Pros
When you work in Amadeus you will definitely learn a lot. Working there and learning it is like to drink from firehose. It is truly supported learning environment with the caveat: Your learning (and career) depends on yourself, nobody else. Moving easy between the roles and the sites. Yes, you can work in Europe and return back. Bit difficult to move to NORAM, due to working visa, but still possible. Biggest employer in Nice Area (French Riviera), big employer in Bavaria (Germany). Working in Nice in Amadeus you will feel like you are the privileged person. In general, Amadeus is a really good company, but this depends on yourself
Cons
All interesting projects done in Europe and NORAM, Australia have leftover. Due to the size of Australia operations difficult to have career progress, but possibly to have in NorAm, and Europe. Not a big fan for agile offices especially during COVID time. Australia bit lucky on this, but still before COVID I got flu many times like never before in my life. male toilets bit stinky (However, I admit, question not to the Amadeus, but to building management, for some crazy "green environment" reason it is flush free.
