Pluspunten
Yes, you don't have to worry about no tasks. Everyday there is a huge amount of tasks waiting for you. If you want to really take efforts learn and dig into something, this will benefit you a lot. There's many senior engineers in NVIDIA, from who you can definitely learn a lot.
Minpunten
NVIDIA is a world-famous company, however it is not as cool as it sounds working here ---- I'm comparing it with some companies with equivalent reputation in industry. Base salary and bonus are lower than many Bay Area companies. Benefits are not attractive. Working environment is not so good: only drinking water is free! I cannot comment on the overall management, but my manager is definitely doing too much micro-management. If you are only attracted by it's "fame", be careful on your offer choice. You definitely have a lot of better choices around Bay Area. Just look on glassdoor and find companies rated higher than it! This really helps!
