I interviewed at TC campus last week and can give a quick summary of the day. First of all, my interview group was very small which was nice because it made everything more personal. There were two interviews, one with a faculty member in the morning and another with a med student in the afternoon. The faculty member interview is open file save the stats. Mine had questions prepared beforehand and tailored to my app and essays. So, make sure to know your AMCAS and essays well. It was very laid back and enjoyable overall. The length of my interview approached one hour. Don't know if that is normal or not. I didn't get any ethical questions but one of the other interviewees said that they did.
The second interview with the med student has no bearing on your admission. The student told me that at the beginning of the interview. So, I don't know what the purpose of the med student interview is other than for you as an applicant to ask any further questions you might have about the school. Because the interview had no admissions implications it was once again very relaxing. This interview was shorter and closer to 30 minutes in length.
Overall, the entire day was enjoyable and I was very impressed by the U. All the students that I met seemed friendly and happy to be there which was a positive sign.
