I just got my acceptance letter from Case today, so I have a very high opinion on it right now!
As far as out of state interviews, when i was there they said the people they interview is roughly 45% in state, 55% out of state, while they try to get their class to be 60% in-state, 40% out-of-state. The original applicant pool has many more out-of-staters (like 80%), so they try to cut some of the out-of-staters at each step. There are also real quick about the decision process--I was just there two weeks ago! That is very nice! What a Christmas present!
