NVIDIA interview questions

The recruiter reached out to me. At first, I politely turned it down and offered to refer someone else, but the recruiter was insistent so I decided to apply anyway. After talking to the hiring manager, who I thought I impressed with my credentials, I talked to 2 wave of groups: the first wave of interview was a great experience! After 3 weeks, the second group was a “technical” interview, which was a bit odd to be calling it that. When I reached out to the coordinator for clarification, she mentioned that it’s how they labeled the interviews (even though it was not labeled on the first group). The second interview seems superfluous since the questions they asked are almost identical from the first wave of interviews. Compare to the first wave, the second group was less charming. It was radio silence for 4 weeks. Then I got the dreaded generic “passing-on-your-application” email. Felt somewhat disrespected when companies reached out to you, insist that you apply, make you go through the “song-and-dance” interviews, only to not be considered and not even give you the decency of a phone call on why you didn’t get the role.
