1st round----general aptitude question like the book of rs aggarwal,arun sharma. But be cautious about time management, because it will be battle of time vs agility.beware of your method solving technique, because it may take toll of your time limit. Finally i want to say...be steady and solve the questions using appropriate method,rather don't stick to 1 question.. afterall only a few can alone solve all the question correctly in stipulated time.
2nd round(HR interview)-----general hr and case solving question will be asked.these are every day life.Be aware to answer them in a compact and correct manner...dont lie at all otherwise it will be a blunder.
