The students - they were really helpful and laid back and sounded excited about the school. Even people who had nothing to with the interview process (e.g., other physicians and staff) would stop me and ask if I was interviewing, give me advice, and wish me good luck.
What impressed you negatively?
The amount of time I spent at the school. Most of us had one interview in the morning and another one 4 or 5 hours later. They tried to keep us occupied with tours, however.
What did you wish you had known ahead of time?
Bring another comfortable pair of shoes - some girls were walking around with suits and tennis shoes while we were touring and no one cared because it's only the students who give the tour and they're really relaxed.
