First round guy was concentrating on the logic and asked some great questions and was polite in taking the interview.
Second round guy was sitting just to contradict you. From the first minute he started contradicting. He thinks he knows everything and you should know all the terms that he knows. No matter how much you know the login and concepts, you need to know the terms which he knows. Company should know whom to give responsibility of taking interview because after today i have lost faith in mmt.
