Not really. It happens.
The only time I get angry is when I truly feel I've been lied to. Someone applies to my IM program, and their application looks like they are applying to Rads (lots of rads research, experiences etc). They tell me in their PS and at their interview that they've totally changed their mind, and now they are applying to IM instead. Then they match in Rads. Sure, maybe they had a "change of heart" again, but really we all know they applied as a backup. Mostly, I'm angry that someone else didn't get a chance to interview with us because they filled a spot. But it's all water under the bridge.
