Most people know NYU for its name. After interviewing, I think NYU is very over-rated. Columbia, Cornell, and Mt. Sinai are all so much better than NYU. It was quite telling when a student leading our tour mentioned "here is our dorm...here is our gym...here is our anatomy lab" and the interviewees just looked at each other with a dumbfounded look saying, "No way, this can't be NYU." But it is. You will see for yourself when you interview there. I don't know how anyone would choose this school over any other school in NYC or for that matter, anywhere in the US.
NYU, for the most part, is a dump. Facilities are terrible.
Administration seems a bit harsh. Med student dorm is worse than living in the gutter. The disparate nature of student groups -- there are just way too many.
What did you wish you had known ahead of time?
How dilapited NYU is...I wouldn't have bothered interviewing there.
