Had my interview yesterday. The whole process (of scheduling my interview and the interview questions) was consistent with what others have reported.
A brief highlight:
I looked up the names of the three alumni (on google) that the interviewer search returned, and selected one based on my preference.
I contacted him, and he responded within minutes. We agreed on time and scheduled that we have the interview over dinner.
My interview questions:
Tell me about yourself and walk me through your resume.(I used this opportunity to tell him a story on my background up to present).
Why an MBA and why CBS?
Why spend two years on MBA?
Why not part-time MBA at a local college?
Tell me about an ethical dilemma that you have experienced or witnessed?
What other schools have you have applied to?
What is your plan in case you don't get into any of the schools that you have applied to?
How does location factor into your decision in choosing the schools that you applied to?
Then he allowed me to ask all the questions that I had for him.
Overall, the interview was conversational and smooth. Though I only got through a third of my dinner since i did most of the talking while he went through his appetizer and main course

FYI - i submitted for RD in mid Nov, got interview invite 6th of Jan.
