Current (long tenured, moderately senior) AWS engineer here. I've been at the company long enough it's pretty clear that I'm a "good culture fit", so take what I'm saying with that in mind.
While I absolutely believe that there are pockets of the company that work this way, more because of sheer scale than anything systemic, I have sat in the annual ratings meeting for engineers enough times, in enough organizations within the company, that I am pretty confident that this experience isn't universal.
It sucks that this author had this experience, and I wish they had said which team that was, so that I could use what social cachet I have to steer people clear of it from inside. Nobody should have that experience.
