i was verified in october or november and mailed in an amcas ap to them in november.
i interviewed dec 13-14 (md/phd)
i don't know how many notches penn is down from the top of the ladder, admissions or otherwise. i think of it as right up there with duke and ucsf and hopkins (i somehow see harvard as standing alone in its unattainable status, but maybe that's silly). i think that most would say that penn is a top 5 school. some people don't like philadelphia all that much but compared to baltimore . . . =D
chances are you WILL probably get an interview, (it sounds like you deserve one!!) but i have to say that this whole thing is such a crap shoot that it's hard to count on any one place. i have stats virtually identical to yours, and while i have gotten lots of interviews, there are places i was outright rejected without interview (washu, cornell, yale, all for md/phd, but still) and places i haven't heard from yet (emory, ucsf, harvard).
good luck! maybe we'll be penn classmates some day (it's one of my top choices too!)
