The engineering culture among FAANG companies is pretty much the same because of the industry that they operating in and the location of the HQ. Expand that to military or automotive, aerospace, in non-US companies and you might start seeing different engineering cultures.
Engineering culture at Google is vastly different than Amazon. Even Facebook which is more product oriented and iterates faster than focusing on the "right engineering design" first.
Yes because lots of Google left to join FB. And yet, I've heard everyone say in terms of pure engineering and tooling Google is far ahead. That's still F&G though not AAN.
