So I sent my number one program a typed one-page letter telling them why I wanted to go there and that I was ranking them number one. This was 2 weeks ago. I've heard nothing. I e-mailed the secretary and asked her if she could just see if the PD received my letter. Still nothing. From them I received a mass "You've made a positive impression..." e-mail after the interview, but this was before I sent the letter. What do you think? Have I ruined something or are they just bad responders?
