Several. In fact I currently work in such a company. When I left “hierarchical” Microsoft for “flat” Google many years ago, there were 6 layers of management between me and Ballmer, and 7 between me and Schmidt. Back then it didn’t really matter because the company was bottom up and management did not interfere much with what was going on (“controlled chaos”), but now during my more recent stint there there seemed to be a lot more gatekeepers on everything “aligning” with one another without fully understanding wtf is going on. As someone very technical and very senior at the same time that was kind of frightening to watch, like a slo-mo trainwreck when you’re within the blast radius
