NVIDIA Software Developer Intern interview questions

They took an online assessment and then selected only a single guy for interview. The interview was about the concepts of operating systems and object oriented programming. There was also a dsa question.

An OA followed by a 1 hour interview a few days later. The OA had 3 sections - apti, cs, coding (2 questions). The coding questions were easy enough - one was on priority queues. The interview started with intro the they asked questions from the domain I made my projects on (but not directly on project). Then 2 easy-medium DSA questions - to find missing number, to rotate a matrix. Waa pretty easy other than the domain bases questions which were incomprehensible to me.
