1. Wing it
2. Don't sleep the night before
3. Quote a lot of shakespeare to sound intelligent
4. When the interviewer asks you a question, ask them a question instead
5. Make sure you have a horrible internet connection for remote interviews
6. Just memorize frameworks and throw them out left right and centre, regardless of the case prompt
7. Appear very very unenthused and disinterested
8. Don't smile :)

You don't have to prepare at all :-P just come as you are. But if you want to prepare, read Case in Point; reading it should be more than enough!

Hi,

I will go for a 4 step approach

• Step 1 | Work on frameworks in books (e.g. case in point); amass content and build your tool box. Attention, the day of the interview in most cases you should not make a mapping between the frameworks you studied and the case stated by the interviewer. You often have to build a customized framework.

• Step 2 | Train with peers. In a case study we test the structure of course, but also the business sense and the ability to use the indices or the data communicated by the interviewer. It is not a 1-way talk but a real discussion between two people. Here is the real limit of training using books.

• Step 3 | Test yourself with people who have really been interviewer in consulting firms to benefit from cases that have been tested for real and feedback through the evaluation grids of consulting firms. Of course, I would be delighted to discuss it with you when will be in this phase of your preparation.

• Step 4 | Multiply the applications and therefore the real interviews. Nothing prepares better than a case study in a real situation. Morever, the more applications you submit, the more you maximize your chances of having one or more offers. I recommend on the other hand, to start with the firms that you target less and to keep top priorities for later.

I finish by reminding that it's compulsory not to neglect the fit which is often less prepared than the case study. So please do not forget that this part of the interview counts as much as the case study, so it is very important not to improvise.

Hope it helps.
