No transparency

At Amazon, there is no transparency when it comes to career growth. It doesn't matter what you actually achieve or how many things you know, learn or change for the better. If your bosses have friends they want to promote, then you have no chance.

Also, you inevitably gain more responsibilities over time, but your wages won't reflect that since you're not actually getting promoted.

Someone from the outside has a better chance of landing a higher position job than someone already working there, so don't think that you can start low and then grow.
