NTT DATA Developer interview questions

It is an on campus interview. I cleared all rounds in the interview process, except the last HR round. I feel comfortable in the technical round. While coming to the HR round, he asked me some random questions. Even-though I answered everything he did not select me in the hiring process

Interview is done with 3 stages, 1. Technical interview: Average questions, but you have to remember few key questions even though you are very good at work 2. Management interview: Tried to understand the attitude to wards long term association. 3. Client interview: Tried to understand if the resource is useful for the project.
