Amadeus interview questions

They called me in the first place. Started by phone interview (positive). 2 assessment exams one foreign language and one programming (both positive), 1 hour HR interview (positive), 1 hour technical interview (positive), 1 interview with foreign product owner (positive), 1 interview with project managers (positive), then NO RESPONSE. All the process takes more than 5 months.

Technical questions abut the topic of the inter: basic machine learning and distributed environment. Question on Spark and if familiar with Scala. Programming languages used. Description of past projects and academic background. Depends a lot on the interviewer if he goes more technical or more about experiences. Consider also this is an internship position.
