I've had a few bad bosses and they never gave me any warning signs in the job interview. In fact, quite the opposite. there was the guy who in the job interview, when he saw on my resume that I knew C programming on VMS, asked me about it. He commented that he could never figure out how to do the file I/O, and I responded (truthfully) that I could do that. It sounded like something he was interested in and wanted for some project. But several months into the job, I couldn't get him to show any interest in my C programming skills (it was a Cobol shop). I assumed he was just too busy, so I wrote a quick demo program and told him where he could find it so that he could check it out at his leisure. He never did. In fact, after that, I distinctly got the feeling that he was jealous, like I'd shown him up. It's not like I even showed it to anybody, didn't embarrass him in public or anything. Just that I could do something he couldn't.
Then a few times I've been hired for one job description only to find that few of the items in the list really applied to the job. That's really annoying, since you have to pretty much match the job description in order to get interviewed. Then to find out "oh, we don't really do that here" after you're hired. Grr.
