My perception of Amazon is that they take everything from open-source but don't actively give back. Amazon and open-source never went hand-in-hand. Making their deep learning frameworks open-source is cool. Kudos to the team which managed to do this. I am sure internally, it must have been a huge struggle to get the approval from execs.

Cons
====
The management process is abusive, and I'm currently a manager. I've seen too much "behind the wall" and hate how our individual performers can be treated. You are forced to ride people and stack rank employees...I've been forced to give good employees bad overall ratings because of politics and stack ranking. Advice to Management Don't pretend that the recent NY Times article was all about "isolated incidents". The culture IS abusive and it WILL backfire once stock value starts to drop. I'm an 8 year veteran and I no longer recommend former peers to interview with Amazon.
== [Edit: Formatted to make it clear what was pulled from Glassdoor]
in my tenure at Amazon, I went from getting a 2 and PIP, then to a 4, then having my promotion held up because my VP didnt like me. Finally when I left to Google they offered SDE3, and another $15k a year. I didn't take that offer.
This was all back in the 2001-2006 timeframe. Sounds like nothing has changed.
Update: They started offering 6 week paternity leave since Jan 2016. 20+ weeks is what other companies mentioned seem to offer.
I just joined so I really am not a statistically significant case but so far it's no where near what was in that NYT article.
Edit: I can't read apparently :) thanks heuving for clarifying and the commenter for reformatting
If you were at Amazon for any length of time and didn't notice the existence of toxic teams and the random chance element of being hired into one of them, you weren't paying attention.
There's nothing wrong with this. There's no contract when using open-source and this is probably how 99% of people interact with it.
