Pros
Great entry level gig for engineers, salary is great just starting out (65k). Benefits are solid, people are generally good at their jobs. Very hard to get fired, basically need to time card fraud. Great city, and the planes are pretty good. Free coffee. Shifts and timekeeping are very relaxed, it's a "put in your time" kind of place, just don't abuse it and everyone gets along great.
Cons
Benefits have been trending downward as it goes more corporate vs small engineering shop. Salaries stagnate REAL quick after 3 years of experience. No benefit to staying and putting in your time, best served by leaving and coming back later. Engineering facilities are so painful. It's all varying shades of gray cubicles with zero life or natural light. Sodexho runs the pitiful Cafe, and overcharges for crap food. Engineers are also just painful to work with after 40 years old, probably not just GAC issue.
