Amazon Software Development Engineer interview questions

First OA cleared it. Then 3 onsite interviews. First round - Bar raiser round Second round - 2 leetcode questions(recruiter had weird accent and couldn't explain the question to me) Third Round - Behaviouraland LLD

Long initial assent, then long video interview. Both about 3 hours each, both pretty difficult. Process was overall pretty quick as it was just two stages, it was a lot of technical questions and a lot of questions about leadership principals
