NVIDIA Software Engineer interview questions

Applied online for the System Software Engineer, Distributed Systems position and recruiter reached out to me to set up a 45 min interview over Teams. Interview was with one of the engineers for the team this position was for. We talked about my previous experience and the role for 15 min. Then he had me do a LC question via HackerRank. Last 15 min was for questions. Thought I did fine, but received a rejection 2 days later.

First there is an online hiring test, then three video interviews, asking about your background, some basic knowledge and codin tests. After that, there is an interview with the hiring manager.
