NVIDIA interview questions

Applied online and was contacted by multiple recruiters over a period of several months. I had one interview cancelled. One rescheduled after the interviewer called in 30 minutes late. Another time the interviewer was 10 minutes late. Eventually I went through 2 rounds of phone interview before they decided not to proceed further. The recruiter was friendly and helpful, but I did not feel the hiring managers respected my time enough to show up on time and make decisions in a timely manner.
