Pros
It's hard to get fired
Cons
In the engineering department, Amadeus has 3 classes of people: 1) Grande Ecole graduates 2) other French 3) foreigners. The first group gets promoted rapidly, the second group gets promoted after 5+ years at the company, the last group never gets promoted and is constantly pushed to learn French despite Amadeus being a multinational company with English as a official working language. Foreigners are hired only as foot soldiers doing all the 'dirty' work for the French elite. In engineering there's no career, at most it's possible to become a team leader (if you're French). Engineers are not transferred abroad either. Salary doesn't grow. All tools and codebase are a mess and broken. It's the same crap over and over again. Contractors behave like employees, don't expect any respect from them just because you're staff.
