Read interview feedback, read about Wash U on their webpage, talked to students.
What impressed you positively?
The facilities are amazing, especially the children's hospital. The students, including the prospective students that I interviewed with, were very nice and outgoing. My interviewer was unassuming and seemed genuinely interested in me and my interests, even though he is quite distinguished as a doctor and a scientist.
What impressed you negatively?
The Dean of Admissions. He was supposed to give us a welcome and an orientation to financial aid, but he spent the whole time telling us how selective Wash U. is and how they pick their class. He and others gave me the impression that Wash U. cares more about the MCAT than anything else and they try really hard to get students with high MCAT scores, to the detriment of other qualifications. I heard several students say, "Well, I never volunteered in a hospital before I came here." or "I never did research before I came here." or "I was kind of a slacker in undergrad."
What did you wish you had known ahead of time?
St. Louis has a great public transportation system for a city of its size, especially in the midwest. It also helps that Wash U. has its own shuttle system that serves the main campus, the medical campus and several of the surrounding neighborhoods, and anyone can ride it for free.
What are your general comments?
It was a really fun day. Overall I had a good impression of the school and I think I would be comfortable there.
