I have also worked with a couple who I am not sure what they did. And a couple that I think were actively harmful by not taking actions, letting problems steep, and pursuing pie in the sky solutions ("we could expand from our core product to offer our $internl_tool_that_barely_works, let's overly fund that while customers churn on quality issues")
And fwiw, I have yet to have a positive experience from an ex-googler and it is more of a toss up with former amazon folks. They are simply too used to white glove systems that have had, literally, billions spent developing these systems to the custom problems of these mega orgs.
