NVIDIA Software Engineer interview questions

After applying online I was scheduled for a technical phone interview. The interview was ~45 minutes long and was fully technical. I was asked how to write code dealing with bit manipulations, some questions regarding some keywords in C and a full fledged implementation of a linked list based question. It was very difficult to understand what the interviewer exactly wanted me to do. So it was pretty bad.

Talk about my resume and previous research work. He determined I can go for system programming. Gave me a questionnaire. Questions on C programming, ISR, GPU.
