Yeah, it didn't work that way for us lol. If by cohort, you mean EMDP2, only half of my cohort was even accepted, and a lot of us sat on the waitlist or the alternate list for a while first. We had folks with 510+ MCATs, years of SF medic and ranger experience, fun stuff like working at a record label, linguists, etc. get waitlisted, put on the hold or alternate list, or rejected.
I had extremely laid back and awesome interviews (a Navy ophthalmologist who took a look at me in uniform and said well, interview is over let's just chat and hang out, and a retired AF col whose daughter was a writer and a musician just like me, and we talked almost exclusively about my music and writing--both gave me 5/5 lol). The explanation came after my interviews for the committee.
I'm an MS2, so this doesn't even apply to me. Just offering advice based on my own experience. I had what I thought was a pretty mild deficiency (3 Fs from 14 years ago followed by years of As and Bs with a 3.6 in my math degree, a 4.0 postbacc, and a 519 MCAT), so I never brought it up in the interviews. I was then blindsided with a request for an explanation via email that I had a very short time to respond to, and I was waitlisted because of those grades.
It would have taken me like 2 minutes of the 45 minute interview to mention that, and maybe if I had and my interviewers had also written about it in my favor, I wouldn't have sat on the waitlist. I did that at the next school I interviewed at even though I wasn't asked, and I got in like two weeks later. Anecdotal, but none of this is data driven. Just giving my opinion based on my experience (that to be fair is more recent than yours). Anyone can take it or leave it. But if it helps someone, then I'll be happy.
EDIT: Oh, and my info also comes from a couple years of talking with Col. Saguil and CAPT Liotta as well. They were very present and open with us during EMDP2. I miss Col Saguil and was looking forward to saying hi to him next year at SAMMC, but COVID ruined that.
