My interview was an alum who graduated in 2002 and he has been interviewing candidates for a long time. I was nervous going in to the interview, but it was very casual conversation. I was only asked standard questions.
Questions I was asked:
1. Tell me about yourself.
2. Why MBA? Why now?
3. Why CBS and why NYC?
This took 12 mins and we spent the next 18 mins talking about him and his advice to me. I had scheduled the call for 45 mins and was surprised how soon we were done.
No behavioral questions or any curveballs. I was very surprised because I had prepared for behavioral questions, etc. It was conversational throughout so focus on connecting with your interviewer. He submitted the feedback immediately after the interview.
I got in on the 17th day after feedback submission!
