The whole process took around a month and I had 2 phone interviews(HR and Manager who are based in US) and one in person interview with the account manager. All the interviews were very customer focused.

Written test was at home, includes basic aptitude and other basic questions. Phone call from HR confirming weather interested in the position or not. Second round Technical round, it was basic too asking about basics of what we know for example C language etc. Third round was Managerial I guess, he asked me to Introduce about me and to explain Final year project and asked me what I know about the company. Make sure to know about the company. Its easy, just be confident.
