The interview was a technical phone screen conducted via video call with screen sharing. After brief introductions, the interviewer asked about my Java experience and previous projects. Then we moved to a live coding challenge where I needed to solve an algorithm problem in Java. The interviewer was collaborative and provided hints when needed. We discussed my solution approach, time complexity, and potential optimizations. The session lasted about 60 minutes.
