Pros
It's fun to work on gigantic chips that make a difference. Your work is used by a lot of people. End markets are high volume. And are meaningful: Top 500 supercomputers, medical & scientific research, industrial designers, in addition to the joy of gaming... Superb senior management By high tech standards, the work-life balance is decent Innovative culture -- "failure" is tolerated within reasonable bounds.
Cons
Can be chaotic at times. Large teams means communication overload and sometimes-oppressive check-in requirements It's starting to become a large company, complete with mini "fiefdoms" Nvidia has always been competing in ruthless markets, and the past is littered with dead companies that couldn't keep up. Schedules can be quite aggressive, especially for certain teams. There's no guarantee that Nvidia will survive the next 7 years. But I wouldn't bet against it either.
