My favorite is the girl (!) who called me for the phone interview - that's a little out of protocol, usually I'm supposed to call the interviewee, but no matter.
Anyhoo, she started the conversation with "Yeah, I'm calling about the &%&#ing interview?" and went downhill from there. :-)
We hired a chinese kid who only lasted 1 day. His mother called and told us that the work we gave him to do was below him.
