So there's really no indication of age discrimination as far as I can tell even at the very top schools as long as your application is strong.
And there are several late 30s/early 40s people in my class right now.
Interesting discussion. I'm in my mid-30s and applied this cycle. In my experience age was definitely an issue that I was asked about frequently at my interviews (
i.e., every interview I went on). Typically, the questions involved "Why has it taken you until your mid 30s to decide that a career in medicine was for you?" I feel that these questions were warranted as far as trying to assess my motivations for pursuing a career in medicine, even though by some accounts certain age-related questions are not "supposed" to be asked [see, for example, Avery Jr. DM et al., Am. J. Clin. Med. 2010(7), 94-95.]
That being said, at more than one interview I think the interviewers crossed the line between legitimate questions about my thought processes and outright hostility and/or inappropriateness. At one interview I was chatting with the interviewer in the few minutes that remained in our time after she stated that I had answered the questions to her satisfaction. I was asked what I thought about the interview process and said that it was a great opportunity to see schools and get a sense for the atmosphere of each place, but also that the waiting to hear from schools was challenging at times. She replied that "If you were maybe 6 years younger, you probably would have been interviewed earlier in the season and maybe even admitted already." I sure hope I kept my poker face on, because inwardly my jaw dropped at such a candid admission on her part.
What shocked me the most was not the fact that the interviewer said this to me (if anything, I appreciated the honesty), but rather that these were factors that were used to evaluate my application. To be fair, this was only the comment of one person, and I don't know whether this interviewer was just a loose cannon, or whether this particular comment did, in fact, reflect the ethos of the adcom.
This was certainly the most egregious case of these sorts of questions, but I had interviewers at other schools who strongly implied that same sentiment of age being a negative at their institution. Needless to say, this experience made it very difficult for me not to believe some of the worst things I've occasionally thought about the application process: that it is in many ways arbitrary, utilizes factors irrelevant to aptitude for medicine, etc.
I suppose one just has to chalk it up to the black box-ness (pardon the neologism) of this whole process. I obviously can't say for sure, and will never know, how much or how little my age had to do with how my application was evaluated. Somewhat frustrating, but the criteria that adcoms use to evaluate applicants is something over which I have no control, and on which I have no influence.
Just my $0.02 worth, if that, even.
