Amazon

They sent me OA1 and OA2. Later, I did not receive any communication, possibly because I didn't pass all test cases. However, I hope to hear back from them soon.

Initially, I received an email for an OA, which I completed and passed all test cases. After two weeks, the recruiter reached out to schedule an interview. One week after that, I had a 60-minute interview.

There were 3 or so rounds. The first round was a debug round with easy questions. The second round involved 2 programming questions in your language of choice (I chose Java). The third was a behavioral round. The first three rounds are automated.
