That's opposite of my experience at AWS. It's likely that the culture at AWS has changed over the past few years, it's also likely that there's a difference in culture between teams.
I assume there's some selection bias going on whenever we're able to hire people out of FAANG companies. We compensated similarly, but in theory had a lower promotion ceiling simply because we weren't FAANG. I assume he wanted out of Amazon because he wasn't on a great team there.
AWS and amazon in general espouse all sorts of values relating to taking responsibility and owning problems.
Whats left unstated is that the management structure hammers you to the wall as soon as they find somebody to blame.
During my 10 years, I had multiple opportunities to break and then fix things. The breaking was always looked at as "these things happen" while the fixing was always commended.
In fact, AWS is the least 'blame game' playing company I've worked at. The mindset of fix the problem and not to find some scapegoat is strong at least in my org, I really do appreciate this because it aligns with my personal belief.
