There were totally 3 rounds and they check the verbal and communication skills of the candidate and asked to speak about anything they like the most. then they gave a topic and asked to speak about that topic for a minute. it was a 1 day process. And the interview was quite difficult when compared to other companies. They also asked questions about computer skills and some questions relating to troubleshooting of devices. 1. JAM 2.
