Audible Software Engineer interview questions

Overall there are 4 rounds of interviews. First-round was an HR phone screen, asked general questions and some basic technical questions about Android (I was applying a position developing Android application). After this was a round of OA on HackerRank, including 2 problems, one easy LeetCode level, and one middle. The third round was a technical phone screen, lasted 1 hour, including several work-experience-related problems and one live coding challenge. The problem was about merge intervals. Finally, was the virtual on-site. Including 5 rounds, each lasted 1 hour. Because of the NDA, can not talk in details.
