yeh, i cant tell whether these letters i get are impersonal sent to everyone or what... they are from my interviewer and the hockey coaches saying looking forward to seeing me, but that could just be generic.
yes i believe rejection and waitlisting are generic, but acceptance have a bunch of things of why they picked you. like personal things. they talk about your strengths and weaknesses. waitlisted letters actually sound like rejection at the beginning but the last few sentences say that you have been waitlisted, so who knows.
