Many are on the gravy train and will do anything to protect their positions. Be wary of incompetent lazy management doing as little as possible. They will be the first to sacrifice you in order to keep their RSUs and maintain relations with the boys club. They claim to have built a culture when the reality is they have imported one from elsewhere, with many existing relationships over a decade. They are so far behind in process and practice, they can only be described as a bodyshop.
As others here have said, as long as the growth and numbers keep rising, the core group will be protected and given free reign to do as they please.
