Started by recruiter approaching me and scheduling a second round with a senior SDE. He was pretty uninterested and rude. At the end, he said, "I don't have time. Finish this and ask any questions if you have, or let's disconnect." The tone was too rude, and I felt sad, but I finished the code. The only reason I disapprove of NVIDIA's interview is because of this guy. Otherwise, if you get someone nice, then maybe it could be a better experience than the one I got. But a piece of advice to whomever is reading this: never get depressed. You can do it, just as I did. Even if I got rejected, I did finish the code.

Explain challenges in your project. What was your contribution, and why NVIDIA? Followed by an OOP question and then a coding question, which I would say was Leetcode medium or hard.
