Amazon Graduate Software Dev Engineer interview questions

Invited to online assessment, was split into 2 parts. I did not get selected for the interview rounds. They do not give feedback during the online assessment stage, so it is unclear what needs improvement.

they sent me an email to prepare for a 4-hour home test. the test started with 1.5 hour 2 leet-code questions. an hour after completion, they sent me a link to a behavioral test based on amazons 14 leadership principles. super crazy test 2.5 hours test where they put you in a like 'Teams' environment and they send you a lot of emails and chats, to see how you would deal with a work environment. After that, the test ended with 100 personal and quite weird questions. More than a month passed, and they reached out to schedule a phone interview only after I sent them an email to ask what was going on??? Had the phone interview and did not pass it. The process should have continued with 3 consecutive interviews each an hour with 3 different interviews, 2 technical, and 1 behavioral. I really don't know how is it possible to pass all of these stages. amazon is CRAZY!
