TCS Technical interview last nearly an hour.
They first asked me to introduce myself. (Just say what are your areas of interest and what are the projects you done)
In this round, they see our Mark list also, so be sure to answer the question "why you got low marks in this subject"
Then they tested "How for I am good at logic".
For that they gave me a number and asked me to find is that number Armstrong number of not. (Armstrong Number is 153 = 1^3 + 5^3 + 3^3)
Logic : first separate the digit and store it in an array, by dividing the number repeatedly by 10 and storing the number in an array. Then sum the array, with cubing each element and check whether it is the same number given
If you do the program correctly, you are qualified for next round
They also test our Maths and Science knowledge, so just have basic knowledge about them
Following questions were asked in Maths
(Rank of the matrix, aigen values, Mean, Standard Deviation, Poisson process, Fourier series)
Following questions asked on Science
(Ohms law, Diff between Generator and Motor, Diodes)
Fact : They don't expect us to be good in maths and science, but atlest we should be in average
Finally they asked me about Positive and negative Character, and be truth ful.
That's it.. You can clear technical round very easily
