NVIDIA Engineer interview questions

I was selected through campus interview. I had solved some previous year interview questions mostly the based on State machine related and timing violations. There was one Aptitude test which was easy and an interview. Perceptions: People: Very friendly, Competitive, highly skilled. It will be a great experience to work with them. Office: Nice place to work. No additional benefits though. Culture: Work , work and work until you get tired. No team outings, not an interesting to place to work at. In fact there is no culture other than work.
