Hi there,

Q: Should you review all the cases you've ever done in the days leading up to the interview? Best way to do this efficiently?

I would not review all of them, just those where you made mistakes/had issues which hopefully you have tracked.

Good luck!

Hi there,

I think this is an interesting question that may be relevant for many people. I would be happy to share my thoughts on it:

  • First of all, you should have reviewed every case study you conducted right after, in order to ensure continuous improvement of your performance.
  • Moreover, while there might be marginal value added by reviewing all case studies before the interviews, I would not necessarily expect this to help you perform any better.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

Best,

Hagen

Hey,

If you haven't prepared a synthesis document with what you've learnt (concept, framework, etc.) from each case, my advice would be to review each case and spend 5-10 min to point out what you've learnt with each case (and ideally write it somewhere). If you've done many cases, just review the one you found the most difficult.

If you have a synthesis document you can use it instead of reviewing all cases.

Cheers,

Alexandre

Hi there,

it should be a gradual process. You reflect on your performance in each mock-up case you do and take your learnings you implement in the next mock-up you do - and so on.

Cheers,

Hi there,

I would not do this in the final days!

Rather, in the weeks/months leading up to the interview, periodically review your cases.

Review your notes that you took from the case (learnings, feedback, etc.), review the case itself, and, importantly, case others in cases that you struggled in.

You can do, but I'm not sure what you'd be getting out of it? Being able to case is being able to structure problems, understand charts and undertake mathematically based problems. If reviewing the old cases will help you to do this then absolutely it's a good idea, if not then I personally wouldn't bother, you don't need to learn old cases. 

Good luck!

You should review them after you've done them. If you haven't, yes it is a good idea to review before the interview.

I can't really say what's the best method… the objective is to understand what is a good approach, what are good structures for “brainstorming” questions, and what shortcomings you have and how to avoid them.

Hi there, 

I'd recommend to trigger active recall and instead list out the 20 most important things you've learned from doing these cases. 

This is much better than trying to quickly browse through all the materials.

Hello,

I wouldn't say this is the best use of time. You could review a couple of cases that were tricky, and particularly focus on the areas that you found the most challenging. You could also review some general frameworks, types of exhibits, and calculations. But to get the most out of the process, you should be reviewing cases right after you do them!
