SUC as well today (#3, interviewed mid-October). I ran into someone from my same interview day this fall who told me she was rejected, so they indeed are sending out post-interview rejections.
As future scientists, keep in mind that SDN is a VERY biased source of information, those getting interviews/SUCs/acceptances are much likely to be more engaged with threads than those who are rejected and have moved on from a school. Personally, I've been posting in places I have heard good news and haven't posted about any of my rejections to other schools' threads. Thus, there are likely many more rejections than we are seeing on this thread.
Good luck everyone! At this point I'm banking on no real news til March. Could be worth the wait, maybe it won't be. Would gladly take even a lowish waitlist spot.
