Simon Interview Expereince!

Well guys, I had my SIMON interview today at around midnight my time. The interviewer was an Alumni, she was from 2007 batch(Part Time). The interview was more kind of conversational than anything else. The questions were also standard and some of them were as follows :

Walk me through your resume?
Why MBA?
Why do you think this is the right time for you to complete your MBA?
What do you expect from the SIMON school of business?
How can SIMON help you to achieve your goals?(I failed to understand what was the difference between this question and the previous one, comments/suggestions welcome.)
What unique qualities will you be bringing to SIMON?
Tell me about a strength and a weakness in your application?
How do you handle conflicts in your team provide an example from your professional life?
Any Questions I had for her?
I asked her few questions but as she had completed a Part Time MBA she was not able to provide good explanations for the questions I asked which were mostly related to full time program.

This interview of mine made me wonder, as on what factors do the AD-COM decide that a particular candidates needs to be interviewed by the AD-COM or by an Alumni. I feel its not a random selection, What do you guys think?

Till the time me meet again Guten Tag Zusammen :).
