Just wanted add one point to auster's analysis.
Us first years won't have conducted numerous past interviews from which to base comparisons. However, we will have our classmates (good and bad), past pre-med acquaintances, and our general sense of intuition to guide our evaluation of the applicant.
This is by no means meant to scare anyone (because it's not just a rumor that Pitt is an extremely friendly and inviting place), but to point out that, yes, us PittMed 1st years are people after all - we were in you position not too long ago!
Good luck y'all.
