Amadeus Senior UI Developer interview questions

I received a call from direct HR and after some basic screening process got invited to come for an in-person interview. Cleared the first two technical rounds and next was the director round, Had a really good frank chat with him, he seemed satisfied with my performance and resume. So far so good. But when he realized I am from his past company XXX he sent another person whom he would have probably pulled from XXX to just have a casual chit chat. Now comes the guy, the most arrogant, negative mind person I have ever met with zero people skills. He was having some perceived notion about himself and a few things which were making him offended throughout the talk. First of all, if I have been told have a casual talk with 'this' guy I will talk in a casual manner even though you are 20yrs experienced. Now, this offended guy gives negative feedback about me I don't know why and I get a call from the security to leave for the day. Let me tell you till then, the HR himself was giving me feedback in person after each round. Dear HR if your hiring manager rejects for whatsoever reasons at least it would have been decent enough for you not to hide behind and come up say the same. Telling it through the security, not a very professional behaviour to a 6yrs experienced person who took leave for a day to attend the interview process. And to the arrogant guy, let me tell you with this negative mindset, you will probably grow under someone whom you know, but someday another arrogant snake may bite you just like you did to me. PS: I was from the XXX company. They had a great experience with XXX, and they just could not digest the fact that I am not liking to work in their so-called great XXX.
