First round was a aptitude test. 60 questions of Quants, english and logical reasoning was there. They are pretty easy but time limit should be considered. Give as many as correct answers as even 1 question can make difference. Second round was a case study round in which we were given a case study from z s associates itself. There was a lot of pie charts, tables and bar graphs there and we had to answer 6 questions based on 3 different data sets. They are pretty easy if you have command in data interpretation. Here given time is very limited so be quick. Very quick. After that, it was a Technical round in which they will ask the reasons behind your answers of your case study. Several puzzles would be asked, surely one from P&C or Probability. After this, HR round was there. I never cleared technical one, so don't know about this one but i heard that it was a piece of cake.
