Everything! U Penn is a great school. Students are REALLY happy there. I stayed at a medical fraternity house and the people there were awesome... they gave me all these tricks to ace my interviews, but it turned out that my interviews were so relaxing and conversational. NO HARD QUESTIONS at all.

U Penn is the best!
What are your general comments?
It seems to me that the interviews were more for students to get to know Penn than for Penn to get to know us. I don't know if this is a good thing or a bad thing. In both interviews I had, the interviewers spent more than half the time talking about how much they love Penn. My faculty interviewer was particularly friendly. He told me about places to go in Philly (i'm from Cali) and where to eat. He even drew me a map of how to get to all the famous Philly cheese steak places! How cool is that!
