I received my admit call around 11:06 am EST. Interview invite went out on the 14th and interviewed over Skype on the 16th. I am in Arizona and my last name is very near the end of the alphabet, so I wouldn't put much credence into the idea that the calls are going out on the basis of names. If I've learned anything from this process it's not to read into things too much. Georgetown was my first application, and It was virtually silent from them for three months before my interview invite.
I'm hoping for some sort of scholarship now, but good luck to everybody else!
