Amadeus Data Scientist interview questions

I interviewed for the Air department of Amadeus via Alten. The interview took less than 1 hour effectively. However, the Amadeus interviewer (direct manager) was ~30 min late. I got this interview via Alten, who contacted me after having found my CV online. The Manager at Alten was super nervous and treated me like a kid fresh off University, even though I have experience. I got the Amadeus interview after a couple of Alten interviews by phone and a C++ test. Overall no thought questions but you realize they don't care about you, you are just a number. Found out 10 minutes before the final interview to which Amadeus department I was applying to. Nobody told me at any time what was the exact position I was applying to. After the interview, it was not clear at all what would have been my tasks there.
