Can't Get Promoted

Amazon is supposed to be a data-driven meritocracy, but after almost 5 years of getting good 360 feedback and beating all my goals, I finally gave up and left since my managers refuse to put in any effort to promote me. Like most managers at Amazon, all they seem to work on is whatever helps them to get promoted and when I've asked about promotions for me or the other SDE's, they tell me that I'm not ready yet without actually going through my performance data. I'm much happier now at Google since I got promoted right away and I can keep driving my career forward without any selfish managers blocking my way.
