I heard Pritzker loves teaching experience and puts out a higher proportion of teaching MDs than any other school. Did you have any TA or tutoring experiences?
It's more likely, though, that some medical student was having a bad day, gave your app a negative review and you got screwed. I personally don't like the fact that medical students review applications. What if a student who had a low MCAT score was reviewing? Of course, they are going to feel for the applicants in the same situation and throw out more interviews to the low MCAT applicants than an impartial reveiwer would. The same goes for a student with a high MCAT or trouble with orgo... I don't know, I think the process has many weaknesses, but it's what we got.
Sorry about that rejection
