My faculty interview was short...about 15 minutes. Talking with the other people who interviewed with the same person at the hospital, this was the case for all of us. Those whose interview was at the med school and not the hospital seemed to have longer interviews though, so I think it just depends on the availability of your interviewer. My student interview was longer...probably around 45 minutes. I got an email with directions to the school, parking info, time frame, and local hotels on the same day that I scheduled the interview.
