NVIDIA interview questions

Had got a referral through a contact there, so the HR contacted me over email. I had 3 phone interviews scheduled, one after the other over the course of 2-3 weeks. Nothing difficult, about my resume and some simple programming basics. Then I was called onsite for half a day, where I had 5 technical interviews of 45+ mins each spanning programming techniques, designing, computer architecture, system verilog, c, c++ (i had them on my resume). Most of the interviewers were very friendly, good people. I enjoyed the interview.
