I applied through an employee referral. The process took 5 days. I interviewed at NVIDIA (Santa Clara, CA) in Feb 2011
Interview
I spoke with the hiring manager on the phone and then flew to the Bay area for a round of interviews. The on site interview was fairly standard - 5-6 interviews and a lunch interview with the hiring manager.
Most of the questions were focused on my past experience and domain specific questions on multimedia. There was one interview where I was asked a bunch of fairly straightforward coding questions.
