Oh my goodness, ignore the people who are telling you "just quit if you don't like it." If you take the job and it's a huge pain, they will be the main ones judging you for not liking it and looking at you as if you were insane if you actually did quit. It's also a tough situation for you because once you get into an annoying job, getting out just isn't easy, I had that happen with my last job and the one I have now that's just as annoying and is only a few cents above min. wage.

If you are seeing red flags, don't ignore them. In every 'opportunity' I've ever had I've blatantly ignored what I've known to be true to appease other people and every time I've kicked myself. There is the chance that this guy could be moved or something and you may not have to deal with him. Micro-managers are a huge hinderance but what type of management does he have? If he's legitimately doing things wrong that are hurting business, his superiors may be giving him enough rope to hang himself.

If you do decide to take the position to always CYA.
