I am going through my second stint at Amazon and I enjoy working there. However, it is not the best place for everyone.
This will tell you a lot about whether this team is growing and successful, stagnant, or on fire.
Getting paged a lot is a hallmark of teams you don't want to be on, but in the last couple of years, Amazon has instituted policies that make it easier to internally transfer (no strict time limit on how long you have to stay with a team).
Getting paged is sort of a proxy for the real thing you want to know: how many people are voting with their feet.
Ask how long the various managers have been in that org/under the same senior manager/director. A manager who you like that gets along with senior leadership is super important.
Ask questions during your interview. If you interview for an org, you'll be working with most of those people. Most of them won't lie to you because you'll just leave asap or be pissed off that they were full of crap.
This is all much more difficult to do if you're external, once you're in, it becomes easier to figure out if you want to work somewhere. I'm not willing to even consider an internal transfer unless someone I know will vouch for it. Too many horrible teams and a bad manager can mean you need to find a new company.
Previously I believe you had to stay on a team for a year before you could switch. Now it's something like a month.
If you find yourself on a bad team, pop open jobfinder and don't be afraid to abandon ship! Don't needlessly suffer.
