"I applied to Yale SOM in RD1 this year and didnt hear anything from them until the decision date(17 Dec 2009). On the decision date (or I think a day prior) I received an interview invite. I interviewed in late December and got my admit call in January(almost 3 weeks after the official decision date). So the moral of the story is..dont lose hope guys! When schools say they extend interview invitations until the decision date , they really mean it!....so keep refreshing those mailboxes!!! who knows u might just get one! ;-) "
