General Motors (GM) Sr. Software Engineer interview questions

The interview process began with a phone screening conducted by a recruiter, where general questions were asked. Eric informed me that the process would involve six rounds, including multiple LeetCode-style interviews repeated across three rounds. The first round was an online coding assessment on Codility, featuring LeetCode-style questions. The second round was another easy LeetCode-style problem, also conducted via Codility. In the third round, I spoke with a technical interviewer who focused on my past experience and asked questions related to Java, Kafka, and general backend development. The fourth round was again LeetCode-style coding, and it was unclear why the same type of assessment was being repeated. The fifth round involved a system design interview. The final round was a behavioral interview with Engineering Manager Hussain. Unfortunately, it didn’t feel like a meaningful conversation, as it seemed he was more interested in wrapping up the interview quickly. I felt useless after going through a six-hour interview.
