Oh, I know programs send goodies bags. They send them to everyone though on the off chance that the most highly desirable candidate is swoon over by the gesture. It never (or maybe extremely rarely) happens though.
During the discussion of rank lists… none of that fluff stuff is relevant though. It’s all about scores, publications, LORs and the ability to articulate a career plan. No one ever brings up “but this person sent a letter to me expressing interest” as a way to tip the scales. At least not in my 10 years.
As an aside, the fact that communication happens through program social media is just sad… but I realize I am of a different era where that wasn’t even a thing.
Either way, that’s all beside the point. My point is if you send a LOI don’t be surprised if 1) they ghost you or 2) it’s impact is negligible. But I get it, in the lottery system, you don’t win by not playing…
