It was a on campus placement. The process was divided as: 1. GD :They made group of roughly 8 people. 2 -3 people were eliminated in each group.(all were selected in some). GD was very easy to crack. You just need to make some points regarding the issue and speak about them thoroughly. 2. Technical Round: It lasted for around 20 minutes. Questions were related to C++ and java (pointers and OOPS related) . The interviewer also asked few puzzles (typical questions) and quant related questions. 3. Managerial/HR: This was more of a formality. The interviewer was very polite and went through some very expected questions like why NTT.
