First and foremost, congratulations to you all. This is awesome news.
I actually want to just report back. So as my previous replies show, I applied and was waiting an answer, interview or no interview, a few days after all of you got the invite. I kept calling and calling, they said interview decisions would be out at least 1-2 weeks prior to the interview dates. By January 28th, I did not receive any information.
I decided to go to the 'Open House', listed on the site (that Sunday Jan 30th), in the event that I was still an active applicant. I talked with both Marlene, the applicant director and Dean Beck. I was quickly told, "Oh, well, if you didn't get an invite so far, you're rejected". After a bitter few seconds, I generally accepted it (and honestly figured as much before I went). Asking why I wasn't told before, they said... well all letters went out on the 13th. Ok. Three days later, I find the letter in my mailbox - post-marked January 31st. Perhaps I'm still bitter, but I think that's poor form. I'm rejected, ok - but we're adults - we can be honest with each other.
Let this not tarnish your good news, everyone. I just want to provide my perspective. Admittedly, my respect for this fine institution has diminished since I submitted my application. Good luck in your med school decisions everyone.
