Tips: There was a single PI round. The panel consisted of 3 members. The HR and resume based questions that are generally asked in an interview are different for every person. So, it's in the hands of the candidate to turn the tide of questions in his favor by ending the answer to the last question on a positive note. The next question that the interviewer asks will be based on the last answered question.You will get the common puzzles on googling. Just write " 25 horses puzzle" and " 100 doors puzzle". They also asked me to form numbers from 1to 15 using only four 4's and any mathematical operator.

Experience: It was not a group discussion to be exact. It was more like an extempore. We were given 2-3 minutes before starting, to think about the topic and then the coordinator would call out a name and that person had to speak for about 2 minutes or so, after which the coordinator would call another name.
Tips: Take a paper with you to write down the points.

Don't deviate from the topic. Just make sure whatever you speak, in favor or against, should make sense.
Do not use any fake accent.
