A small part of the problem that's I observed during my interview there is the person who interviewed me mentioned that the teams largely operate independently, and sometimes have competing ideas. First across the finish line wins.

Ultimately, this, I think, sets up a lot of perverse incentives. Engineers are encouraged to burn themselves out to beat their coworkers, and there's less value in maintaining a good product. Anyone who remembers the very early days of their cloud offerings could pretty easily see the results.
