Nothing about this surprises me. Google is an engineering driven organization that has no idea how to utilize PMs properly and where being the “smartest person in the room” is incentivized so there’s little to no humility and curiosity and it’s more about individual “winning” than best outcomes for customers; if you operate in a mutual learning way you’ll just have worse but more aggressive/ambitious people end run around you. These things are fixable (and there are some pockets in the company that don’t have these pathologies) but there seems to be little interest in doing so company wide.
But maybe I’m just a disgruntled ex-employee who prefers a Satya Nadella to a Sundar Pichai.
