TCS Interview Experience

Round 1:

NQT(national qualifier test) consists of two sections i.e., M.C.Q & Programming

M.C.Q consists of general English, Aptitude & general algorithm questions

Programming is mainly concentrated on arrays & structures. My programming is to convert upper to lower case, numbers to $ and lower to upper case in a given string.
Round 2:

After completion of NQT with in a week results are announced and there will be a call for face to face interview. The first round is technical. As I am ECE candidate there are questions on both C and core subjects. The questions I faced:

1. What is a signal
2. How does CPU recognize keys in a keyboard(As my mini is on sequence detection vlsi and major on digital lock system it was an easy question for me)
3. program for prime number
4. program on factorial with recursion
5. They asked me basic questions on linear algebra

Round 3:

As I had cleared Technical round. i have been sent to HR round. in HR round there are basic questions like

1. Can you work in any shift
2. why have you chosen IT sector(as i a ece student, be confident on your answer)
3. why TCS
4. what are latest trends in it sector
5. why haven’t you gone for m.tech(as i got 42 in gate)

there are pretty more questions which i can’t remember.

I went to interview place at 2:00 pm, i have been asked to come in at 4:00, at last i had been out at 5:00 completing both the rounds.45 minutes Technical and 10 minutes HR. Be confident, if you know the answer then answer it. if you think you may know the answer even though answer i confidently. It is my first interview and best i think so.

All the best …
