Hard to place the blame on a single person, though I do think a "management consultant wearing an engineer costume" captures Google's engineering leadership these days
Yeah. But what do you expect when the boss comes from McKinsey? Not only does the place teach a particular skillset, it also selects for very peculiar employees. It would be downright weird if an ex-McKinsey employee were anything like a decent engineer.
Are there known examples of ex-McKinsey employees that are generally considered a force for good in general?
