I applied to NYU neural science. I received the interview invitation just before Christmas, and they offered interview dates of Feb. 5-6 or 26-27. I think the timeline is a bit later for international students, but otherwise I'm not sure.
I interviewed at Northwestern during their first session (1/15-1/16) and haven't heard anything. I think they admit their "top picks" the week after each interview session, and will save making a decision about the rest until they have finished all the interviews (last session is this weekend).
OK, thanks. I actually did ask the coordinator about a month ago and she told me invitations would be sent about 2 weeks before the Feb. 27th interview date for SINS, but that seems awfully late.
Good luck to you~
