NTT DATA INTERVIEW EXPERIENCE

NTT DATA PLACEMENT EXPERIENCE:

Hi, I am M. Kalyan, a final year student from VNR VIGNANA JYOTHI INSTITUTE OF ENGINEERING & TECHNOLOGY, Hyderabad. NTT DATA visited our campus on December 17th, 2013. It was a pool drive. We had written test on December 17^th and interviews on December 23^rd.

Written test:

Around 1000+ students have taken written test and around 500+ were shortlisted.  It was an online test conducted by AMCAT, an adaptive test with moderate difficulty level. Once you answer a question you can’t come back.  There was no negative marking.

English-25 Questions, 25 minutes

Synonyms, Antonyms, Spotting error, Sentence completion by choosing appropriate word, two passages were asked.

Quantitative ability-25 Questions, 35 minutes

Questions from Logarithms and powers, number system, time and distance, time and work, averages, percentages, simple and compound interest, permutations and combinations(2-3 questions), probability, boats and streams, profit and loss, trains, ratio and proportion, quadratic equations and problems based on ages were asked.

Logical reasoning-24 Questions, 35 minutes

Questions from coding and decoding concept(2-4 questions), blood relations, logical arrangement of given words, drawing conclusion from a small passage, coded relations, missing number in series, Statements and conclusions, Data sufficiency, Direction sense(2-3 questions), passages on seating arrangements(linear/circular/square/matrix) and deductive logic( like based on some given eligibility conditions we should tell whether a given person is eligible for the job role or not) or some puzzles-these passage models are same as those asked in Bank PO exams.

Computer programming- 25 Questions, 25 minutes

Questions were mostly based on concepts of C language. A short program is given in the form of a pseudo code and we should find the expected output or find out what statement in the given code is wrong. Some questions were from searching and sorting techniques and their space and time complexities. Some questions were from data structures like trees, graphs and linked lists. Two or three questions were from the very basics of Object Oriented Programming (OOP). Being good at basics is enough to clear this section.

Group discussion:

We had group discussion and interviews on December 23^rd. First we were asked to fill a form that asked all the personal information and details from schooling to college, achievements, strengths, weakness, gap in education (Don’t panic if you do have a gap of one year because I had a gap of one year after intermediate and still I was selected) and at the end of the form we were asked to write few words about the most happiest moment in our lives. Then we were divided into batches of 14 members each.  There again in GD room we were given another form where we have to fill our name roll number an college name. At the bottom of the form was the assessment table to be filled by HR. It was:

	Excellent	Good	Satisfactory	Unsatisfactory
Confidence
Communication
Conviction

The topic depends on HR, he is thinking of a topic there itself. Almost all the batches got different topics. The topic we were given was:

Being a developing nation, should India invest in space programs like Chandrayaan and Mars mission?

First he gave a chance for everyone to speak once and then he asked us to discuss. Some opposed while others supported and few spoke about both advantages and disadvantages. You should take your chances and try to be interactive and confident and do not deviate from the topic. One guy spoke about cloud computing which seemed irrelevant to the topic and HR asked him about it at the end. HR asked him to justify his mention of cloud computing in the topic and he was silent. He was rejected!

Total 8 people got selected including me from 14 people. I peeped into the paper while HR was announcing the result, he ticked all the above columns as satisfactory for me.  So it is enough if you satisfy all the three to get selected.

Technical Interview:

He: Tell me about yourself

Me: told

He: Asked me a question from DBMS, which I don’t remember!

Me: I said I don’t know that as I am an ECE student but I assure you that I will definitely learn.

He: Then he asked, if you are from ECE why do wish to join an IT company?

Me: I said in ECE we have both hardware and software subjects, but I am more interested in the software side and coding.

He: What are the software subjects you have?

Me: C language, Java as an elective in 3-2 semester, Computer organization and we use softwares in our lab like Matlab, Masm, Keil which very much involve programming. Matlab is based on c language and we have implemented our project code using Matlab.

He: Write a C program for Fibonacci series.

Me: wrote and explained

He: Ok, tell me about your project.

Me: I explained about the project (mini project) and the algorithm we used very confidently, he asked few questions in between and I clarified.

He: Are you very good at developing algorithms? Ok, develop an algorithm to find the maximum number of queens that can be placed on a chess board so that one can’t kill the other. I want the logic of your approach, I don’t want Program.

Me: Sir I will start with a 4x4 chess board and then extend it. He was watching me solve it on the paper all the while. I got 4 for 4x4, 5 for 5x5 and 6 for 6x6. I got that it’s a pattern and answered him 8 because we use an 8x8 chess board.

He: He gave me a random array of numbers which I don’t remember but the question was

Suppose you have an array 1,3,5,34, 74, 84, 96, 108,356,441,386,502,789,1014

Write a function that takes the above array and a random number as input. If the random number is present in the array then the function should return that number. If the random number is not present then it should return the most nearest numbers either side. Suppose if I enter 4 then function should return 3 and 5. If I enter 14 then it should return 5 only and not 34. Similarly if I enter 889, then function should return 789 only. If I enter 82 then it should return 74 and 84. I assumed 10 as limit on both sides.

Me: Wrote the code and explained the logic. You need to use the concept of pointers and write the code as the function might have to return two values at a time.

He: Is there a better way to do this?

Me: May be sir but this is the first time I came across such a problem.

He: What is a deadlock?

Me: told

He: What are your favourite subjects in your core part.

Me: Digital electronics, Electronic devices and circuits and Analogue communications.

He: Why FM is preferred over AM?

Me: told

He: Rate yourself in quantitative ability on a scale of 10.

Me: 7 or 8. I will go for 7.

He: A shopkeeper has increased the price of a product by 10% and then gave discount of 10%. How much loss or profit does he make with reference to initial price?

Me: Told 1% loss.

He:  Do you have an offer in hand already?

Me: Said no. (But I had an offer from Virtusa Corporation).

He: You may leave.

Me: Thanked him for his time.

I was selected for HR interview

HR Interview:

He: Tell me about yourself.

Me: told

He: Why should we hire you?

Me: told (One of the things I said was I am a quick learner)

He: How can you say that you are a quick learner?

Me: told

He: Tell me about you project.

Me: I explained about the project and he asked questions in between which I clarified.

He: Have you done the project by yourself? You can get the code for this in internet or you might have bought the project.

Me: No sir you won’t get the code simply in internet, you might get the concepts but you never get the code for this, you can cross check and we did the project by ourselves. (It was indeed implemented by us)

He: What was your role in the project?

Me: Sir, we did it together, I have done most of the coding part.

He: Ok can you write the code now?

Me: I said yes and started writing but he stopped me in the middle.

He: Tell me a situation where you have shown the leadership quality.

Me: I have told some situation from our project work.

He: Tell me a stressful situation you had and how you handled it?

Me: Again told some situation from project work.

He: What do you know about NTT Data?

Me: Told what I know.

He: You may leave.

Me: Thanked him for his time.

Rejected people were asked to leave and other people were asked to wait in auditorium. Everyone thought   that people who are asked to wait in auditorium are selected and started making calls to their parents. But sadly not all people who were asked to wait were selected. It could be the most embarrassing moment to the ones who called their parents and said they were selected but finally came to know that they were not selected. So wait until the final results are announced. Final results were announced at 8.30 pm. Total 87 people were selected and I was one among them!
