I interviewed at stanford last week and was extremely impressed. All the residents were normal (which can never be underestimated) and happy. Each resident was someone I could having a beer with. In addition it seemed like a very resident-friendly program with a very nice and personable chair. I'm not sure how much operating interns do, but the rumors are that they don't do much. Over all I was very impressed with the program and think it'll be a very tolerable, if not enjoyable prelim year.
