NVIDIA interview questions

There is a Pre Interview to get shortlist for the main Interview. Its named as HackRank. After that they have 3 more interview rounds. I have attened 1st round and waiting for the results.

I received an email from NVIDIA saying that they are interested in conducting an interview with me. I had a couple of questions. The contact provided was with the interview coordinator, who shared the recruiter's email address. He told me that if I had any questions, I should ask the recruiter. I emailed the recruiter and never heard back from her. So I went straight to the technical interview without a “recruiter interview” or even speaking to the recruiter once. During the technical interview, there were two engineers present. They were clearly not prepared. From my assessment, it looked like they didn't even have experience conducting interviews. The questions were like this: - Do you know which Linux command you can use to check running processes? - Yes. 'ps'. - That's good. Do you know which command you can use to check free disk space? - Sorry, I don't remember. - That's bad. That's it. No follow-up questions. No questions of substance. Just trivia. Nothing that would require an understanding of engendering concepts or experience in software development.
