Nagarro Software Engineer interview questions

First of all this company has no professionalism, I was selected for CSD role I had my first technical interview, first of all interviewer came late without asking any introduction he asked me about Java, I answerd it, then he asked few coding questions that were easy, then he asked me some DSA questions i answered every question, then he feel like I don't want to higher him because he knows everything, then he says I'm done with your interview good buy what kind of interview was that. If you are not interested to come to interview why are you even come and wasting others time too.
