I had an interview where the tech lead was typing on her computer the whole time and didn't seem to focus at all on the interview. At one point she asked me a question and went straight back to typing. When I was done with my answer she didn't even acknowledge it - the manager had to jump in and ask me another question after about 10 seconds of silence.

They offered me the job. I turned it down. The manager was surprised and asked me why. I told him about that part of the interview and that if she wasn't able to give me any attention to even acknowledge my answer to her question, then I doubt she would give me enough to guide my work or lead me. The manager gave some weak excuses and practically begged me to take the job, even contacted my current manager at the time to pressure me. I still declined. No way am I willing to jump in that dumpster fire of a team.
