Oh, trick question again. Remember we don't want to bash former employers. The interviewer knows if you talk bad about someone to her, then you may talk bad about her one day.

So how do we handle this one?

You could say, "I've never had a really bad boss, but I have learned some things NOT to do." This way you are not directly pointing the finger while still acknowledging you are aware not everyone is a good manager.

Or you could say, "I once had someone that was thrown into management with no experience. He wasn't ready and needed more people skills." Still not pointing a finger!

It would be ok to say criminal, unethical, anger issues, etc. Just don't name names and keep it very short without going into a story. "I once had a manager that was stealing from the company." End of story. Short, to the point and answers the question truthfully.

Think about what you are comfortable with and pick the approach you feel fits you best. I want you to be at ease in the interview.
