I interviewed at Pomona on 9/7 and I friggen LOVED everything about the school - the students, staff, curriculum, facilities, extensive rotational connections throughout CA. Not to mention, so-cal is the place to be. Haha. The only thing that felt a little meh was the individual interview. But that was just a personality thing. I didn't have anything in common with my interviewers, so it didn't turn into a conversation like most of my interviews do. But they were nice enough.
The questions they asked in the individual interview were actually really cool questions that were aimed at trying to get to the root of who you are, why you would fit their school, and evaluate your level of maturity - e.g. can you discuss your failures honestly without making excuses, can you discuss your weaknesses without freaking out about them, can you think about the bigger picture, etc.
As far as the MMIs go, they were really enjoyable. We can't discuss the actual questions, but just know they are REALLY great actors. Haha. My best advice is to be yourself and just have fun with them!
