Easy questions, no negative marking, comprised of english , aptitude and logical reasoning questions. Second round was Technical . Being a student of Electronics and telecommunication background I was needed to brush up my Core knowledge. Questions were asked from mobile communication subject like drawing GSM network. Other questions were related to the training and internship that i did . This round was a major elimination round. Most of the people were removed in this round. For CS/IT students technical round was more of checking on their logical ability. Last round was HR , it comprised of personal behavioral questions.
