NVIDIA System Software Engineer interview questions

Interview process was a bit messed up. The first person I was supposed to meet did not show up until about half hour. Then the second person was called who I was interviewing with and the first person just barged in to say sorry without caring if I really acknowledged it. Then it was people showing up in random order than what I was given the schedule. Anyway I talked from 11 - 3 pm.

I got into nvidia through college placement. I did my ME project in computer graphics and they were also looking someone having good knowledge of computer graphics. There was no HR round. I mostly explained him about my project and answered some basic graphics questions.
