NVIDIA Software Engineer interview questions

Worst hiring experience I've had with a company. I initially reached out to a recruiter after seeing a position posted. We got in contact (he was nearly half an hour late) to talk about my background and what I was looking for. A week later, I had a screening with the hiring manager and team, which went very well...just a general mix of technical and behavioral questions. I was told from the hiring manager that he absolutely wanted to move forward, so I'd hear back from HR very shortly, and that he'd have my HR contact get back to me with answers to some questions I had asked that he didn't immediately know. And that's it. It's been a month and a half now, and I've heard nothing. My HR contact has ghosted me, despite a follow up I sent over a couple weeks ago. It's clear they don't take hiring seriously at all, and have no problem wasting candidates' time. If you read the other reviews here, you'll find many similar stories. Very disappointing.

They test a lot of basics of Data Structures and Algorithms. Operating Systems concepts and focus alot on C and C++ concepts and programming, questions on Linux were also asked
