It turns out that one of the residents at a program on the east coast where I did an away rotation I knew in a past life, and we did NOT get along personally. We didn't work together, but we did civilly run into each other and now I am worried that this person will advocate against my application since he knows I am applying to their program. The rotation went very well, and I really want to go to this school and am very willing to work professionally with this person. I have a strong application with solid LORs, and my professionalism and teamwork were repeatedly commented on throughout my third-year rotations.
I am worried this person may try to advocate against me if I apply to this program, which is one of my top choices. This may be paranoid, but I'm also worried that if this person does speak to the PD about me, the PD will share this with sister programs. Does this ever happen?? Thoughts?
