NVIDIA System Software Engineer interview questions

Applied online and was contacted by a HR personnel after about a month. A phone interview was scheduled. The one on one phone interview was with a very senior employee. The interview was very easy and I answered every question correctly. But did not get the offer. Only simple coding challenges and OS concepts were asked.

Applied for the internship through a school listing at my college. Had two interviews, both technical, over the phone. Questions ranged from networking concepts to java specific things. Each interview required coding, demonstrating ability and to use and understand various data structures.
