Pros
Almost no bureaucracy in R&D!!! Job allows for creativity and innovation yet is also challenging. There's always an opportunity to learn here! The benefits and time off are unreal, the Santa Rosa campus is beautiful, and everyone is nice and helpful. The work life balance is amazing too -- you almost never have to work overtime and no one is breathing down your back to know when you come in and leave each day.
Cons
The products we make aren't that interesting unless you're a die-hard electrical engineer; and you'll struggle to explain to your friends what the company does. Santa Rosa is also a sleepy bedroom community and is not the best place for recent grads to move to and try to make friends. Keysight is trying to create a better sense of community among the younger engineers, but it's not quite there yet.
