Good team, good pay, good diversity. That does become a problem sometimes, and unfortunately, there is no channel or way to solve things when issues arise in that domain. Rather, it can backfire if you are a junior trying to solve problems in that domain.

Senior engineers and managers can both easily make your life hell. They will neither try to understand you nor help you properly. Very easily, there can be a communication gap given how busy or "busy" they are.

Often, for a task where a senior's guidance is mandatory and it does not progress because they don't have time, or things are progressing slowly with them in terms of actual discussion because they can't give you 10 minutes from their day, the manager will start asking why that task isn't done.

And if you say anything about the senior not giving you time, then the manager will just say that, "Oh, it is on you still. As in Amazon, everybody has ownership of their task, and so I don't care how, but you have to somehow get the task done."
