There were 2 1-hour phone interviews and 1 on site interview with 5 rounds, each with 1 hour. It took one month in total. Very nice interviewers and good interview experience.

In total I had three Interviews at Nvidia, a standard process. First technical Interview with a senior and a group manager. They describe the job and process in detail, and were very positive. It was not 100% what I looked for but the Manager called me afterwards to say I'm a a good candidate etc and exactly what he is looking for and I got a good vibe so I continued. The Second Interview, called technical. However was not asked any coding questions or any hands on question... very weird., and quite low quality Third with HR. I was called to the next interview soon after finishing So I was surprised I didn't get an offer right away, since I answered all the questions. Reason being - they got the impression that I gave the impression that Im not looking for a hands on position. Which felt kind of unfair I also had a struggle with their way of counting experience. Overall, to get in just say you want to work there and code and be OK with whatever the terms.
