A startup I've worked for in the past had one of the smartest cofounder/CTOs I've ever worked with. He was also arrogant as heck. The engineering team inherited his arrogance and it was quite an insufferable place to work. I left that company for a number of reasons, this was certainly one of them. I get it. When I was young in startups a decade ago I was often called the rockstar or ninja. I was arrogant then too. It felt good. But it doesn't do good for people who come into the company later. The culture is already toxic by the time the team is growing. Now that I'm older, I'm extremely mindful of this behavior now and make sure I don't repeat these mistakes as a team lead. There are tons of other tips and advice for this position too, but this was definitely the first thing to come to mind.
