I’m not sure if that’s true. 1 dev manager for 10 engineers might be tough. The sheer number of 1:1s would be insane, much less keeping track of the career trajectory of 10 different people at 10 different parts of their lives. I guess this would be less difficult if everyone was already at senior or staff level, but you’d still have so much of that managers time sucked into 1:1s, reviews, and team retrospectives. I’m not even a manager and I start to feel neglected as an engineer once my manager juggles more than 6 other people, because I see they start to forget what I’m working on, and those 6 start to compete for attention to get promotions…
