Nagarro Senior Software Development Engineer interview questions

Interview on 06-Jun-2019 on "371, Jwala Mill Road Electronic City, Phase IV, Sector 18, Gururgram, Haryana 122022". "An interview in Nagaro" is only for fun and they wanted to make fun of the job seekers. It's a waste of time and money. This is the second time with me in Nagaro. after waiting for 5 hours, A very tired interviewer came and started taking interviews. He gave me some problem and went to other interviewee. He was interviewing 3 candidate at time because of lack of proper arrangement of the interview panel. And repeatedly going to those who were giving interviews on same time. After not answering only one of the 5 questions, gave me away and did not give me another chance. it was kind of escilation round.
