Pros
Amazon has the most solid company structure I've seen. The leadership principles act as a compass for pretty much everything, even everyday life outside Amazon. My experience in Amazon Mexico is that innovation is still a bit tethered to the core business' growth (expected). Newly launched countries normally take around 5 years to take off and then start to truly innovate with riskier bets. Data drives all decisions. I had no idea what "data driven" meant until I joined Amazon. My ability to analyze and dive deeper into data in order to find solutions has grown exponentially in 2 years. The company's stock has risen like foam through the years, which is specially good when a part of your income comes from RSUs.
Cons
I find bureaucratic processes to get in the way of moving forward more than I expected. We have many mechanisms to escalate and resolve, but some processes get dragged on for longer that i would like. Amazon culture is a bit cutthroat, not everybody adapts to the fast pace of the business and receiving call outs in a constant basis. This translates to a high attrition rate, which in turn lowers morale.
