It had three rounds. The first one was an online aptitude test. I was attending the interview in my college. Unfortunately, I couldn't make it to the second round. The test had 30 questions which was divided into 4 sections. Each section had a cut off rate i.e. in each section atleast 60% of the questions should be attempted and all the attempted questions should be correct. Also the test had negative marking. All these factors are very tough for a student appearing for a campus placement for the first time. If you're attending an interview, make sure you're well prepared for aptitude.
