hey, guys, i just realized that i'm no longer getting notification of activity on this thread. Goofy.
So these responses are probably outdated, but....
Application FeedbackDuke doesn't give feedback unless you went to one of the special weekends, such as W4W or the Workshop. I asked them this same question last year, and it's because they found that so few people re-applied.
Interview / Essay ConsistencyDon't worry about changing your essays from your interviews - the interviewers don't take copious notes on exactly what you say. It's more about who you are. Large themes ("wants to do ibanking") may be noted, but no one will notice something like "wants to help classmates understand small business in developing nations" versus "wants to use her math skills to help classmates with non-quant backgrounds." Those are not mutually exclusive anyway.
Post Matriculation SurveyI think I recall getting a survey about my time between admission and starting school. I think it was more about finding out how much money i was making or something. seriously, you are in and can do just about anything at this point. (Well, they'd ding you maybe if you got sent to jail for that coke binge.)
Good luck to everyone in R2! Let me know when you come to visit - i like to G'Clubbers if I can.
