I attempted to ask this in another post but... Some PDs/ interviewers have told me that letting them know they are at the top of my list come Feb. is important as that will somehow alter their decision? It has been stressed before that letting a program know they are being ranked highly by the applicant is an important move. How does this work and why do they care? Can't they just go further down the list without that knowledge? It feels that we really have one shot to pick a top program, let them know they are #1 and hope that we get ranked to match. Any insight? Do people tell multiple programs they are #1 in that case to minimize risk of not getting a top pick? Any help is appreciated.
