I interviewed at GW in early September, 9/20 to be exact. I called the office the day after 9/11 to see if I could reschedule my interview b/c I was unsure if I would be able to navigate around the city. Darrell, the interview coodinator, told me that it was in my best interest, even with the circumstances, to attend my interview since they were rolling admissions and generally filled their class by early January. On my interview day, the Dean told me that GW was on schedule even with the AMCAS debacle and the mail trouble in DC because most of their applicants had sent in their AMCAS with the secondary.
They have a lot of waitlist movement. I was put on "alternate" status and received an acceptance before Christmas.
