Also, in this round, I was informed as to which industry focus I was being considered with, so the consultant asked me relevant questions to that end. 3. In-person interviews. Three parts. A. Behavioral with Manger. It was standard fare. He gave me mini situations to assess and rated me based on some trait they were looking for. B. Situational. This is actually a standard case interview with a Principal that you would have at any of the other big consulting houses. C. Case. You get a business case 48 hours in advance, you review it, then you arrive the morning of, get a page-long case question, and prepare a 3-7 slide presentation in an hour, which you then actually present to a Principal.
