Amazon Software Development Engineer I (SDE I) interview questions

Gave the OA. 1 medium, and 1 hard leetcode question. Behavior was easy. Got an email to schedule the interview, never heard back. After months of emailing they told that role has been closed.

three rounds back-to-back (3-4hours), first is BQ round, next two are coding rounds. they prefer BFS or DFS style coding, and heap. medium to hard level. no original questions on leetcode, the questions are a little bit long.
