I am a SDE at Amazon and I can tell you for a fact that so far the majority of the projects I've been involved roll out exactly like this. The excuses vary, and fortunately I haven't seen the inclusion card in play yet, but all the gaslighting and sacrificial lamb elements and shifting responsibilities and career tactics are ever present.
> if you were hired for a specific team, and you feel is a bad match, you can talk to your recruiter/hiring manager and they will find you another team.
I have to call bullshit on this. Either you play that out in stealth mode until you are sure the other team picks you, or you are in a world of pain. As soon as you click on the recruiter button, your SDM and senior SDM are notified immediately, and if you are not in the best terms with them they can and more often than not do screw up with your plans and even your job. There's a horror story around my corner of the org of someone who wanted out of his team and simply did what you said should be done, but long story short his transfer was sabotaged by the SDM who afterwards placed him in a performance improvement plan with no return.
> But for them to fire you like that you have to be doing pretty bad, or maybe your manager felt you were a bad person.
No, not at all, at least from what I see on a daily basis. All it takes is that you get in the way of your manager's career goals. They have attrition metrics and goals and you have your yearly Forte to cull the herd and keep the average tenure below 3 years.
