The interviewer was trying to make me stressed by picking one of my strengths and saying that he considers it as my weakness. He was not convinced with whatever I said but in order to overcome above stress be clam and cool. Say what you know without hesitation, be strong, and be yourself. Last but not the least, don't bluff because he will eventually figure it out, even if you bluff say it convincingly.
Tips: Be perfect about what you have written in your CV and just be yourself.
