The last place I applied, my soon-to-be supervisor showed up in flip-flops (like, the $2 rubber wal-mart kind) and they brought the wrong resume to the interview. My now VP looks down at the paper, looks at me, says "You're not Craig?"

Then they sat on the fence about hiring me for, oh, 6 weeks or so.

All is well now, but that was the oddest interview I've ever done.
