Amazon reviews

Amazon.com, LLC treats its employees probably the worst of any "top-tier" tech company. The number of truly useful benefits they have is small. Their claim that the cash you're making makes up for the lack of benefits is incorrect -- other companies are now paying more with better benefits. You feel like the company doesn't care about you or your job. The attrition rate is so high that most teams lose about 50% of their talent every 2 years, so there's a lot of technical debt, and you risk finding yourself on a team whose only job is to clean up legacy code that nobody has touched since 2005 -- you don't get promoted that way, but someone has to do it. The company wants to put all its engineers on-call. If you're not on-call, you're working to become on-call. There is little-to-no ops layer, such that they restrict when you can take vacation during the Christmas holiday. They will page you whenever they decide they need you, including if you're on vacation. The likelihood that you'll get fed up with the company and decide to rage-quit after ~2 years is very high, don't plan on being at the company longer than that. If you're a pregnant mother or expect to become a mother -- forget it, don't even consider this company. They demand too much of your time, and they will make you feel like you have to choose between your job and your baby. Check the list of "top tech companies to work for" anytime from the beginning of time until now, you'll find that Amazon is rarely if never on that list, and there is a reason for it.

You have two choices: Burn out with over-work, or play politics to save your skin. Promotions are based on favoritism in many cases. If you complain to HR about abuse from upper management, be sure they will rat on you and collude to destroy you. Leave before it gets to that.
