There were 3 rounds of interview. I was contacted through a 3rd party recruiter for the position. One round of interview at recruiter site and 2 rounds at Nvidia. Round 1: To guage Technical capability. Interview was for 30-40 mins. Round 2: Manager round, to check stability. For 40-50 mins. Experience: The interviewers were amazing. I felt like I was just in a formal discussion and not an interview. There was a long wait time though. Had to wait for 2 hrs between the rounds and before the first round as well.
