Wasn't too terribly impressed with the team (and a couple of them were definitely giving off that "I hate my job/life" vibe, one disgruntled fellow was even trying to drop little thinly-veiled "run away!" hints at me). I figure either the cream of the crop at Nvidia doesn't work in QA, or they don't get proper support from upper management.
P.S. Didn't get an offer anyway, probably for the best - I was desperate for work at the time and would have taken it :)
