In the MD/PhD interview, the panel seemed very interested in my past. For example, they asked me what I learned from my experience of living in a car during high school.
Read the MD/PhD website and my application. Thoroughly reviewed my research.
What impressed you positively?
Many things. They have a brand new shock trauma center and a beautiful atrium in the hospital. "Smart rooms" facilitate med-student studying and exam taking. Program administrators and interviewers were all extremely helpful and friendly.
What impressed you negatively?
Not much. The school is very research intensive, but they aren't as heavy on clinical skill training as I would like.
What did you wish you had known ahead of time?
Some research departments are strong, others seem to be not so strong. It would have been nice to know which before the interview.
What are your general comments?
Highly positive experience. The first hour is spent with the program director and his power point presentation.
There is an MD only interview after this, but it's only important if you are not given a position in the MD/PhD program. There are three to five informal meetings with faculty in your areas of interest and the day ends with a half-hour panel interview.
