Amazon Software Development Engineer (SDE) I interview questions

Medium level coding questions were asked. First question was from graph data structure and second question was of array. Then their was behaviour round in which they asked about the work culture of previous companies.

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
