Huh I remember 2 interviews that I was sure I am never ever going to work at the company :-) At one well-known-company interviewer literally treated me like garbage from the very first minute (including waiting for the scheduled meeting in the building corridor), I didn't even try to do say anything then. Another one started pretty well, but then I saw the team (super demotivated) and they asked me to do some shady test-stuff (HTTP referer header spoofing), but the nail to the coffin was the manager telling me that I have to disregard notice time and instantly jump ships for them, because they won't wait for me ;-) So yeah, the interview works both ways, there were jobs (like my current one) that I felt that the fit is strong and the final negotiation effects are not so important.
