Amazon Software Developer Intern interview questions

The first 15 min the interviewer asked me some behavioral questions according to leadership principles. Then I was given a code question, which is find the number that exists only once while others exists twice, and followed up 3 times. Finally I had 5 min to ask questions about the interviewer and Amazon

45 min interview with both behavioral and technical aspects, lots of leadership principle-oriented questions and a pretty simple coding problem. The interviewer was great and I didn't really get stuck with the technical portion but he seemed very patient and willing to help if anything did happen to come up. Overall really chill process.
