Few questions about post-interview communication. I know that this is something that may have little impact, but nonetheless.
(1) Do fellowships have the same rank list certification deadline as applicants?
(2) Is there a "latest" date I should send a "you are my #1 e-mail"? I have several weeks more before my last interview, so don't want to jump the gun, but several PDs have said to reach out later if I am "seriously considering [their] program," which makes me think that if they are my #1 I do really need to tell them.
(3) Are people sending e-mails to programs 2-3? I have a shortlist of programs that I would love to go to, and I'm not so confident that I'll match at my #1. I want program 2 and 3 to know that I am very strongly interested, but I worry that sending an e-mail without specifically saying "#1" may cause more harm than good...
it won’t cause more harm than good because a “#1 email” is not an official thing that is part of the process. People have matched #1 without sending an email and if you look at the data, only about 30% of people match at their #1 anyway so the majority of people match somewhere who they did NOT send a #1 email to.
