Their onboarding experience is incredibly regimented and planned out for 60-90 days. Day to day tasks, goals, etc.
Know what it was missing? The people. I was 100% isolated from others and the people who excelled at amazon (that this process did not bother or disturb) are those who like isolation and do not want to be social. Reaching out to them during my onboarding time was a painful lesson in transactional communication alone.
My best experiences have been recharacterized by my experience here - my bar has lowered. If I get connected to people, the workers, the management, and get a sense of belonging or community then its at the top of my list now.
Friends don't let friends join Amazon.
I really enjoyed having a roughly 50-50 split between scheduled presentations/workshops/content and free-time where I was left to my own devices to spend time on my onboarding project, coffee chat with colleagues, ask questions and just tinker round.
Then I helped out with onboarding the next lot of newcomers, which cemented a lot of learning for me.
