Amadeus interview questions

Before Interview I was told that entire process will take 2-3 hours and two rounds will be there (1 technical and 1 manager) but it took more than 7 hours to complete 2 rounds both were technical . I was surprised when 2nd round interviewer was asking whether these questions already been asked by you first interviewer or not. I didn't come across with any DS and algorithm related question during entire process. I will suggest don't waste your weekends for attending interviews in amedeus. I found very less people (5-6) but still it took 7-8 hours for 2 round process . After this I didn't see any response from there end .
