Pros
Best technology development in the world. Intel's manufacturing process is always at least 6 months ahead of any other semiconductor manufacturer in the world and is usually the best in class. Intel has beat every manufacturer in the world in producing products with High K / Metal Gate transistors. Incredibly safe environment to work in. The safety of the workers is always priority one in everything that goes on here. Many opportunities to advance with only light to moderate stress levels.
Cons
Red tape, lots of it. Sometimes there are just too many hoops to jump through to get something done. Reliance on others to get projects done can be a pain in the arse too. What would take me only 5 minutes to accomplish sometimes takes a week when forced to relying on someone else to do it.
