hey guys just a word on my own experience applying here last year, with >14000 applicants obviously getting an interview is the biggest hurdle, but after that nearly everyone is either accepted or put on the WL post interview. i like to think of GW as an insecure significant other, meaning that they constantly need to hear reassurance from you about how much you love them, why you think the two of you should be together, what you'll do for each other, etc in the form of letters of interest and intent. sounds silly? well it is absolutely true haha, just ask anyone on the WL this year. if you end up getting on "hold" pre-interview, same rule applies. im unfortunately still on the WL, despite spilling my heart out in letters of interest for the last 6 months.
oh yeah and I got an interview in September last year just a couple of days after submitting my secondary, I am the epitome of an AVERAGE applicant. I'm white. I truly have no idea what this school looks for but if you don't get an interview right away just keep expressing interest!
