I interviewed at the University of Michigan and was really impressed with the program. Ann Arbor is a small college town, but not too far from Detroit city, so location is important to think about. The dinner the evening before was great and many of the residents brought their significant others with them, which made it more relaxing and more interesting. Overall, I thought the program was strong in all of the major subspecialties. Rumor has it (from a student at the University of Michigan med school) that interviews are granted to the top 100 board scores from their applicants. Don't know if it's true. I'll probably remeber more stuff later.
