I've also had engineering friends that worked for Amazon, none of them had anything positive to say about them. One interesting situation is that one of them worked for Google for several years before moving to Amazon. Less than 2 months later he quit working for Amazon and went back to Google. I've read articles claiming that Bezos had certain opinions about people being lazy, and that he intentionally structured Amazon to make it almost impossible to get promoted. Basically, people are hired to do a specific job, and they will never be allowed to do any other job or be promoted until they quit from overwork. The exceptionally few people that both deliver the impossible and don't quit over the workload are treated as valuable, but only at the specific job they are currently doing. From what I've been able to piece together, this was always at least somewhat true, but has gotten much worse the last few years. I think Amazon is likely going to start running dry on willing candidates in their engineering and management teams within a couple of years and we'll see them start to lose market share as a result.
