Now that I have finished interviewing, I have picked a #1 program and want to have my PD make a phone call for me to that program (and just that program). I have been told that phone calls do often affect your position on the rank list. However, I have frequently heard of programs making their rank lists immediately after they finish interviewing (same day). Does anyone have any idea as to when it is "too late" to have my PD make this phone call?
