Hello,
I have interviewed at Case and I really liked the school! The interview day is really laid back, so don't worry about it. You interview with one faculty member, and the interview is supposed to last about 1/2 to 1 hour. I didn't personally get asked any real challenging questions...the interviewer just seemed really interested in learning more about what I had written down in my application and giving me information on the school. You also have a tour of the school, a talk with current students, a talk from financial aid people, and lunch.
I really liked the atmosphere and the attitude of the school...come prepared with questions because there is tons of time to ask them. Good luck!
🙂
