NVIDIA interview questions

The internship I was applying for was in Santa Clara CA. It was a round of 3 phone interviews. The first one was general technical questions, some brain teasers and some behavioral questions. The second interview was a coding interview with only one question to solve. You have to code it in C. you can't use any other language (makes sense because they do mostly low level stuff). The third one was also a coding interview with a couple of questions. The same restriction about the language applies.

Applied through campus career fair. First round was a basic technical interview involving basics of programming such as pointers, algos. Second round was a coding round where they asked certain questions on algos
