NVIDIA interview questions

Ghosted after loop interviews. A friend intro'd me to VP who intro'd me to Director who was the hiring manager. After talking to hiring manager, had loop of 4 interviews and never heard anything. I prepared a lot for the interviews and thought they went well (although apparently not well enough to get the job). I'm just surprised neither the hiring manager or recruiter ever contacted me again, and they did not respond to my follow up message. It's a pretty bad experience.

First they presented a little presentation about the job and company. Then asked about my resume, grades, courses I took etc. Then went into the actual interview. The interviewer said that the interview would be theoretical but it wasn’t. They gave me two questions, each one we discussed deeply. I still don’t have an answer regarding the next interview but I don’t think I’ll get it. I was not on top of my game because of one course I took three years ago and also because I was told that the interview is theoretical, which it wasn’t. The interviewer insisted I get interviewed very soon even though I communicated that I have finals and that I need to refresh my knowledge of the course I took three years ago. Bad idea. I did not like the interviewer; he was pushy, and too strict. Also his questions were designed to trick which just took away my passion of working for them. For example, I would answer correctly at the first time and he wouldn’t tell me, but ask questions in a “are you sure?” manner. I also could explain with another physical and valid explanation but he would want very specific explanation in his mind (sometimes you can tackle a question more physically in different ways, or mathematically, etc). So that mostly what made the interview difficult. I do not think I’ll get a second interview but even if I did, I’m not sure I want this guy to be my boss, it doesn’t sound promising.
