Pros
Big company, big potential for impact, IF you can navigate corporate politics. Tons of options for type of work, Amazon does pretty much everything and internal mobility is encouraged. Retail, entertainment, payments, cloud, hardware... When I joined, Amazon was tough, but fair. Data-backed arguments were valued, and anyone could bring a document to the table. Because it valued ideas over people, and promoted based on results only, it had a surprisingly good gender ratio and ethnic diversity for senior engineers. You can still find pockets of that data-driven culture, but they're shrinking. Leadership principles are great, when they're followed.
Kontras
Amazon is increasingly about who you know and how confident you sound. Senior management no longer takes the time to poke holes in one-way door ideas, and the number of arrogant narcissists just keeps growing. HR can't stop leaders from purging orgs to surround themselves with loyalists and yes-men. Benefits are slightly below par for big tech, as is pay. 5-day RTO is a mess. The only upside to the layoffs is that maybe physical infrastructure won't be totally oversubscribed anymore.
