I feel like I'm making this comment over and over on HN, but this is a great approach only when the going is good. But one needs to be flexible and change their mental attitude appropriately when times are not so good. Sometimes you just need a job, and in those cases the interviewer and interviewee role is quite clear.

I might be the only one who actually remembers 2001-4, and trust me, during that time if you walked in with the "I'm actually interviewing YOU!" attitude, you were in for a surprise.
