for those few who curious about interview here's a snippet of email i got from manager:
For all applicants who have not yet interviewed, please note that we take a two-pronged approach to ensure admissions decisions will be ready to be released on January 15, 2011.
• During the weeks of December 6 and 13, the admissions team will travel to a variety of worldwide locations for Global Interview Week (GIW). Invitations for GIW will be sent out within the next two weeks, including locations where interviews will be held.
We prefer face-to-face interviews. Because of this, we travel to cities around the world to conduct interviews in order to make the travel requirement for our applicants less cumbersome than a trip to Washington, D.C. For those applicants living in the Washington, D.C. metro area, and for applicants who would like to participate in Experience Georgetown our campus visit program, we will host on-campus interviews.
• Applicants may be invited to interview at any point during the admissions cycle. Therefore, applicants who have not been invited during GIW, or by the January 15 notification date, may be invited in subsequent rounds.
