Very few questions on CV and then they ask me test cases for calculator and then 2 puzzles one is of six rings you have to cut ring in minimum cut's its answer is 2 cut and gave it within minute but then he asked me one puzzle which was very basic but the interviewers confused me with data and I gave wrong answer and I don't know whether he knows the answer or not bt when I give ans of 90k/hr he told its right but the way ur taking is wrong there is logic for that n puzzle was this - if you have to cross 60km distance by car then first you cover 30km distance with a speed of 30k/hr then at how much speed u can cover the remaining distance so the avg speed will become 60k/hrs ans:second speed =60km/hrs. I got this answer when just I reach near by lift but it was to late and for this single puzzle I was not selected for next round. It's my advice to all of you just check out some puzzle on Google like water bucket, rope and bridge, 7 rings, three wrong lables boxes,3 switches, 10 coins. If gone through these puzzles you can definitely crack the interview. All the best all of you.
