I've seen other people post this same complaint about various other med schools (go read the Wash U thread, for example), and I really don't get it. If you feel that Case is so horrible, why would YOU waste YOUR "valuable life" applying there in the first place? Or accepting their invitation to interview? You do know that you can decline the interview, right? You don't have to go just because they invited you! Or are you saying that you thought they were great until you got to the interview, and now you think they are "disorganized and inconsiderate" because there's only a 1/3 chance that they'll take you?
I'm not trying to put you down; I truly don't understand what you're so upset about. EVERY school interviews tons more people than they accept, and waitlists many of them. There are several schools that interview on the order of 1000 people (and BTW, are you sure that those are all for the UP, or does that include CC too? Because if it's the latter, then you'll have some people who interviewed twice, once for each program, which would seriously skew the stats.) I just don't see what's so different (or horrible) about Case's interview process compared to any other school.
