Here's a key thing that people miss about amazon-- it is NOT a tech company. It should not be mentioned along with Google, Apple & Facebook.
Amazon is a retailer, most of the employees are retailers and the whole management structure is retail guys. Not engineers. Outside of AWS there's very little engineering resources at all given what they need to do, just to maintain the core business.
They're running 20 year old code that 10 years ago was crashing regularly-- eg Amazon.com going down so you can't b uy cell phones or whatever.
I've worked for a lot of startups and a lot of big tech companies, like Apple, Microsoft etc. Amazon is not a tech company.
If you're an engineer you should never go work there-- the management is all non-engineer types. My bosses training was to be a prison guard! He could barely handle excel but was criticizing our code. His boss was no better- a DMV reject. (literally), and all the way up to Bezos who is not an engineer either.
My boss, by the way was dealing weed in the PacMed garage to other employees. The entire team left because he was such an asshole-- and he got promoted as a result!
Company is pretty much a joke.
I know on HN you're not allowed(?) to say negative things about big "tech" companies. I may be shadowbanned for ti, but Amazon was a terrible, TERRIBLE place to work. Microsoft had too much bureaucracy and was too "corporate" for me, but you can understand why they were the way they were-- amazon on the other hand was absolutely terrible. It's run by people who are extremely arrogant and have no regard for anybody -not investors, not suppliers, and least of all employees. It is the most employee hostile place I ever worked. All advancement is political and because of stack ranking its really easy to stab people in the back. Terrible company. (I've had a lot of jobs, worked for disorganized startups-- but the key difference is whether management gives a damn about employees or not. Amazon they don't, they're hostile, everywhere else has not been that way- even bad management is usually just incompetent, not hostile.)
