No, I think that by the time you've gotten to the interview stage, the interview becomes the most important thing. (Sorry to disagree with everyone else.) Once you've gotten the interview invite, the admissions committee has already pretty much decided that you have the academic ability to survive their curriculum. Basically, they've established that you've got the "tangibles" that they want. The interview, then is to establish that you've got the intangibles as well - can you have a conversation, are there any red flags in your behavior, etc. I'm sure it varies by school, but the impression that I've always had is that all interviewees are, more or less, on even ground when it comes to academics, ECs, LORs, and MCAT. The only differentiating factor then becomes the interview. Of course, I could be wrong - is there anyone who has worked closely with a med school admissions committee who can put in their input?
