I interviewed at Nvidia in December 2020. The initial round was a phone screen with manager. The screening round had general questions on computer vision ( Optical flow and its limitation, vanishing point and its significance ). There was coding question to check the merging point of two linked list. After this round there was another round focusing on data structures and algorithms and general C++ questions. Two problems from leetcode coding. After the coding round there another round with a senior member focusing on computer vision. The discussion was regarding projects mentioned in resume. Then there were scenario based questions like estimating motion between two frames of images and fitting a 3D plane given a set of 3D points. I could not clear this round, not sure what went wrong since interviewer also seem to be convinced with the answers that I gave and did not gave any counter statements on my explanations.
