I remember doing a phone screen with a company who shall remain nameless, but it was a phone company that has a three letter name and two of those letters are the same :-). It went pretty well, and I predictably got not response back from them. A month or so later I accepted another job, moved my family across the country, and started on the new job. About 2 weeks into my new job, Three Letter Company's recruiter calls back and said the phone screen went great! Can I come in for a round of in-person interviews?

I LOLed over the phone, it was a riot.

EDIT: On the other extreme hand, it's a HUGE turn-off when a recruiter makes an incorrect assumption about my time availability in the initial contact. Stop me when you've seen this one: "Your background looks great! Please tell me what time slots today would work for you in order to discuss this role." Wow, really? You're assuming I have time to call you RIGHT NOW?
