Paper based Aptitude test followed by a technical test and HR interview. Aptitude test was pretty easy and the technical test was of average difficulty. But I wont recommend the job posting if you're not comfortable with bonds. They ask for a 2 yrs bond.

At buzzle, the first round is aptitude test (pen n paper) which has 50 questions with negative marking scheme. It is easy, but do not try solving whole if not sure about some question, as it is negative marking. Worst part is they collect our phone before getting in.
