Nagarro Senior Software Engineer interview questions

They have around 5-6 rounds which includes 12 min IQ test, Coding round, MCQ round, two face to face technical round and HR. The IQ test have 50 question needs to complete in 12 minutes. Then the written which has around 3 questions

First round was coding that had 3 questions those were based on the c# concepts like dictionary, list, array list etc. After that there was technical interview round. The interviewer was not knowing much about the latest technology that the organization was hiring for, he was just asking the questions on the basis of answers given by me also he was just trying to prove me wrong. He asked me number of questions and argued to prove me wrong in each question. I felt that he was not much interested in hiring, he was just wasting his and my time that's really disappointing.
