Pros
I liked my manager and am still close to them today.
Cons
They were terrible at hiring internally, and would frequently hire people (ICs and "managers") they met out at bars. And, one day, you might wake up and see they've hired a friend of a board member to take over your team, when you already had a manager and did not get to meet them until they already signed an offer letter.
Then there is debacle whether they are actually fit to be your manager, and they hang up a zoom call in your face because they disagree with you. So mature!
