Amazon Software Development Engineer (SDE I) interview questions

Three-round interview with three technical questions. I thought I answered all the technical questions well. The behavioral questions I was a little unsure of but one of the interviewers was nice enough to reiterate what they were looking for, and seemed satisfied with the answers that I gave. I was not really sure what the deciding factor was but I wasn't hired

I was contacted by amazon internal recruiter on Oct 2021. He gave me extra time for preparing my OA. After OA, I complete 1 phone interview and then Onsite(virtual). Total took about 2 months.
