NVIDIA interview questions

I had 2 rounds. Questions started with resume work I did and questions on multisensor fusion. First one focused on resume, OS, cpp OOPS concepts.CUDA and bit manipulation questions. Second rounds was mostly on coding Array, and medium level questions

1st stage: HR contact around 30mins. 2nd stage: Online test for regarding to Linux operation experiences 3rd stage: Online face-to-face interview with two engineer with two Leetcode hard exams. No other interview anymore, stopped at 3rd stage interview. Not really easy for the LeetCode even though I didn't get clear about the purposes of that Leet Code exams.
