This was back in 2017, so the process might have changed since then. There was a coding round with fairly simple questions. (If you're a fresher, I would suggest you join Codechef to practice the format of competitive coding to get an idea of approaching the problems. This should secure you a sizeable advantage over your peers who would not apply this strategy).
The shortlisted folks were called for an interview which comprised of me describing my undergraduate projects (it really helps if you have a strong project where you sincerely contributed) and then moving forward towards basic coding questions. For me, it was fairly easy. Lastly, I was asked about my location preferences and the standard questions, such as my expectations from the company. The whole process took 30 minutes.
