Pros
Exposure to state of the art fab/equipment, decent access to trainings, reasonable benefits package, and good short term learning opportunities.
Cons
By combining the content of the vast majority of previous reviews, you will have a very good idea of what's like to work for GF: Poor work life balance, inefficient management practices such as too many meetings and little action, poor guidance from team leaders due to either lack of experience or their inappropriate background, constant change of plans/priorities, overall chaotic environment, and very limited/unlikely channels for career growth to name a few. It's hard to understand how such a business strategy can be in place with the expectation of any kind of success. Employee morale, which should be the driving force of a successful company, is going downhill across the entire organization. If you plan an enjoyable career in the semiconductor industry, GF does not seem the right place to be.
