Wildly different per project. My team is a boys club at the top. One regime was ousted to allow for a new dictator who filled the high paying ranks with his buddies from outside the company and bootlickers. Their mission is efficiency for the sake of efficiency. You will be granularly nitpicked every hour of every day. Management expects you to go above and beyond (i.e. not in your job description) at all times with a slim chance of being rewarded for it. My manager doesn't care about my career, will not invest in programs to strengthen my capabilities, and actively blocks attempts to laterally move to other projects with clearer career paths by making veiled threats to their leadership regarding "poaching." Management reviews were taken away around the time the regime changed. Reason given was "of course people don't like their managers, it isn't valuable to constantly get rid of managers because of few salty employees." It is evident that management has no idea how to run a review cycle or what to do with that data, aside from telling people that they aren't doing their jobs when they aren't consistently over-achieving. You will do well here if you had over-bearing parents who criticized you for getting As instead of A+s.
