Ventajas
NVIDIA's PTO and Sick policies are compassionate and generous.
Managers listen to employees' ideas.
Employees get to work on a wider variety of projects than expected, and usually work closely with other teams to get things done. Collaboration is tight almost all of the time.
Desventajas
Employees don't always get insight into why they were assigned a particular project, or have much if any choice about what projects they get to work on.
Managers are often too busy working on projects themselves to have the free time to meet with employees on a regular basis. This leads to short-term, reactive thinking rather than long-term visionary thinking.
