It seems that MBB firms could give both type of cases - candidate led and interviewer led. I usually structure the question by a candidate led style. But among the cases I've practised with people on prep lounge, I find that sometimes it is hard to define which kind of case type is it. In some interviewer led cases, the interviewer does not ask me questions directly like interviewer led style cases. I rather feel that it is a candidate led case. So when the interviewer starts to ask me questions after I have completed some part of my analysis, I start to panic since I feel that I must have missed some important parts so the interviewer is asking questions to give me "hints" to proceed the case.
My question is:
1. In real interview scenario, is it easy to spot whether the case is candidate led or interviewer led (several seperate and individual questions) style? In interviewer led case, will they directly state the questions one by one, instead of randomly throwing out some questions in the middle of the case?
2. Any advice on improving my struggling situation mentioned above? How to have a steady performance and natural flow when the interviewer starts to ask you questions that is not covered in the initial structure? Should I ask for some time to "update" my structure?
Appreciate the advice!
