I applied at FedEx last year and they actually called me but I just barely missed it so they left a voicemail with 2 people's names in case the other wasn't there so I call back within the hour and the person who answered said that they were both out but that she'd let them know and they'd call me back in half an hour. Didn't happen, I figured it wouldn't have been a good job anyway, their hours suck and I wasn't going to go chasing down someone just to beg for an interview.
Fast forward to today, they call again, asking if I'd like to come in for an interview. They're desperate for me but I'm not desperate for them. They're at my convenience, not the other way around. They wouldn't finally call back months later otherwise, probably going down a list of applicants, wouldn't even be surprised if they called people they previously rejected.
