Yes. Although in my case when I was talking about my 'best managers', they were also the people who were brilliant and were really good at the tech side too. These people all just had a natural ability to navigate through the political BS while still being extremely competent software folks.

Mentors and leaders.

HR.

Those are stereotypical bad managers, not ALL managers. I know a lot of great managers who are not like that. And even the ones that failed didn't fail due to malice or vanity. Most people I've encountered want to build cool things, even the managers, and they often know their strength is not in coding.

Bad managers, sure. Not the sort that I'm talking about.
