Now that I've started posting messages, I just can't stop!
I started my interviews in late October (where I was doing an away) through the end of January. It's true, you get pretty tired, and I had scheduled my Harvard interviews at the end, thinking those were my top choices and I wanted them to remember me. However, by mid January I had enough, and I cancelled the Harvard hospitals just out of exhaustion. Now, I dunno how the order of my interviews affected the programs' ranking of me, but I do know that it affected my rankings. The last program I interviewed at stuck out the most and ended up being my first choice.
