Pros
Nvidia might not be as big as some other big players of the Bay Area, but I love the work ethics. They really seem to care about you, about the environment, about charities, about helping society. I love the culture of transparency, where everything is shared with everyone. You really never feel like they are cheating or trying to take advantage of you, except maybe when it comes to "unlimited vacations", which essentially means that the more you take, the worst you feel. Another strong point is to feel heard. Whether through the suggestion box, through yearly surveys or any other channel, at Nvidia you have a voice. Overall a great place to work!
Cons
Vacation policy. It would be so much more honest to have a set number of days, with flexibility around it, instead of a vague and abstract concept of unlimited vacation.
