I think someone asked my submit date a while back -- sorry for late response.
Submitted mid November, got interview invite early December, interviewed between Xmas and New Years (VERY casual -- I wore jeans, as did my interviewer -- I know this is against all the "rules" you've probably read in books, but sometimes you have to know what the occasion is... and in this case it was very appropriate), and my app went Complete today.
So hopefully I will hear some good news soon.
Im not active on these boards at all... but based on all the stress/anxiety I see I hope that everyone takes a step back from the process and is able to think about all that they've gained -- better perspective on career goals, a more polished resume, and a bit more motivation to do something with themselves (even if it's just landing a big gig somewhere).
In any event, chill out, stop speculating, submit/interview/etc. and let the adcom do the rest -- it's out of our control.
Cheers!
