I got my invite a few hours ago as well (applied late evening on 10/14).
I did get that invite to the women's day in February, but I don't think I'm going to wait for it. I'm early action at Tuck, and I'd like to make sure I know all of my options in December-- not wait until February. I'm flying from the west coast. It's not fun, but international would be a lot worse...
FYI-- the interview slots are booking FAST. They clearly have either been doing rolling invites (which I think we would have heard about), or they are only opening interview slots in batches. When I checked when I first got my email, there were multiple options each day. I just checked now, and there is only one option for the day I want.
