NVIDIA Software Engineer Internship interview questions

The first interview was with the manager of the team. It was 1,5 hours long, and consisted of a ~50:50 % split between technical and non-technical questions. The second interview was an hour long, and was a ~75:25 % split between a technical question and questions about my personal projects and passed experience. The third interview was 45 minutes, and was a non-stop onslaught of technical questions ranging from caches, to type representations, to data structures etc. After 45 minutes he said he had to stop because the time limit had been reached. This interview was intense. For the first interview, the skills and assets listed on the job posting were a very good representation of what sort of questions I could expect, but the second 2 required general computer engineering and system software knowledge.
