Think On Your Feet First

You should only ask leadership assistance only after youve thought well about the problem.

Just pause for a second and think: would you be more ready to help someone who really tries their best at the job, or someone who does nothing and relies solely on you?

The same thing is true in consulting work, and even in case interviews: the interviewer will assist you if you can deliver well-informed opinions.

With that said, asking without thinking first is a very common mistake in case interviews, which you can see in the numerous examples from our End-to-End Secrets Program.

A Guide To Tackling Case Interviews With Ease

If youâre interested in consulting, youâve almost certainly heard of a case interview â a job interview in which you are presented with, and asked to solve, specific business challenges.

Inside The Case Interviewers Mind Consulting Culture

The best way to impress your consulting interviewer is to act like a consultant. And to do that, you need to know what goes on inside their mind both the conscious and unconscious then install it into your own personality.

In this chapter, Ill guide you through 15 ingredients that make up a consulting mind. However, I wont tell you how to apply this in case interviews because it will sound fake what you need is to immerse yourself in a consulting environment, and incorporate these ingredients into your own mindset.

    Our Case Interview Method

    You can start reading about our Problem Driven Structure approach to case cracking and the building blocks that accompany it our website articles. However, the best place to learn everything you need to know about these tools, as well as all the background knowledge and skills you need to excel in case interview, is in our MCC Academy course.

    Our MCC Academy case interview course was developed with a single goal in mind to help candidates succeed by teaching them to think, act and communicate like a world-class strategy consultant. After completing our course, youll be equipped not only to ace the interview process, but also to hit the ground running on day one of the job.

    The idea of getting hired by acquiring the fundamental skills associated with the job might seem obvious. However, our approach is actually in stark contrast to the old-fashioned case interview systems you have probably have run into already.

    These other methods simply have you memorise perhaps a dozen standard frameworks. This shortlist of generic recipes is supposed to allow you to answer any case question the interviewer comes up with. This is in spite of the fact that that cases will be based on real engagements, where major firms were forced to call in consultants as they couldnt solve the problem in-house In short, frameworks are unlikely to give you correct answers.

  • Should You Learn Case Interview Frameworks By Heart

    Be aware that framework templates were applicable 10 years ago, the era of Victor Cheng and Case in Point. McKinsey and other top-tier firms have long caught up on this and the cases you will get during the interviews are tailored in a way to test your creativity and ability to generate insights, not remember specific frameworks.

    In fact, it will hurt you when you try to use a framework on a case that calls for a completely different approach. Also, it gives a false sense of security that will translate to stress once you figure out how your approach wont work during the real interview We have seen this so many times

    Your goal should be to learn how to build custom issue trees and frameworks, interpret charts, and perform math no matter the context, industry, or function of the case. Our approach teaches you this and trains your ability to come up with deep, broad, and insightful structures for each case individually.

    Now, if you come from a non-business background, it certainly does not hurt to glance over the classic frameworks once to become familiar with the terms and phrases as long as you are aware that their usefulness ends there.

    Where And Why Case Interviews Are Used

    From the clients brief, through the analyses, all the way to the recommendation, case interviews simulate the job itself. MBB firms use the case interview as its a statistically-proven predictor of how well a candidate will do on the job.

    Top consulting firms, however, did not invent the case interview. They only adapted it from the concept of the Case Study Teaching Method, which was invented at Harvard Law School in the late 19th century. When they were created, top management consultancies mirrored their organizations on law firms, creating many parallels between law and consulting.

    Today, case interviews are used, as well, by employers outside of management consulting including spaces such as tech, financial services, or nonprofits, particularly for the recruitment of employees involved in shaping strategic initiatives. The following employers are known to use case interviewing:

    This trend is expected to continue as the ranks of management consultant alumni grow and their methods spread to the industries they join.

    When To Do A Case Study

    Interviewing with McKinsey: Case study interview

    A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

    Case studies are often a good choice in a thesis or dissertation. They keep your project focused and manageable when you dont have the time or resources to do large-scale research.

    You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

    What Is A Framework In A Case Interview

    A case interview structure is used to break the problem you are trying to solve for the client down into smaller problems or components. It is the roadmap you establish at the beginning of the interview that will guide your problem-solving approach throughout the case.

    A structure usually consists of a top-layer and several sub-levels.

    To illustrate, the most common and basic structure you might find in some preparation cases is:

    Profit = Revenue Cost

    This high-level structure is used for profitability cases when you are tasked to solve an issue with the clients profit development. For instance, client profit has gone down over the last year and we are not sure why that is the case.

    The structure above represents the top-level. In order to analyze the problem, you would need to go deeper and figure out what sub-levels influence the variables you are looking at.

    It is important to tailor the structure and associated sub-levels to the case questions. Framework templates were en vogue 5-10 years ago and consulting firms have moved away from asking generic cases that would fit the frameworks taught by Case in Point or Victor Cheng .

    In terms of format, the best-practice approach to structuring a case is to build an issue tree with branches, which are split into several sub-branches. To stick with our example from above, check out our profitability framework below.

    The Seven Types Of Case Interview Questions

    Case interview: the ultimate guide (2020)  IGotAnOffer

    All case interviews from the top consulting firms consist of the same 7 types of case interview questions.

    Here they are:

  • Case Interview Recommendation – Question

  • Lastly, there is the occasional: Case Interview Market Sizing – Question

    So what makes the great candidates different from all the other merely good candidates ?

    The ones who land offers simply learned and internalized how to consistently outperform in each type of case interview question.

    In other words, if you know how to outperform during each type of question, you by virtue end up outperforming on the overall case.

    Its this reason why many of our students have landed offers not just at McKinsey, not just at BCG, not just at Bain, but have landed offers from ALL three firms.

    What we call hitting the MBB Trifecta!

    Heres a recent quote from one of our students:

    I ended up getting offers from all three firms – McKinsey, Bain, and BCG.. Now just have to choose! Thanks Brian!

    This particular student was actually a consulting club officer at a top 5 MBA program.

    Despite the amount of career service and consulting club resources, students often get lost in separating the signal from the noise.

    More importantly, the majority of these resources will not push you to great.

    So now, lets dive in and understand what each of these 7 types of questions are in more detail. Youll also learn what we case interviewers look for in each.

    Preparation For Case Study Rounds In Interviews

    I’m applying for Salesforce roles and I have 3 years experience. And one of the rounds is case study round and I failed miserably two times that I got the opportunity. I don’t know how to prepare for those and what the things I should learn and improve my knowledge and how to present the solution. Can anyone guide me ?

    1st company gave me a case study where a watch company wants to implement Salesforce and asked me a presentation which I did and presented. 2nd company gave me a case study where I have to build a support system along with integrating the possible solutions to their webpage. For which I suggested either link webpages to Salesforce button or using Experience cloud. The interviewer told Experience cloud is a better solution and discussed the solution with me but decided not to proceed with my candidature.

    I don’t want to fail in more interviews.
