Round: Technical + HR Interview
Experience: After entering the interview room, the first question asked to me was "Walk me through your CV ".After that, I was asked some puzzle questions, one math question and a case study question which was bit difficult. 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.
