I was called by an Amadeus representative. I had the option of doing the interview in English or in French (I chose English because it's my stronger foreign language of the two). It was very hard to understand his English due to his French accent.
He asked typical interview questions such as: tell him about myself, what are my faults, do you like working in groups or alone, why did I chose computer science, what do you know about the company, etc. There were no technical questions.
Overall, he was nice and the phone interview lasted about an hour. Sadly, I was not hired.
