I had a boss who never gave me a raise, didn't believe in reviews, and had long rambling meetings where he just said whatever he was thinking. Sometimes it seemed he forgot we were there, and he'd start arguing with himself. He was more "the insecure nerd who got the CTO position because he was the only IT guy when the company started." His management was so incompetent, that they called him "Tallest," based on the Invader Zim joke.
