First round consisted of 30-minute case interview and 30-minute behaviorals. Case was given during the interview itself. You have 10 minutes to review the case and write down your ideas on the questions asked, and the rest of the time to roleplay with the interviewer. I was supposed to pretend I just received the case from the client and was tasked to explain the case to a senior consultant and provide suggestions on next steps. Completely interviewer-led; but, questions asked were not the same as what was written in the case. Questions written on the case was more about how to solve the client's problem, while interviewer's questions focused on understanding what the actual problem is and why it is relevant. Kind of threw me off because I spent a lot of time answering the questions on the case when he actually asked only one of them.
