Well... My Interview was taken up by Stacey(Director of Admissions).
As far as the Interview goes, it started with the standard questions..(why MBA, why Smeal, what after MBA, why did you choose a particular concentration etc etc). My advise to you is to be prepared for those kind of questions..
There were also some non-standard questions pertaining to..
.. contacts that can help you with a post MBA job..
..Community work that you were involved with etc..
