I looked at this site, read my AMCAS and secondary application, and talked to a friend to get possible questions that may be asked.
What impressed you positively?
Everyone is really nice, from the administrators to the students.
What impressed you negatively?
The lunch that was provided was small, I suggest you eat a good breakfast in the morning because you will be waiting some time to be called up for your interview.
What did you wish you had known ahead of time?
Once again the size of the lunch.
What are your general comments?
This was my first interview so I was nervous. I read this forum before my interview and it made me nervous because of the way the interview was described. It is true that the 2 faculty that are interviewing you will show no expression to your responses during the structured portion of the interview. However, they do smile and nod (they are not completely without emotion.) After the structured part it became more of a conversation. So you should relax, there is nothing to worry about. The most stressful thing for me was just waiting for my turn. Once I was called the stress level went from a 7 to a 1 during the interview.
