How many days does SDE-1 get to understand the amazon stack, get familiar with application and start contributing? Does Amazon provide training for SDEs'?
90 days is the number
After you hear the answers here, make sure to also sit with your manager and hear his expectations and suggestions. It is different from team to team.
Your manager will say 90 days
I’ve heard different ball parks from different managers and engineers. But for SDE 1, I hear it is more about year after year growth and moving to SDE 2 in a few years than anything else.
While I was in Amazon, made first real commit in two weeks. First CM in the first month. My first COE was at around 3 month mark. Took me about one year to comfortably using all the common internal tools (Apollo, Odin and other stuff)
What are CM and COE?
No. When I was there, there wasn’t much help even for interns. Interns were pretty much expected to sink or swim. You can ask for help but you’ll get dinged for not diving deep (important leadership principle) enough on your own if you resort to others too often.
