In my case, I did my interview with Ms. Cheryl Jones in her admission office on grounds last year. it was very casual and relaxing conversation with normal questions:
* Tell me about yourself starting from college, why you chose your major and continue doing that?
* Any activities back in college? Any leadership role in college?
* What you have been doing after college? Why came to the U.S. for engineering education?
* Anything you feel great during your professional career? What would your co-workers say about you?
* Why MBA and why now? How do you see yourself in next five years after MBA? Long-term goal?
* Why Darden?
* What do you do for fun? any hobbies?
* Any questions about Darden?
As you can feel, it was just a conversational interview which took about 40 minutes. Be aware that the interviewer prefers not seeing your resume until the interview is done, which is a blind interview. So please be prepared to be a smooth story teller and then you will knock the interview down.
