I Got Fired from Amazon as a Software Development Engineer

I also work at Amazon, and I can tell you, your experience was pretty unique. Some teams are worst than others, of course, but no one expect you to pick up a project by yourself, fresh out of onboarding and own it end to end. After you clear your interview loops, you get the chance to match with several teams (not always) and that is your chance to figure out what the team does, whats the situation over there, etc... if you were hired for a specific team, and you feel is a bad match, you can talk to your recruiter/hiring manager and they will find you another team. Is more expensive to let you go, after you cleared the interviews, than to send you to another team. Most teams are always hiring, they even pouch engineers from another orgs, etc... I'm by no means saying Amazon is a paradise, as I said, it highly depends on the team. But for them to fire you like that you have to be doing pretty bad, or maybe your manager felt you were a bad person. For other folks reading this: The team matching rounds are *very* important, if you get assigned a bad team, you need to react quickly, and move on. I feel sorry for OP, I wish him/{*} well.

It's always interesting to see the ratio of green names to normal names in these threads.

I won’t comment on whether the action is justified or not in this instance, but:

Never hang up on a colleague. Ever. As far as social phone etiquette goes that’s probably one of the most egregious things you can do.

Instead, humble yourself, politely disagree and document over email, copying another colleague who witnessed, or if unavailable the manager (in this case the skip).
