NTT DATA Developer interview questions

It was an on-campus interview. As i was from Bio-medical background, the interviewer questioned me regarding the basics of my subjects. Then I was asked to solve a puzzle. Then few questions about the basics of computer science. I think they wanted to know whether I was good at what i did previously. There were three rounds: 1. Aptitude 2. Group Discussion 3. Technical 4. HR

I applied through College. AMCAT conducted written test in moderate level which consists of Usual AMCAT pattern. But i lost in Written round itself. Results were announced after two weeks.
