Hi, aradhna Aptitude tests, Logical Reasoning and little bit of verbal ability test are common in placement rounds. Almost 99% start with these rounds and short list first set of candidates.
If you want to get selected in placement round then I strongly recommend you to practice as many questions as you can. We habitually think that we know how to solve these questions but we fail to realize that speed matters!
In this placement test when 1000 of students like you are competing, companies do not have sufficient time to go through each and every candidates, thus they almost cut down 50-75% of the participants on the basis of aptitude test itself. Those left have to go through another Technical round or GD/PI or something similar sort of round.
