NVIDIA Developer Senior interview questions

Did two screener interviews, then a slate of 6 interviews across two days (1 hour each), over the course of 2 months. The interviews themselves were a bit of a mess, with 3 interviewers needing to reschedule, 2 interviewers coming clearly unprepared with questions, another mainly talked about how impressed he was by my current work. 1 interviewer started throwing shade on my current employer during the interview/ It's now been over 1 month since the last interview, and recruiter is non-responsive -- my understanding from a referring friend is they've probably taking a transfer and are just ghosting me. Overall -- nvidia's engineers and recruiter felt disorganized and unprofessional. I didn't get an offer, but didn't feel like it would've been a culture fit for me.

I had a referral, so I was directly scheduled a 45-minute virtual interview with the hiring manager. They were 15 minutes late, and clearly did not read my resume at all. I have 20+ years of experience and the only question that they asked me about my skills and experience was "tell me one thing you did at ." That's it. They didn't ask anything about my past projects, teams, skills, accomplishments, just tell me one thing you did in 20 years. After that was a coding question. I solved it in one line, but they said that I couldn't do it 'that' way, so I spent the next 20 minutes figuring out how they wanted me to solve it. There was no discussion, just me thinking and typing out code while they clearly did emails or whatever on their other monitor. Not engaging whatsoever. At exactly the 45-minute mark, they said "our time is up, sorry but you don't have any time to ask questions about the job or company, bye" and abruptly logged out. Super unprofessional in my opinion and a colossal waste of time. Generic rejection email within the week.
