Re: Brown interviews, I asked just about the same question a few days ago. Ha. It definitely seems to be around that time.
@Bschaefer says that he and a friend had interviews a long time ago (i.e. 1+ month ago)-- I'm confused about that but am also not sure that those were the "official" formal interviews, if that makes sense? I met with a professor for what I would consider an "informal" interview at Yale, for example, in December.
