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.

Phone interview, then into a in person interview. It's all really simple, just know what job you're applying for, and make sure you know about it. Make sure you remember stuff from your previous job, skills, examples of things you did, etc.
