Hi Markus,

I would be happy to share my thoughts on it:

• First of all, in my opinion, not all of the "additional information" listed in the case study needs to be inquired about from the candidate. Therefore, I would highly advise you to suggest to your peer to strike a better balance between providing information proactively and waiting for the candidate to ask for it.
• Furthermore, while the case study may seem a bit lengthy, it appears to be quite standard (to the extent that there is a standard).
• Lastly, I would highly advise you not to overestimate the difference between interviewer-led and interviewee-led case studies, since the only difference is that after you make a proposal (e.g., for the initial structure or for a solution to a quantitative question), you will give the interviewer time to react to your proposal, which they will either follow or not. I have seen this misconception way too often, that you would not need to show case leadership with interviewer-led case studies.

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
