I don't get people who run interviews with no sense of humor, at least a smile or two.  I had a phone interview a few weeks ago with a well known internet company, the interviewer started the interview with "do you even know how to code?"  That interview ended pretty abruptly.  I didn't hang up, but got out as fast as I could. I don't care how well known the company is, that isn't an environment I have any interest in working in.
