Hi there,
It's my first post at PL, really excited to get thoughts from such a helpful society.
Recently after I had several mock cases with partners where the cases are real interiew cases at BCG China rather than those on casebooks, I am confused about raising open questions:
1. I understand the function of open questions is narrowing down the case scope into 1-2 major areas. After hearing the case background, how many open questions (or how many minutes )should I ask before I start drawing my structure?
2. What kind of open questions are deemed to be really "sharp" and helpful? Does the answer to this question change by the case topic (Profitability, M&A, Market Entry, etc.)?
Cheers,
Jerry Zhang
