I applied online. The process took 4 days. I interviewed at NVIDIA (Santa Clara, CA) in Feb 2008
Interview
HR was pretty responsive. The interview process was conducted well. There are definitely lots of smart people at Nvidia. The interview itself was thorough but not completely relevant to the position aplied for.
The process took 4 months. I interviewed at NVIDIA in Sep 2009
Interview
Had multiple phone interviews with the hiring manager and other engineering members of the group. The interviews consisted of mostly technical questions pertaining to the job. Highly technical and detailed questions down to the transistor level. Had about 5 phone interviews each 1 hour long. Then I didn't hear anything for a couple of months from either the recruiter or the people I interviewed with. Then I was contacted by the recruiter again and was brought in for two 1on1 interviews of about an hour each. These interviews were similar to the phone interviews and consisted of mostly technical question. I was told that I would hear from them in a couple of weeks, but they never contacted me again. Not even to say I wasn't a candidate anymore. That seems to be the way companies interview now - they talk to you and then if they are not interested, they don't even contact you to tell you.
