They might like big numbers, but I think the only reason I got in was because I am a good fit for the program. It took me 3 attempts to get a MCAT score towards low end of their 25-75% range, and I did not submit my secondary until October due to a late last minute hail mary MCAT attempt, but I still got in (and no I did not go to Case for undergrad and I am not a URM). I guess to be fair, my gpa is very high, but I don't know how much that really counts.
In my interview I talked about my research for 10 minutes, family for five minutes, my learning style for another couple of minutes and we spent the next 25-30 minutes talking about the Cavs and Browns. My interviewer was a Steelers fan and we had a pretty heated discussion, though civil. It was fun. 😉
The most important thing for Case is fit, followed by personality. If you got to the interview stage, it's about something more than numbers. I'm just happy to have gotten to that stage, because no other school gave me the light of day.
Good luck.
