Interview Preparation Tips

Round: Test
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
College Name: SATHYABAMA UNIVERSITY
Motivation: You will find the it companies mostly head quartered in U.S but this company is in Japan. Plus you have better opportunity and growth compared to other companies cuz its not a bulk recruiter.

Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms.
I usually changed my “Areas of Interest” as per the company profile. For Headstrong I mentioned subjects that dealt with coding and data structure.

Round: Test
Experience: First round was a written test containing 90 aptitude based questions and the time allotted for the same was 90 minutes. Questions were of high difficulty level; most of the questions based on probability, permutation and combination. 40 people were shortlisted out of the 180 applicants.
Duration: 90 minutes
Total Questions: 90

Round: Group Discussion
Experience: In Group Discussion there were 11 people in my group. The topic for the discussion was the “impact of family drama daily soaps (saas bahu serials) on the society”. Almost all of us agreed to the fact that these serials were sending wrong message to the society. They were interested in students who were expressive. 3 people got selected from my group.

Round: Technical Interview
Experience: The first round was a technical interview. Questions related to my family and areas of interest were also asked though. Questions related to C++ were asked and the topic of data structure was their main focus. They asked me questions on linked list and other forms of data structure. Finally they asked few general puzzles too. This interview continued for around 20 minutes.

Round: HR Interview
Experience: In the HR interview, questions were asked on why they should choose me and why I had opted for Headstrong. They also asked which location I would prefer for the job. They wanted someone who would be comfortable with any location whether it be south or north India. This last interview was small and lasted around 5-10 minutes.
Tips: Preparation of puzzles foe the interview would be beneficial.

College Name: IIT ROORKEE
Motivation: Most information regarding the company was obtained by attending the pre placement talk. The company did not check much about our knowledge related to the company but were more concerned with our technical knowledge.
