I am new to case interviews. Any advice?

Question

I am new to PrepLounge and excited to immerse myself on this learning platform. I will be participating in case interviewing preps, and wanting to know as the "interviewer" what type of questions do/should be asking.

I have passed the initial assessments for Whitefield for the role of Policy Advisor.

I want to succeed and also support my peers in being successful the best way I can through these practice stimulations.

Any suggestions? Thanks in advance

Answer 1

First of all, great that you’re starting this journey; preparing for case interviews can be challenging, but also very rewarding and extremely useful throughout your career.

One important thing to keep in mind is that case interviews are not just a list of questions. They test a combination of skills, including:

Structured thinking and communication
Problem-solving and business judgment
Quantitative skills (math)
Creativity and hypothesis-driven thinking
Ability to synthesize and drive to a clear recommendation

As an “interviewer” in practice sessions, your role is not just to ask questions, but to guide the candidate and evaluate how they think, for example:

Are they structuring the problem clearly?
Are they asking relevant clarifying questions?
Are they connecting insights to the overall objective?
Are they communicating in a clear and logical way?

My suggested approach:

Start with one session with a professional coach. No need to commit to large packages; a single session at the beginning is enough to:
- Understand how to approach cases properly
- Get a clear prep plan tailored to you
- Benchmark your starting level
Then, put in the work consistently:
- Practice as many cases as possible
- Work with peers regularly
- If your budget allows, add periodic sessions with a coach to accelerate your progress and fix blind spots

Finally, remember that a big portion of the progress comes from consistency.

Hope this helps!

Hi there,

Best place to start: watch as many live case interview videos as you can. YouTube has loads of them — you'll get a feel for what good questions look like, how interviewers push on structure, and when to probe further.

If you look up my name on YouTube you'll find a few of mine as well — here's one: Digitization Case Framework Walkthrough. I also have cases on PrepLounge with video solutions linked directly to them — here's an example: Hot Wheels Case — with Video Solution

And two more:

Bain + BCG Hot Wheels - Part 2 WITH VIDEO SOLUTION | PrepLounge.com

BCG + Bain - Vets2U - Healthcare Based Case WITH VIDEO SOLUTION | PrepLounge.com

If you wait 1 more day, they'll be one on Youtube for this one as well: MBB - Climate Change Operations | PrepLounge.com

Watching real live cases is far more useful than any written guide for the interviewer role. Good luck!
