Initial screening with hiring manager, then 5 loop rounds entirely focused on behavioural questions rooted in Amazons leadership principles (aside from one where I was asked some general questions about my experience). It required a huge amount of preparation. Process ended up being split up across 3 days due to annual leave which was the most stressful thing about it. Didn’t get an offer, but received helpful and positive overall feedback, was told I was just too junior for the role.
