Interview Preparation Tips
Experience: Time management is very important to clear the aptitude test. Besides this a lot of practice is also very important. This round is the major filteration round. Though each round is a major filteration round cuz NTT DATA is not a bulk recruiter like cts, infy etc. Almost 2-3 thousand students were there for this round from 6 different colleges and only 100 of them were selected.
Tips: Its better to start with the preparation from before and do consider the previous year placement papers available at indiabix. You can practice more n more. Apart from this you can go through the r.s aggarwal aptitude book also.
Round: Group Discussion
Experience: There were many panels and each panel had 10-12 students. The H.r first decided some other topic but when he asked wether everybody is aware of the topic ..there were few who didn't know about it. .so he picked up another topic. Fortunately he asked me to start with the discussion. Always try to be the one to break the ice.
Tips: The only key to crack this round is that yku should talk. You should definitely not confuse gd with debate. You should not argue or by any chance shouldn't sound arrogant.
Round: Technical Interview
Experience: They will definitely ask about your project so be thorough with that. Ntt data is a Japanese company . Though this is IT but it will ask from the subject of your own choice from people those who have a non IT background. After you get shortlisted in d gd they will give you a form to fill. Do fill that form without fail. If it is blank then even if u go to the hr round he will reject you.
Tips: Just be confident and always smile. Be careful on what you write in your resume cuz they can ask about anything based on your resume.
Round: HR Interview
Experience: This round was a cake walk. Just be confident and updated about the company. Do ask him a question if he asks you to do that.but make sure it shouldn't be vague or out of the picture.
Tips: Keep smiling and don't get nervous. If they ask you about location preferences, dun get firm at one place.try to be flexible.
General Tips: Donot loose hope at any cost. You never know when your moment is going to arrive. Do practice the aptitude as much as you can. Finally NTT DATA selected only 50 overall in wch 11 were from my college n i was lucky to be one of them. the offer letter was issued the same day and we were all venerated. Its just a game of confidence. All the best
Skill Tips: Try to add some co curricular activities and justify your role.
Skills: communication, technical knowledge, management skills, leadership
