I was wondering whether anyone knows how likely departments are to provide feedback (general, not exactly nitty-gritty) on a denied application? I was under the impression and heard through others over the years that it is not unusual for a denied student to contact the department and get an idea about why their application was not as competitive. I've reached out to a few places at the moment and only got one response (that they don't do that because of the amount of applicants they get). In my communications I always note that I am planning to re-apply (which is something I am actually toying with at the moment) and would like some general feedback but have not heard much back. Am I wrong in thinking that this is a fairly reasonable request? It seems to me that this is something that departments do (with limited info about fit or unacceptable GRE etc). I would really appreciate any info/feedback from the community. Thanks
