First F2F interview(technical) Interviewer seems to have lack of technical knowledge Questions 1)How many years of experience you have? 2) what is your CTC? (i dont think in technical interviews they supposed to ask question about ctc) 3)Then he asked me some mathimatical problems (Like aptitude test) #Middle of the interview he got call from food delivery guy then he went to pick up the delivery and brought his food inside the interview and started eating and making noise. ##Soo irritating 4)He asked me about my current project. I explained for 20 mins he did not understand anything.Then he told me you should explain like illiterate person also should understand(Finally he agreed on that he is illiterate) Then he asked me some simple programming question which I solved in min so I dont even remember the question. Then because his ego got hurt he took his laptop and asked me programming question after searching on google for 2 mins. I suggesting the ways and he was not agreeing on any one of that i think he was expecting exact same answer like on internet. After this interview i lost the interest in company then they took two more interviews which were taken by senior people and interviews were mostly based on system design
