NTT DATA Software Engineer interview questions

GD,Technical and managerial interviews. GD: Too easy,just analyses your listening skills and the way you summarizes things not that you shouldnt speak,you should have your own views. technical:too easy to say.i am frm electronics bckgrnd,i only knw C progrming.i answered every question.the technical interviewer was so friendly.my interview went so cool.he was totally impressed,evry 1 was informed late bur for me he just said "Go HR will be waiting for u",i asked him"sir?",to ensure what i heard is right?though i am not going to join anyways,the interviewer made me feel good about myself. HR/managerial interview:it was like another technical round.asked about my projects.and being from electronics y IT? i some how managed.here the environment is not so friendly like before. Process:initially,300-330 members GD:batches upto 19,5 to 6 from each batch after Technical around 60-70 members after mangerial 30-40 i guess.

It has three rounds. !) Written(basic aptitude) 2)Technical Interview 3) HR interview The written test consisted of basic aptitude and English paper. It was conducted by Aspiring Minds The Technical interview was very interesting. I am a student with electronics background and I was totally asked questions from my subjects and my area of interest few of those questions were 1)Can we replace a 16 bit microprocessor with a 32 bit microprocessor My answer: When we use a microprocessor its not just the processor we use, we generally use a family of processors and any microprocessor does not have a memory so we need to interface a memory to it, so it is not the number of bits always it is also the interfacing we need to take care of and each microprocessor has a particular working frequency and we need to take care of that also 2) Design an AND gate with an OR gate My answer: we cannot design an AND gate with an OR gate. A gate has to have some properties for it to be used to derive other gates and NAND and NOR gates have those properties therefore we use them as universal gates but OR does not, we cannot derive 3)What is and encoder and a decoder My answer: MUX with multiple outputs is an encored, the selection lines in the MUX are the outputs in an encoder and it is used to convert the data from one coding system to another 4) Describe the process of communication My answer: Totally described how it takes place , from speech signal to sound signal, the types of tranmisson, types of modulation, networking etc. 5) What is the difference between printf and sprintf My answer: I don't know the aswer 6) Write a C program which involves an arithmetic operation, pointer and printing statement My answer: Wrote Fibonacci series program 7) In an array why does the first element always start with a[0] My answer: In a flip flop the least value that can be stored is 0 and the highest value is 1, and the data in the computer is stored in flip flops, what ever the size may be we use flip flops to store the data, so the label given to the first flip flop where the first data is stored is 0 therefore we use a[0] insted of a[1] 8) How can you justify a person with ECE background can fit into IT My answer: The answer is obvious in our discussion only sir, if I did not know what a flip flop is and how it works I can never answer or understand why a[0] is there instead of a[1] He liked the above answer and sent me to the next round HR round My HR round was just like another technical round In TR i was totally asked about electronics and in HR I was questioned totally about communications, how it happens, why, its advantages and dis advantages. It was like another technical round After the HR round the results were declared and I was selected for the job
