I had applied through on campus placements. The first round was logical aptitude test which was easy. They declared the test after 10 mins and I cleared it. I got a call for my first interview after nearly a month where the mostly asked puzzles and about project.During my second interview along with puzzles they also told me to prepare test cases.

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.
