Amadeus interview questions

First round was SHL test consist of logical and English questions. After that they called on their premises for technical rounds. I have given two rounds on that day before lunch, mainly focused on easy data structure and algorithms questions and little bit from previous projects . After that they said that as hiring manager is busy, I have to come one more day for hiring manager and Director round. Again one day they called me for hiring manager round. As the hiring manager was technical , the round went fine with discussion around designing solutions like e-commerce website and parking lot design. At this point he asked me about my current ctc, expected ctc and my offers. After this he said I am asking a high amount and how can I justify this? I have asked for very reasonable ctc compare to status of Amadeus, I was really surprised with that response. Then he said HR will get back to me and voila I am rejected on basis of technical skills. I really wanted to work in Amadeus and this behavior really crushed my confidence. I really hope this doesn't happen to anyone.
