Its been two years, but I'm still waiting to hear back from UVA and Hopkins... among about 8 others. Actually about 20% of the programs I interviewed at gave me nothing in regards to the status of my application or a rejection. Some of the programs that I really wanted to go to, I contacted personally. That was also hit or miss... about 50%.
If i were you, and I were really interested in a program you haven't heard back from yet, call them. Email them. Let them know your interests! Persistence, viewed by some as annoying, can also say a LOT about your interests in a program, and I have known several applicants who managed to get an interview because of persistence. "The squeaky wheel gets the grease." Granted, that's not going ot happen all the time, but there are always cases. And I wouldnt' do it to a program unless you truly were interested. Don't waste a program's time if you're just doing it to beef up your interview #s.
I knew of a guy who had horrible board scores and grades, but kept bugging the PD at conferences and via email and what not. Managed to match at a PGY1-4 program.
