Just had my interview with alum here in NYC. Standard questions posted here and elsewhere. Interviewer clearly had a list of questions to get through, but it was still informal and relaxed, and after we had a chance to chat about business, school, and NYC. Overall I think it went pretty well.
He introduced himself
1. Walk me through your resume
2. Why an MBA, why now, why Columbia?
3. Led a team?
4. Professional or personal challenges?
5. Someone asking you to do something you disagreed with (this was the ethical dilemma question)
6. Is there anything you would do differently in your career or academic life thus far?
7. Anything else about Columbia that attracts you or you want to know?
8. Where else are you applying? Why are you applying to those schools?
9. What if you don't get into any schools, what will you do?
10. Why do you want to do what your long/short term goals are?
Lasted about 30 minutes. Friendly but definitely structured. I got the feeling it is a very small part of the overall application. Hope to hear soon.
