2 interviews, needed to implement min stack at the first one using linked list needed to implement lru cache needed to explain about a project i did was also asked basic questions about myself

1. Online assessment - sent to me about a week after submitting CV. Had 2 weeks to do it. It's 2 leetcode questions (~medium) so practicing helps. Not a complex algorithm but requires thinking, creativity and discriminant. Got all test cases passing in both questions. All instructions are in their email so no surprises. Then some reliability tests (100+ rapid questions) which I believe we all pass , just say the truth (I've submitted the assessment in December , then only in April got a poitive response and scheduled for an interview) 2. Online interview - U have 2 consecutive 1 hour (total=2 hours) online interviews with Amazon employees. Both w/ exactly same structure - personality questions whihc U R expected to answer by Amazons B**lshit leadership rules and then leetcode kinda question, again ~medium level. You are expected to think out loud. Had one with logs sorting and one with parking lot managment, succeded both in optimal solutions (don't worry, got the most general rejection email with no explicit reason 4 days later) overall - was professional yet no clarity neither reason for non acceptence. never had this kind of experience and i've interviewed for 15+ job places in hi-tech before. Kinda aligns with what people say about Amzn
