NVIDIA Senior Deep Learning Engineer interview questions

Very disappointing process. Very unorganized and disrespectful. They dont know what they're looking for and assign random interviewers without having a chat internally. The recruiter never bothered to reply to my emails prior to the interview. Talked directly to the HM, which was a standard screening round. I was explained what the role was and what the expectations were. Finally got a conversation a day before the panel interview where I was provided some choppy info on what to expect in the next round. One interviewer, not part of the hiring team, had no idea about the role or my background. Instead, kept asking about what they knew. At the end, I asked -- "is this related to the role, because based on my chat with the HM, I didnt think this was needed?". -- they said, "not really.". Other interviews were find, pretty standard. I never got an email from the recruiter or even an automated email.
