2 questions. 1. Tell me about yourself. Interviewer asked me this and as soon as i started, light went off. I also stopped speaking. Then the interviewer says kindly continue. i can listen to you. And i continued until the lights came.[30 secs] 2. I was explaining something and then he went on asking how do you do that and tried to enter deep into that. I understood that he has deep knowledge on that topic. Thus, i poiltely told that particular module is outsourced to another company. Thats when he said that "This is where i have spent 15 years of my career." And the interviewer went on explaining. I was listening to him politely and asking him further questions on "oh. i get it now. Nodding as he was explaining for half an hour". he was very happy with my overall interview process.
