I applied in this company via friends referral. Interview started with Aptitude test, followed by technical interview and lastly got to know I was selected and an offer letter would be mailed to my email ID.

Simple grammatical and mathematical questions. Next round was HR round, which was pretty smooth. Last round would be to test their actual games. I tested DiRT 4, and had to write down few bugs. Also, they'll give a list as to what y'all check, just remember not to tick everything, as it makes them think more skeptical about you.
