The interview process had a written test, followed by group discussion, technical interview and HR round. Written test had both aptitude and verbal questions to answer conducted by amcat on behalf of NTT Data. Group discussion was about discussing the pros and cons on a given topic among a bunch of 11 people as I remember. Technical round was about writing few basic programs in any programming language of choice and the questions are like write a sorting algorithm, FIFO data structure and few questions to answer orally. HR interview was about myself, my interests, why this company, why did I choose this company for about 15 minutes
