Vantaggi
My immediate teammates were genuine and caring people who supported each other through some pretty harsh times. The leadership principles are actually pretty well thought out.
Svantaggi
My team was handed a failing product created by a former team that rushed to ship and quit as soon as they got promoted. We were treated monstrously by leadership who quite literally yelled at us in closed rooms for being unable to save the failing product. Hours were long, sometimes 12-14 hours a day. Operational post-mortems were used as punitive threats instead of genuine opportunities for improvement. Oncall weeks often reached 10-20 pages a day. Multiple company-internal tech debt management consultants were brought in to help but gave up after no impact was made. High SDM turnover meant that nobody was available to advocate for the engineers, nobody got promoted, and tribal knowledge was lost. I could not have had a worse experience. Recruiters email me every few weeks asking if I'll come back. Obviously other teams are different, but the potential reward is not worth the risk. If you can get a job at Amazon, you can get a job elsewhere where you will be treated better.
