Effective Interview for MBA Programs

Since I volunteer to interview MBA applicants for my alma mater, I have interviewed more than 30 persons so far. In these interviews, I have observed several key elements for an effective interview. If an applicant shows these key elements in the interview, it would be easy for me to write a favorable critique form for the applicant. The point is if an applicant can convince me, then it's easy for me to convince the admission committee. Belows are the key points I am looking for in an interview.

1. Differentiate yourself - Why are you different from other MBA applicants?
   
2. Be specific - When talk about yourself, please give examples to support your statements.
3. Think of Win-Win - Why do you think the admission should give you, in stead of other applicants, the admission?
