Hey there Eternal,
My interview lasted about 35 mins and was prety straightforward. The questions I was asked were ones I had prepared for and didnt really make me break a sweat. They were
1) Summarize your full time work experience to date
2) Why MBA? Why now?
3) What are your short term and long term goals?
4) What aspects of the MS.MBA prog appeal to you?
5) Can you give me an example of when you played a leadership role?
6) Can you give me an example of when you played a role in a team?
7) What lessons did you learn from the teamwork experience? positive/negative aspects?

How do you plan to be active on campus
9) Do you have any questions for us?
One thing that works for me during interviews is interjecting questions of your own while answering the questions the person is asking you. Try to make the interviewer talk as much as possible. Ask questions about him/her, what their educational background is, how long they have worked at X school of management, what they think about the school and the city in general.
hope this helps and all the best
peace
