My current manager is very technical, we work in a FAANG level company, and he was an IC not so long ago. He's a micromanager sort, suggests it's okay if people want to work over holiday days, and tells people regularly they should be thinking about how to contribute at all times (while they're home eating dinner, taking a shower, on the commute, etc.). He's the second worst manager I've ever had. The worst was also a former engineer, but he liked to play politics, lied about just about everything, and regularly blamed delays and failed projects on his team. No engineer was spared--every single one of us ended up with negative comments on our performance reviews for periods where we were assigned to high visibility projects. It got to the point where nobody on the team wanted to work on any such project. This guy was promoted to a director position eventually. Some managers suck. Some don't. And it doesn't matter if they've ever been an engineer or not. Also, engineers aren't special here: talk about egos and negative, hyper-competitive behavior....
