Best resources for McKinsey case interviews & PEI

Hello!

Indeed this is one of the risk of over-preparating, and it not only affects FIT but also the Business Case. People who over-prepare end up being rigid and not natural, and losing the "charm" and naturality that one should have in a conversation.

Think of the FIT part of the itnerview as if you were meeting your partner´s parents: you want to impress them, but also be nice, since you don´t want them to think of you as cocky or sharky. It´s the same thing!

Hope it helps!

Cheers,

Clara

Hi Justin,

I wrote a blog post here some time ago on that subject: https://www.quora.com/What-are-the-best-resources-to-prepare-for-McKinsey-case-interviews/answer/Robert-Steiner

For your convenience, please find it also copied here:

• "Case in Point" book by Marc Cosentino
• "Case Interview Secrets" book by Victor Cheng
• Victor Cheng youtube videos
• Case books from the well-know us universities which you can find here: https://masterthecase.com/case-interview-casebooks-top-mba/
• Of course - needless to say - PrepLounge
• "The Ultimate McKinsey PEI Prep" eBook which I put together to efficiently prepare my coaching candidates for McKinsey PEI questions, which you can find here: https://pei.consulting-case-interviews.com
• Recently I have added a blog with free expert advice on the McKinsey PEI where I am sharing some answers on the most common PEI questions that I receive from coaching candidates and which are worth sharing: https://pei.consulting-case-interviews.com/blog/
• Once you start feeling comfortable with solving cases in general, focus on being as structured as possible in every sentence you say and every answer you give ("ABS - always be structured"). This is especially important for McKinsey, as they are most picky when it comes to being structure in case interviews. For this, I wrote a distinct book with the most important frameworks and business concepts for case interviews (you can find it here: Case Interview Frameworks - http://cif.consulting-case-interviews.com/). This book not only gives you a short description and basic idea of the frameworks and concepts, but also a step-by-step guide on how to actually use and implement them (you would be surprised how many candidates don't have a clue about that!).

Edit: For McKinsey case interview practice, there is also a McKinsey case compilation available online (http://ebook.mckcasebook.com/).

Dear Justin!

First of all, I recommend you reading the McKinsey case book, which can help you better understand the whole interview mechanics and what happens behind the stage.

For PEI questions you can use a specific structure, which consists of 5 components:

1. Situation (background)

2. Problem (Complication)

3. Your approach (how did you manage this problem)

4. Results (Outcomes of your approach)

5. Your learnings (what you take from this situation)

If you can apply this framework to every of your PEI stories and communicate in a top-down way, you would definitely leave a great impression. For more details, feel free to approach me.

Good luck,

André
