Amazon runs an annual survey with typically quite high participation rates, it is very detailed, and the results are often illuminating (and like many things at Amazon, widely accessible to all people).

Yeah, but you can't see stuff outside your group, I imagine? I mean, dis-aggregated, to drill down to team level.

OP was making it sound like you could get the results for a specific team you'd want to transfer to.

What OP was suggesting is exactly what you get. You can see results at the level of any manager and zoom out recursively.
