I just called the UPenn Perelman office to ask about application updates and they said that their last interview date is next week, and basically if we haven't heard anything yet, we will get "final confirmation" sometime next week (aka rejection). The lady I talked to was super nice though
.
I also called the University of Maryland MSTP office and the lady I talked to was also very very nice and she said that they are still definitely giving out interview invites...although they also said my app has not been reviewed yet and I was complete beginning of September...
Still some hope! And I haven't gotten any "on hold" emails either.
I called University of Virginia and no one picked up, and Wisconsin-Madison has no more interview spots available. There are 2 people on the interview waiting list who they'll invite if anyone cancels, and after the waiting list there is a hold list.
Hope this helps! Good luck to everyone!!!
