My interviewer told me that they meet every Wednesday and they re-read your personal statement, recommendation letters, look at your interviewer's assessment etc. They then take a vote on if the student should be accepted. Those people on the fence, which I am guessing is us, are probably continuously put back in the pile for next week because they may be more sure of us than a spring hold but not enough to be accepted. It may be my false logic though. I doubt people who get rejected are still on this forum, but for those who are, did you receive your rejection within 4-6 weeks of interviewing, or did it take longer.
