You'll have a bunch of peers request feedback from you. Your feedback will need to be specific and focused around the leadership principles. It'll need to include some kind of constructive criticism. The feedback you provide plays an important part of any promotion opportunities. Oh, and naturally they stack rank, no matter how much they say they don't and try to pretend what they're doing isn't actually stack ranking, when really it is.

The more time you spend there, the more requests you'll get, so after a couple of years it's not unusual to get 30+ feedback requests.
