Almost every MNC companies consist of written Test as their first round of the Interview process. The written Test can be conducted in two ways. One is by online Test & another is by using pen and paper.
          And the questions for the written Test will be prepared from many topics & it is normally categorized into Aptitude,Quantitative, Logical &Reasoning. Some of the companies also include some technical related questions in the first round.
(Important)
          You will be eliminated if you fail to clear the first round. And it is quite difficult to clear the first round without any regular preparation.
          So, I personally request you to focus well in the first round preparation.
