There are many possibilities, but you need luck to enter on the right path - Senior Software Engineer Amadeus Employee Review

Technology is too old. The company is really big so it's really difficult to change anything. Final customers are hotels, air companies. This kind of company doesn't need innovation, just a system that works correctly and keep the data secured. Good ideas are lost inside mountains of papers and CMMI rules. If you enter through a service company, it's hard to build up any career path. Often, you career depends on the university you came from, at least in France.
