There's an Old Work Rule: People don't leave jobs, they leave bosses.

It can be extremely difficult during the interview process to determine the true, unvarnished nature of personalities. Next time, be sure to meet with your potential team members and counterparts. Ask probing questions about the bosses management style and company culture.

So move on; quickly now. Cut your loses today if all possible. Chalk up the experience to nothing ventured, nothing gained.
