targets, McKinsey recruiters spend much less time looking at applications from your school. Networking is crucial to giving your resume an opportunity to be reviewed.

Similarly, if you are applying to McKinsey as a working professional, networking events are much more important. Although McKinsey hires people from nontraditional backgrounds, you will need to do the work needed to get your name and resume in front of recruiters through networking or referrals.

2. Submit your McKinsey application

After all of the networking events are over, McKinsey will have a deadline for submitting your application, which typically consists of four components: McKinsey application questions, resume, cover letter, and referrals.

3. Pass your first round McKinsey interview

A few weeks after the application deadline, you will receive an invitation from McKinsey for the first of two rounds of interviews.

If you are applying as a student, interviews will take place on your school’s campus. If you are applying as a working professional, interviews will take place at the McKinsey office that you are applying for.

Your McKinsey first round interview consists of two separate 40- to 60-minute interviews. The majority of the time will be focused on case interviews, but you will also get a few other types of questions.

4. Pass your second or final round McKinsey interview

Your  McKinsey final round interview will typically consist of two to three separate 40- to 60-minute interviews. You’ll see the same four types of McKinsey interview questions that you saw in your first round interviews.

• McKinsey case interview
• McKinsey Personal Experience Interview (PEI)
• “Why McKinsey?” question
• “Why Consulting?” question

There are three important distinctions between your first round McKinsey interview and your final round McKinsey interview.

One, your interviewers will likely be more senior people at McKinsey. This means that the case interviews you receive may be a bit less structured and more qualitative in nature. The case interview may feel more like a discussion where you and the interviewer are discussing your opinions and ideas on a business problem.

Two, there will be more of an emphasis on assessing your fit with the firm. The first round interview is primarily used as a screener to determine whether or not you can solve case interviews effectively and whether or not you have the potential to be a great consultant.

Final round interviews will also continue to assess this, but interviewers will also be determining whether or not you would be a great fit with the office. Are you coachable and easy to work with? Are you collaborative? These are a few of the qualities that interviewers want to see.

Three, your interviewers may read the notes that your interviewers wrote during your McKinsey first round interview. If there was a particular area of the case interview that you struggled with, interviewers may want to test you again on it to make sure that it is not a significant weakness.

5. Receive your McKinsey Offer

After finishing your final round interview, all you have left to do is to wait for your McKinsey offer. McKinsey typically calls candidates to tell them that they are being extended a job offer before emailing them.

Some candidates receive a phone call with good news on the same day of their final round interview. Most candidates receive their call within a few days.

If you have not heard back from McKinsey after a few days, that does not necessarily mean that you did not receive a McKinsey offer. Sometimes, you may be on the borderline of receiving an offer and McKinsey would like to finish interviewing other people before deciding whether or not to give you an offer.

Be patient on waiting for McKinsey to get back to you. If you have not heard back in a week, you can send a follow-up email with the recruiter to ask if there are any updates.

When you finally get your call and offer letter, all that is left to do is sign to secure your job at McKinsey!

What is a McKinsey Case Interview?

A McKinsey case interview , also known as a “case” for short, is a 30 to 45-minute exercise in which you and the interviewer work together to develop a recommendation or answer to a business problem.

These business problems can be anything that real companies face:

• How can Uber increase its profitability?
• What can Netflix do to increase customer retention?
• How should Tesla price its new electric vehicle?
• Where should Disney open another Disneyland theme park?

McKinsey case interviews simulate what the consulting job will be like by placing you in a hypothetical business situation. Cases simulate real business problems that consulting firms solve for their clients. Many McKinsey case interviews are based on actual projects that interviewers have worked on.

While McKinsey consulting projects typically last between 3 to 9 months, McKinsey case interviews condense solving the business problem into just 30 to 45 minutes.

McKinsey case interviews can cover any industry, including retail, consumer packaged goods, financial services, energy, education, healthcare, government, and technology.

They can also cover a wide range of business situations, including entering a new market, launching a new product, acquiring a company, improving profitability, and growing revenues.

Although McKinsey case interviews cover a wide range of industries and business situations, no technical or specialized knowledge is needed.

Why Does McKinsey Use Case Interviews?

McKinsey uses case interviews because they are the best way for McKinsey to predict which candidates will make the best consultants. McKinsey case interviews do not predict this perfectly, but they come quite close. Assessing candidates based only on their McKinsey resume is not sufficient. 

Since McKinsey case interviews simulate the consulting job by placing you in a hypothetical business situation, McKinsey interviewers use case interviews to see how you would perform as a hypothetical consultant.

Many of the skills and qualities needed to successfully complete a case interview are the same skills and qualities needed to successfully finish a McKinsey consulting case project.

Case interviews also give you a sense of whether you would like the consulting job at McKinsey.

If you find case interviews interesting and exciting, you’ll likely enjoy consulting and working at McKinsey. If you find case interviews dull and boring, consulting may not be the best profession for you.

What Do McKinsey Case Interviews Assess?

McKinsey case interviews assess five different qualities or characteristics.

All of these five qualities can be assessed in just a 30 to 45-minute McKinsey case interview. This is what makes case interviews so effective in assessing consulting candidates.

1. Logical, structured thinking

Consultants need to be organized and methodical in order to work efficiently.

• Can you structure complex problems in a clear, simple way?
• Can you take tremendous amounts of information and data and identify the most important points?
• Can you use logic and reason to make appropriate conclusions?

2. Analytical problem solving

Consultants work with a tremendous amount of data and information in order to develop recommendations to complex problems.

• Can you read and interpret data well?
• Can you perform math computations smoothly and accurately?
• Can you conduct the right analyses to draw the right conclusions?

3. Business acumen

A strong business instinct helps consultants make the right decisions and develop the right recommendations.

• Do you have a basic understanding of fundamental business concepts?
• Do your conclusions and recommendations make sense from a business perspective?

4. Communication skills

Consultants need strong communication skills to collaborate with teammates and clients effectively.

• Can you communicate in a clear, concise way?
• Are you articulate in what you are saying?

5. Personality and cultural fit

Consultants spend a lot of time working closely in small teams. Having a personality and attitude that fits with the team makes the whole team work better together.

• Are you coachable and easy to work with?
• Are you pleasant to be around?

What is the Format of a McKinsey Case Interview?

Although there is a wide range of different cases you could be asked to solve, all McKinsey case interviews follow the same progression.

• Understanding the case background : the interviewer will provide you information on who the company or client is, what their business problem is, and any other relevant context needed for the case
• Asking clarifying questions : you’ll have the opportunity to ask questions to confirm your understanding of the case
• Structuring a framework : you’ll create and present a framework to the interviewer that organizes your thoughts and identifies the different areas or key questions you’d like to further investigate
• Starting the case : the interviewer will ask either a quantitative or qualitative question for you to answer
• Solving quantitative problems : the interviewer may ask you to perform math calculations, such as calculating profit, breakeven , or analyzing charts and graphs 
• Answering qualitative questions : the interviewer may ask business judgment questions to assess your business acumen and intuition
• Delivering a recommendation : the interviewer will ask you for your final overall recommendation for the case.

It is worth noting that while most consulting firms opt for a candidate-led interview approach, where the interviewee takes the lead in navigating a case, McKinsey stands out with its interviewer-led format .

In McKinsey's interviewer-led approach, the interviewer plays a more active role in guiding the conversation. 

Rather than the candidate taking charge of the case, the interviewer presents the business problem and directs the discussion. 

This approach aligns with McKinsey's emphasis on teamwork, collaboration, and adaptability, skills crucial in the world of consulting. By simulating the client-consultant interaction, this approach helps assess how candidates handle challenges in real-time discussions.

How Do I Solve a McKinsey Case Interview?

Below, we’ll walk through the seven steps of a McKinsey case interview that was presented in the previous section to show you how you should solve a McKinsey case interview.

1. Understanding the case background

The case interview will begin with the interviewer giving you the case background information. Let’s say that the interviewer reads you the following: 

Interviewer : Our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages, such as sodas, juices, sports drinks, and teas. They have annual revenues of roughly $30 billion and an operating margin of roughly 30%. Coca-Cola is looking to grow and is considering entering the beer market in the United States. Should they enter?

As the interviewer reads this, take notes. It is important to understand what the objective of the case is and keep track of information.

One strategy for taking notes effectively is to turn your paper landscape and draw a vertical line to divide your paper into two sections. The first section should be roughly two-thirds of the page while the second section will be one-third of the page.

Take notes in the second section of your page.

After the interviewer finishes giving the case background information, confirm that you understand the situation and objective. Provide a concise synthesis like the following:

You : To make sure I understand correctly, our client, Coca-Cola, is a large manufacturer and retailer of non-alcoholic beverages. They are looking to grow and our objective is to determine whether or not they should enter the U.S. beer market.

Interviewer : That sounds right.

Make sure your synthesis is concise. You do not want to regurgitate verbatim everything that the interviewer has said. Only mention the most important pieces of information.

You should also make sure you verify the objective of the case. Answering or solving the wrong case objective is the quickest way to fail a case interview.

2. Asking clarifying questions

Next in the case interview, you’ll have the opportunity to ask questions before you begin thinking about how to solve the case.

At this point, only ask questions that are critical for you to fully understand the case background and objective. You’ll be able to ask more questions later.

You might ask a few questions like the following:

You : Is Coca-Cola looking to specifically grow revenues or profits?

Interviewer : Coca-Cola wants to grow profits.

You : Is there a particular financial goal or metric Coca-Cola is trying to reach within a certain time frame?

Interviewer : They are looking to grow annual profits by $2 billion within 5 years.

You : Great. Those are all the immediate questions I have for now.

3. Structuring a framework

After you understand the case background and objective of the case interview, lay out a framework of what areas you want to look into in order to answer or solve the case.

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

When creating a framework, it is completely acceptable to ask the interviewer for a few minutes of silence to write out a framework.

You : Would you mind if I take a few minutes to structure my thoughts and develop a framework to tackle this case?

Interviewer : Of course, go ahead.

For this case example, what do you need to know in order to help Coca-Cola decide whether or not they should enter the beer market?

You might brainstorm the following questions:

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

This is not a very structured way of tackling the case, so organize these ideas into a framework that has 3 – 4 broad areas, also called “buckets”, that you want to investigate.

An easy way to develop these buckets is to ask yourself, what 3 – 4 things must be true for you to 100% recommend that Coca-Cola should enter the beer market.

In an ideal world. These four things would need to be true:

• The beer market is an attractive market with high profit margins
• Competitors are weak and Coca-Cola will be able to capture significant market share
• Coca-Cola has the capabilities to produce an outstanding beer product
• Coca-Cola will be extremely profitable

You can rephrase these points to be the broad categories in your framework.

Next, let’s add a few bullets under each category to give more detail on exactly what information we need to know to decide whether Coca-Cola should enter the beer market.

This entire process of brainstorming ideas and developing a structured framework should only take a few minutes.

For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

Now that you have your framework, turn your paper to face the interviewer and walk them through it.

You : To decide whether or not Coca-Cola should enter the market, I want to look into four main areas.

One, I want to look into the beer market attractiveness. Is this an attractive market to enter? I’d want to look into areas such as the market size, growth rate, and profit margins.

Two, I want to look into the beer competitive landscape. Is this market competitive, and will Coca-Cola be able to capture meaningful market share? I want to look into questions such as the number of competitors, how much market share each competitor has, and whether competitors have any competitive advantages.

Three, I want to look into Coca-Cola’s capabilities. Do they have the capabilities to succeed in the beer market? I want to look into things such as whether they have the expertise to produce beer, whether they have the distribution channels to sell beer, and whether there are any existing synergies they can leverage.

Four, I want to look into expected profitability. Will Coca-Cola be profitable from entering the beer market? I want to look into areas such as expected revenues, expected costs, and how long it would take to break even.

The interviewer might ask a few questions on your framework, but will otherwise indicate whether they agree or disagree with your approach.

4. Starting the case

McKinsey case interviews are interviewer-led. So, the interviewer will propose which area of your framework they would like to dive deeper into. They might say something like the following:

Interviewer : Your framework makes sense to me. Why don’t we start by estimating the size of the U.S. beer market.

5. Solving quantitative problems

Expect to perform calculations and analyze charts and graphs during your case interview.

Market sizing questions are one type of quantitative question you may get asked. Let’s say the interviewer asks you:

Interviewer : What is the market size of beer in the U.S.?

Most candidates jump right into the math, stating the U.S. population and then performing various calculations. Doing math without laying out a structure often leads to making unnecessary calculations or reaching a dead-end.

Laying out an upfront approach helps avoid these mistakes and demonstrates that you are a logical, structured thinker.

For this market sizing problem, you could structure your approach in the following way:

• Start with the U.S. population
• Estimate the percentage that are legally allowed to drink alcohol
• Estimate the percentage that drink beer
• Estimate the frequency in which people drink beer
• Estimate the average price per can or bottle of beer

Multiplying these steps together gives you the answer. By laying out an approach up front, the interviewer can easily understand how you are thinking about the problem. With the right structure, the rest of the problem is simple arithmetic.

Sometimes the interviewer will give you numbers to use for these calculations. Other times, you’ll be expected to make assumptions or estimates.

When performing your calculations, make sure to do them on a separate sheet of paper. Calculations often get messy and you want to keep your original paper clean and organized.

A sample answer to this question could look like this:

You : To estimate the market size of beer in the U.S., I’m going to start with the U.S. population. Then, I’ll estimate the percentage that are eligible to drink alcohol. I’ll then estimate the percentage of the remaining population that drinks beer.

If we take this and multiply it by the frequency in which people drink beer and the average price per can or bottle of beer, we will find an estimate for the market size. 

Does this approach make sense to you?

Interviewer : Makes sense to me.

You : Great. I’ll assume the U.S. population is 320M people. Assuming the average life expectancy is 80 years old and an even distribution of ages, roughly 75% of the population can legally drink alcohol.

This gives us 240M people. Of these, let’s assume 75% of people drink beer. That gives us 180M beer drinkers.

Let’s say on average, a person drinks five beers a week, or roughly 250 beers per year, assuming roughly 50 weeks per year.

This gives us 180M * 250 = 45B cans or bottles of beer.

Assuming the average can or bottle of beer costs $2, this gives a market size of $90B.

You should not only answer the question, but tie the answer to the case objective.

In other words, how does knowing the U.S. market size of beer help you decide whether or not Coca-Cola should enter the market?

You could say something like the following:

You : Given that Coca-Cola has annual revenues of $30B, a $90B beer market represents a massive opportunity. The market size makes the beer market look attractive, but I’d like to understand if beer margins are typically high and determine how much market share Coca-Cola could realistically capture.

6. Answering qualitative questions

In addition to asking quantitative questions during the case interview, the interviewer will also ask qualitative questions.

One type of qualitative question you could get asked are brainstorming questions. For example, the interviewer might ask:

Interviewer : What are the barriers to entry in the beer market?

Most candidates answer by listing ideas that immediately come to mind:

• Brewing equipment
• Beer production expertise
• Distribution channels

This is a highly unstructured way of answering the question. Make sure to use a simple structure to organize your thoughts.

A simple structure, such as thinking about barriers to entry as either economic barriers or non-economic barriers, helps facilitate brainstorming and demonstrates logic and structure.

With this structure, you might come up with the following answer:

You : I’m thinking of barriers to entry as economic barriers and non-economic barriers. Economic barriers include things such as equipment, raw material, and other capital. Non-economic barriers include: beer brewing expertise, brand name, and distribution channels.

Looking at these barriers, I think it will take Coca-Cola a lot of work to overcome these barriers. While Coca-Cola does have a brand name and distribution channels, they lack beer brewing expertise and would have to buy a lot of expensive equipment and machinery. These barriers make entering the beer market difficult.

7. Delivering a recommendation

You’ve done a ton of work so far in the case interview and now it is time to put everything together into a recommendation.

Throughout the interview, you should have been making notes of key takeaways after each question you answer.

Take a look at the key takeaways you’ve accumulated so far and decide whether you want to recommend entering the beer market or not entering the beer market:

• The U.S. beer market size is $90B compared to Coca-Cola’s annual revenue of $30B
• The beer market profit margins are 10% compared to Coca-Cola’s average margin of 30%
• The beer market is highly concentrated across all categories
• Barriers to entry are moderate
• There are some synergies with existing production

There is no right or wrong recommendation, as long as you support your recommendation with reasons and evidence.

Regardless of what stance you take, make sure you have a firm recommendation. You do not want to be flimsy and switch back and forth between recommending entering the market and not entering the market.

Secondly, make sure your recommendation is clear and concise. Use the following structure:

• Clearly state what your recommendation is
• Follow that with the 2 - 3 reasons that support your recommendation
• State what potential next steps would be to further validate your recommendation

The conclusion of the case might look like the following:

Interviewer : Let’s say that you bump into the CEO of Coca-Cola in the elevator. He asks you what your preliminary recommendation is. What do you say?

You : I recommend that Coca-Cola should not enter the U.S. beer market for the following three reasons.

One, although the market size is fairly large at $90B, the margins for beer are just 10%, significantly less than Coca-Cola’s overall operating margin of 30%.

Two, the beer market is very competitive. In all beer segments, market share is concentrated among a few players, which implies high barriers to entry. Coca-Cola lacks beer brewing expertise to produce a great product that existing incumbents have.

Three, there are not that many production synergies that Coca-Cola can leverage with its existing products. Coca-Cola would need to buy new equipment, source new raw materials, and provide new training to employees, which will be time-consuming and costly.

For next steps, I want to look into Coca-Cola’s annual expected profits if they were to enter the U.S. beer market. I hypothesize that they will be unable to achieve an increase in annual profits of $2B within five years, but I’d like to confirm this through further analysis.

What are Examples of McKinsey Case Interviews?

The best place to find examples of McKinsey case interviews is on their official website. There, they have provided four case interview examples that you can practice along with:

• Diconsa case interview practice :   Non-profit case focused on deciding whether to leverage a chain of convenience stores to deliver basic financial services to inhabitants of rural Mexico. Great practice case for the non-profit sector.
• GlobaPharm case interview practice :  Acquisition case focused on deciding whether a large pharmaceutical company should acquire a smaller startup. This case has very difficult math calculations that you can practice.
• Electro-light case interview practice :  New product launch case focused on deciding whether a beverage company should launch a new sports drink. Outstanding case to practice interpreting various charts and graphs.
• National Education case interview practice : Non-profit case focused on helping an Eastern European country’s Department of Education improve their school system. Another great practice case for the non-profit sector.
• Beautify case interview practice : Evaluate whether a beauty products company should be training in-store beauty consultants in the use of virtual channels to connect with customers
• Talbot trucks case interview practice : Determine whether to invest in the production and sale of electric trucks

McKinsey Phone Case Interview Differences

The McKinsey phone interview consists primarily of a slightly shorter, 30-minute case interview. 

The major differences between a McKinsey phone interview and in-person interview are that the phone interview is shorter, has an easier case interview with less depth, does not have complicated exhibits, and lacks qualitative discussion.

  1. Shorter interview length

The case interview in a McKinsey phone interview is roughly 30 minutes, shorter than the typical 40- to 60-minute McKinsey case interview.

2. Easier case interview with less depth

The case interview in a McKinsey phone interview will be a more straight-forward business problem, such as:

• Why is profitability declining?
• Should we enter this new market?
• Should we acquire this company?

It is unlikely that you’ll get an unusual or atypical business situation.

Additionally, because the McKinsey phone interview is only 30 minutes, the case will be covered in less depth. There will either be fewer questions asked during the case or the questions asked will be very surface-level, not requiring deeper dives.

3. Does not have complicated exhibits

Given that the McKinsey phone interview is only 30 minutes, there will likely not be time for the interviewer to hand you several different exhibits with complicated charts and graphs. You’ll likely be given a simpler quantitative problem to solve.

4. Lacks qualitative discussion

In a typical case interview, the interviewer will ask a few qualitative questions to start a discussion to assess your business acumen.

Given that the McKinsey phone interview is only 30 minutes, there will likely only be enough time for you to solve the main quantitative problem and perhaps briefly answer one qualitative question.

Therefore, you’ll be less tested on business knowledge and principles during the McKinsey phone interview.

How to Prepare for McKinsey Case Interviews

There are seven steps to preparing for McKinsey case interviews.

1. Understand what a case interview is

The first step in preparing for McKinsey case interviews is to understand exactly what case interviews are.

When you are familiar with what case interviews are, it is important to know what a great McKinsey case interview performance looks like.

Knowing what a great McKinsey case interview performance looks like will facilitate how quickly you learn case interview strategies in the next step.

Before continuing onto the next step, you should be familiar with:

• The overall objective of a case interview
• The structure and flow of a case interview
• The types of questions you could get asked
• What a great case interview performance looks like

2. Learn the right strategies

Now that you have sufficient background knowledge, the next step in preparing for McKinsey case interviews is to learn the right strategies to build good case interview habits.

It is much more effective to learn the right case strategies the first time than to learn poor strategies and try to correct them later.

The quickest, most efficient way to learn these strategies is to go through our Comprehensive Case Interview Course .

If you prefer reading case interview prep books instead, the three I recommend are:

• The Ultimate Case Interview Workbook
• Case Interview Secrets

Hacking the Case Interview provides strategies on exactly what to do and what to say in every step of the case interview. It is a concise and straight to the point guide. I recommend this book as the first book to read for beginners.

Case Interview Secrets teaches core concepts such as the issue tree , drill-down analysis, and a hypothesis driven approach. It illustrates these concepts through stories and anecdotes. If you have read Hacking the Case Interview, I recommend also reading this book to get perspectives from a second author. Check out our full review of Case Interview Secrets .

Case in Point provides a ton of specific and complex frameworks. However, you likely won’t be using many of these in an actual case interview because many of them are overly complex and specific. If you have time, it may be useful to skim through this book. Check out our full review of Case in Point .

At the bare minimum, read either the first or second book. If you have the time, read the first two books so that you can get strategies from two different authors.

Make sure to spend sufficient time learning the right strategies before starting to practice cases. It is ineffective to practice cases if you have no idea what strategies to practice and refine.

Before moving onto the next step, you should at least have strategies for the following parts of a case interview:

• Developing unique and tailored frameworks
• Solving quantitative problems
• Answering qualitative questions
• Delivering a recommendation

3. Practice 3-5 cases by yourself

Once you have learned the right strategies, the next step in McKinsey case interview prep is to practice.

When practicing case interviews, it is usually better to practice with a case interview partner than to practice by yourself . Casing with a partner better simulates the real case interview experience.

However, when you are just starting to practice, I recommend doing the first 3 – 5 cases by yourself.

There are three reasons for this:

• You can get the hang of the case interview structure and format much more quickly working by yourself rather than having to wait to schedule a time with a partner
• There are many aspects of case interviews that you can practice without a partner, such as structuring a framework and solving quantitative problems. You can get much more practice working through these parts by yourself
• You may have difficulty finding a case interview partner if you are a complete beginner. Without having done any cases, you likely won’t know how to properly give a case or provide good feedback

4. Practice 5-10 cases with a partner

The next step in preparing for McKinsey case interviews is to case with a partner.

Casing with a partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner.

When practicing cases with a partner, ensure you are spending enough time after cases to deliver feedback.

For a case that takes around 30 – 40 minutes, spend at least 15 – 20 minutes for feedback. Much of your learning and improvement will come from these feedback sessions.

Do not move onto the next step until you have done at least 5 – 10 cases and are beginning to feel comfortable with case interviews.

5. Practice with a former or current consultant

At this point, I highly recommend asking former or current consultants to give you a practice case. This will significantly help you prepare for case interviews.

Doing a mock case with a former or current consultant is highly advantageous because they know exactly how to run cases and give feedback. You’ll receive incredibly helpful feedback that your previous case partners likely missed.

If you feel that you are plateauing with your case partner, that is a sign you should do a mock case interview with a former or current consultant.

You can find former or current consultants among:

• People you met during the consulting recruiting process
• Your broader LinkedIn network

I would not ask a consultant that is involved with the consulting recruiting process for a case too prematurely. Although these practice cases are not evaluative, some firms will actually make note of how well you perform during the practice case.

At this point, you will have accumulated a long list of improvement areas from all of the different people you have cased with.

6. Work on your improvement areas

In this step of preparing for McKinsey case interviews, you will work on strengthening and fine-tuning your improvement areas. Examples of common improvement areas include:

• Creating a more complete and mutually exclusive framework
• Performing math calculations quicker or more smoothly
• Providing more structure to your qualitative answers
• Leading the case more proactively
• Delivering a more succinct recommendation

Try to focus on improving one thing at a time. This is much more effective than trying to improve everything at once.

For some areas, such as math, it will be better to work independently. For other areas, such as learning to proactively lead the case, it will be better to work with a case partner.

If you are looking for more cases, look at the resources listed in step four. If you are looking for specific drills or practice problems for a particular part of a case interview, check out The Ultimate Case Interview Workbook .

Do not move onto the next step until you have finished working on all of your improvement areas.

7. Stay sharp

If you have progressed this far, congratulations! You have almost finished preparing for McKinsey case interviews.

Once you feel that you have no more improvement areas to work on, the key is to not burn yourself out by doing too many unnecessary cases.

While each case that you do makes you slightly better, there is a point when doing too many cases can create case fatigue right before your interview. Case fatigue can negatively impact your interview performance.

On the other hand, you also don’t want to go weeks without having done a case. You may end up forgetting strategies or become rusty and slow.

Once you have achieved case mastery, I recommend doing no more than 2 cases per week in the weeks leading up to your interview. This ensures that you remain sharp for case interviews, but don’t have case fatigue.

What are Recommended Resources for McKinsey Case Interviews?

To prepare for McKinsey case interviews, you can use a variety of different case interview prep books, online courses, and coaching. We'll cover each of these different categories of resources in more detail.

McKinsey Case Interview Prep Books

Case interview prep books are great resources to use because they are fairly inexpensive, only costing $20 to $30. They contain a tremendous amount of information that you can read, digest, and re-read at your own pace.

Based on our comprehensive review of the 12 popular case interview prep books , we ranked nearly all of the case prep books in the market.

The three case interview prep books we recommend using are:

• Hacking the Case Interview : In this book, learn exactly what to do and what to say in every step of the case interview. This is the perfect book for beginners that are looking to learn the basics of case interviews quickly.
• The Ultimate Case Interview Workbook : In this book, hone your case interview skills through 65+ problems tailored towards each type of question asked in case interviews and 15 full-length practice cases. This book is great for intermediates looking to get quality practice.
• Case Interview Secrets : This book provides great explanations of essential case interview concepts and fundamentals. The stories and anecdotes that the author provides are entertaining and help paint a clear picture of what to expect in a case interview, what interviewers are looking for, and how to solve a case interview.

McKinsey Case Interview Courses

Case interview courses are more expensive to use than case interview prep books, but offer more efficient and effective learning. You’ll learn much more quickly from watching someone teach you the material, provide examples, and then walk through practice problems than from reading a book by yourself.

Courses typically cost anywhere between $200 to $400.

If you are looking for a single resource to learn the best McKinsey case interview strategies in the most efficient way possible, enroll in our comprehensive case interview course .

Through 70+ concise video lessons and 20 full-length practice cases based on real interviews from top-tier consulting firms, you’ll learn step-by-step how to crush your McKinsey case interview.

We’ve had students pass their McKinsey first round interview with just a week of preparation, but know that your success depends on the amount of effort you put in and your starting capabilities.

McKinsey Case Interview Coaching

With case interview coaching, you’ll pay anywhere between $100 to $300 for a 40- to 60-minute mock case interview session with a case coach. Typically, case coaches are former consultants or interviewers that have worked at top-tier consulting firms.

Although very expensive, case interview coaching can provide you with high quality feedback that can significantly improve your case interview performance. By working with a case coach, you will be practicing high quality cases with an expert. You’ll get detailed feedback that ordinary case interview partners are not able to provide.

Know that you do not need to purchase case interview coaching to receive a consulting job offer. The vast majority of candidates that receive offers from top firms did not purchase case interview coaching. By purchasing case interview coaching, you are essentially purchasing convenience and learning efficiency.

Case interview coaching is best for those that have already learned as much as they can about case interviews on their own and feel that they have reached a plateau in their learning. For case interview beginners and intermediates, it may be a better use of their money to first purchase a case interview course or case interview prep book before purchasing expensive coaching sessions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.

Case Interview Examples (2024): A Collection from McKinsey and Others

Last Updated on January 11, 2024

Whenever you prepare for case interviews, you have to practice as realistically as possible and mimic the real case study interview at McKinsey , BCG , Bain , and others. One way to do this and make your preparation more effective is to practice real cases provided by the firms you apply to.

It will help you to understand what the differences are across firms, how they structure and approach their cases, what dimensions are important to them, and what solutions they consider to be strong.

Below is a steadily expanding selection of real case interview examples provided by different management consulting firms.

McKinsey Case Interview & PEI - 6 Things You Need to Know

• Last Updated January, 2024

Rebecca Smith-Allen

Former McKinsey Engagement Manager

If you’re interested in a career in management consulting, McKinsey & Company is probably on your list of firms to apply to. It’s the oldest consulting firm, established in 1926 by James McKinsey, a University of Chicago professor and expert in management accounting.

Today, the firm employs 30 thousand professionals working in 130 cities around the world. McKinsey regularly ranks at the top of lists of strategy consulting firms and is hired by businesses, governments, and non-profit organizations to help solve their toughest problems.

It’s difficult to get a job offer from McKinsey.

Like its top management consulting competitors, Bain and BCG, McKinsey typically hires only 1% of candidates who apply. In particular, McKinsey case interviews are tough to crack…but not impossible.

If you’re interested in trying to beat the odds, this article will tell you what you need to know to succeed. We’ll tell you:

What’s different about McKinsey,

6 things candidates recruiting with McKinsey should know,

We’ll provide a mock McKinsey case interview video, and

Provide tips on acing your McKinsey interview.

Let’s get started!

What’s Different About McKinsey? 6 Things Candidates Should Know

1. consultants are hired for either the generalist track or a specialist track.

Generalists at McKinsey are consultants who could be staffed to help clients in any industry and dealing with any type of business problem. Specialists are consultants with a particular area of expertise.

Areas of specialization within McKinsey  include digital and advanced analytics, marketing and sales, business turn around, operations,  software development and design, and implementation.

2. Consultants Work On-Site At The Client 4 Days A Week.

Most consultants travel a lot and at McKinsey, this is definitely the case. Consider whether regular plane flights and hotel stays are right for you.

3. McKinsey Cases Are Interviewer-Led Rather Than Candidate-Led.

Candidates are still expected to identify key issues to be addressed to solve the business problem presented by their interviewer and outline a plan to explore these issues. After they do that, their McKinsey interviewer is likely to tell the candidate which issue they’d like to discuss first. Other management consulting firms, like Bain and BCG typically let candidates steer their case interview.

4. Interviewers Assess Fit As Part Of Every Interview With Personal Experience Interview (PEI) Questions.

While all strategy firms ask candidates Consulting Behavioral Interview Questions  to assess their fit with their firm, many have one interviewer focus entirely on fit while others focus entirely on a case study question. 

McKinsey interviewers split their interview time between the case and PEI in every interview.

5. McKinsey Looks For Personal Impact And Entrepreneurial Drive In Candidates.

This is in addition to the structured problem solving and leadership skills that McKinsey, as well as other top consulting firms, look for in candidates.

6. Mckinsey Recruiting Uses Solve - a Gamified Digital Assessment.

McKinsey’s Solve Game was launched to broaden the firm’s reach to find the best talent regardless of geography as well as provide deeper insight into candidates’ problem-solving skills.

Keep reading for a deeper dive into these topics.

Generalist versus Specialist Track Roles

When the management consulting industry was first founded, simply having an MBA and expertise in solving business problems was enough to set a consultant apart. Consultants hired by McKinsey could expect to be staffed on a case in any industry and solving any type of problem.

To help clients solve these types of business problems effectively, McKinsey hires people with years of experience in functional specialties. These include advanced analytics, marketing and sales, business turn around, operations, software development and design, and implementation.

Specialists work alongside generalists on projects to leverage their functional expertise across the work of the team. The specialist practices are growing faster than generalist roles and get fewer applications, so if you have the right kind of expertise and apply to the practice, you may have a better chance of landing an interview.

How McKinsey Interviews Differ from Bain and BC

There are two main ways that McKinsey’s interviews differ from those of other top management consulting firms. McKinsey uses interviewer-led case interviews while other firms use candidate-led case interviews.

In the “fit” portion of the interview, McKinsey uses the personal experience interview and each interviewer you meet with in all rounds will assess fit.

Interviewer-led Cases

At the start of any McKinsey case study, candidates need to go through 4 phases to solve the business problem the interviewer has given them in a structured manner: the opening, structure, analysis, and closing. 

In a candidate-led case interview, candidates will pick which part of the problem they want to dive into first and proceed with it. In McKinsey’s interviewer-led cases, the interviewer will pick the first part of the business problem they want the candidate to address.

Is the interviewer-led case interview easier or harder than the candidate-led one?

If you’ve structured the business problem well, breaking the problem down into the MECE  issues that require further analysis, it should not matter who picks which aspect of the problem to address first. What is helpful is knowing what to expect in your case interview so that you don’t start down one path just to be redirected by your McKinsey interviewer.  You don’t want anything to throw you in the middle of your case!

For more information on these 4 phases of answering a case interview question, see  Case Interview Prep .

Behavioral Interview Questions - The McKinsey PEI

As mentioned above, fit or personal experience interview (PEI) questions are part of every McKinsey interview. 

How else is the PEI different?

While other top management consulting firms focus on bringing the best creative problem-solving to their clients’ problems (BCG is notable here), McKinsey is interested in candidates’ personal impact and entrepreneurial spirit.

McKinsey interviewers look for these characteristics in answers to PEI questions. Because of this, it’s good to have some insight into why the firm thinks these characteristics are important.

Personal Impact

McKinsey says this about personal impact on its career website:

McKinsey does not want to create PowerPoint presentations with elegant solutions that sit on an executive’s shelf, not implemented.

Personal impact means that McKinsey consultants work shoulder-to-shoulder, on-site with client executives, developing solutions that don’t just solve a business problem in theory but also do it in practice. This can require facing resistance to change in the client’s organization head-on and persuading people to reassess long-held beliefs.

During the PEI, questions like the following will be asked to assess personal impact:

•   Tell me about a team you worked on when you needed to change someone’s mind on a topic that was important to them, or
•   Tell me about a time when you needed to rely on your communication skills to solve a difficult interpersonal situation.

This belief that personal impact is key to developing an implementable solution is what drives McKinsey consultants to spend 4 days a week on client site.

Entrepreneurial Drive

McKinsey says this about entrepreneurial drive on its career website:

McKinsey doesn’t hire consultants who can only implement solutions they’ve seen in previous businesses. They want people who are willing to try new things, take solutions to new industries or new types of problems.

The McKinsey problem solving approach treats each client problem as unique. Each solution should push thinking about best-practices.

In addition to personal impact and entrepreneurial drive, McKinsey also assesses leadership using the PEI. We won’t address this in detail because this is similar to other consulting firms, but you can find more about how McKinsey assesses leadership in our page on  McKinsey PEI Questions.

It also includes What McKinsey Is Looking For and provides a list of 11 Common PEI Questions.

The McKinsey Interview Process - Traditional and Recent Changes

The traditional recruiting process.

For years, McKinsey focused on a group of core schools to find new analyst (undergraduate hires) and associate (MBA hires) candidates. 

While the firm now recruits from a broader set of schools as well as more diverse candidates, recruiting at these core schools still starts in much the same way. McKinsey consultants conduct on-campus presentations and coffee chats to talk to potential candidates about what it’s like to work in the management consulting industry and at McKinsey, in particular.

If the firm hosts an event at your campus, you should attend to make personal connections and to find out first-hand if a career at McKinsey is right for you. If there are no events at your school or if you’re already employed, check out the company’s career site for articles and videos that will tell you what it’s like to work at McKinsey and what it takes to get an offer.

Candidates submit their resumes (and optional cover letters) to the firm’s recruiting department via their school’s department of career services and on the firm website. Candidates who are invited to interview typically have their first round interviews on campus.

During first round interviews, candidates meet with 2 interviewers back-to-back. Candidates who pass first round interviews are invited to a McKinsey office for second round interviews.

In second round interviews, candidates meet with 3 interviewers. Unless a candidate’s interviewers are split in their decision, second round interviews are also final round interviews.

In each round of interviews, McKinsey interviewers walk candidates through a business problem and asks a series of  McKinsey PEI Questions , aimed at evaluating their potential fit with the organization. 

The Recruiting Process for Candidates at Non-core School and Experienced Hires

Candidates from non-core schools submit their resumes (and optional cover letters) directly to the recruiting department of the 3 offices they’d like to work in.

If they are invited to interview, candidates who live relatively close to a McKinsey office will be invited for in-person first round interviews. Others will be asked to do their first round McKinsey interviews via video conference.

Candidates already working in another industry or those working at another consulting firm submit their resumes (and optional cover letters) directly to the recruiting department of the three offices they’d like to work in. They will typically have a phone interview before the “first round” of in-person interviews.

In both cases, once candidates are passed to second round interviews the recruiting process is the same as for core school candidates.

Solve, The McKinsey Problem Solving Game

McKinsey is reaching out to more candidates outside of their traditional core schools to diversify its recruiting. As part of that, it’s launched  Solve , an online game  that assesses candidates’ problem-solving skills.  Solve is both more fun and gives candidates from non-core schools a better shot at getting a McKinsey interview than they’ve had in the past.

Example McKinsey Case Interview - Video

Below, we have 4 videos in which My Consulting Offer founder, Davis Nguyen, walks you  through each segment of a McKinsey case interview from beginning to end. 

Mock McKinsey Case Interview - Opening the Case

The key thing to do in the opening of a McKinsey case study is to repeat back the question so you’re sure you understand the problem you are solving. Then, ask questions to begin to get more information.

Mock McKinsey Case Interview - Structuring the Case

In the structure section of McKinsey Case Interviews, create a MECE list of important issues you will analyze to solve the client’s problem.

Mock McKinsey Case Interview - The Case Analysis

In the analysis section of a McKinsey case study, you’ll need to do analysis to evaluate the best option for your client. This may require interpreting data from charts or graphs provided by your interviewer or doing calculations based on numbers you’re given.

Mock McKinsey Case Interview - Concluding the Case

In the conclusion of McKinsey case interviews, you’ll need to pull your analysis together into a persuasive recommendation for the client. Restate the question you were asked to solve, lay out key findings from each section of your case structure, and show how your analysis points to the course of action the client should take.

Now that you’ve watched our sample McKinsey case interview, you should be ready to start practicing for your own interviews. 

Here are 5 tips on making the most of your preparation time:

5 Tips on Acing Your McKinsey Interview

• Practice casing with another person. Answering case interview questions does not come naturally and it is not enough to practice on your own since casing requires having a dialogue. Give yourself as much time to practice mock interviews as possible by starting early.
• Record yourself during mock interviews  using your computer or phone. Study these videos to see how you can improve your performance in each phase of the case interview. Aim to make your answers more fluent and conversational.
• Practice sample McKinsey interview-led case interviews. Use  McKinsey-specific case interview examples  below to make sure you’re not just familiar with cases, but with McKinsey cases. Make sure you are comfortable with being redirected at times. 
• Brainstorm several  stories to answer common personal experience interview questions. You can find a list of these common questions here .
• Find out more about the  McKinsey Solve Game  before you take it. 

After reading this article, you should have a good understanding of what McKinsey’s recruiting process looks like and how McKinsey case interviews are different from other management consulting firms.
