There were 4 rounds. First was JAM round. Only fluent english speakers with proper English accent will be considered. There was a grp of 15 from which 1 or 2 were selected. Confidence is the key. Aptitude round was very very easy. Most of the questions were from english itself. The first PI was taken by an HR and final interview was taken by AVP of the company. They were quite friendly. They may try to put you under stress. But to take take stress or not depends totally on you. All the best.
