Round: Test
Experience: There were totally 8 sections to the test. But they could be broadly put under 4 categories. Firstly all questions were compulsory to attempt and there was no negative marking. Aptitude: Basic quantitative math questions were asked. There was one simple programming question where one could code in C/Java in your local IDE and upload the code file. It was a DO or DIE question, either you get the question and proceed to the next questions of the test or the test gets stopped if the code is not successfully compiled within 5 attempts. This programming question, as was told was an important criteria to filter out candidates for the next round. There was a descriptive question asking about a recent team project done.
