First of all, relax! I interviewed there back in September and the day is very laid back. If you interview in the morning you'll meet with the director of admissions for roughly 45 minutes and she'll go over all the general information. You'll then be sent off to find your interviewer (she'll give you detailed directions). My interview lasted about 40 minutes. It is closed file so he knew nothing about me and didn't want to know my GPA/MCAT scores. The community physician who I interviewed with also asked that I not tell him my numbers, so I think they are truly interested in getting to know the person behind the application. The faculty interview was very conversational and basically we just talked about my experiences and why I want to go into medicine. You may want to brush up on the issues of illegal immigrants from Mexico using the University for health care and the lack of trauma services in Tucson, we did talk about those issues but I brought them up. I would just suggest that you relax, be yourself and enjoy the interview. They really aren't out to get you. PM me if you have any more questions.
