Round 1: The first round was TCS national qualifier which was test held across India. There were 4 sections in the test. In the first, there were fill in the blanks English questions. They are very easy. In the second section, there were aptitude questions basic as well as advance. The third section had technical questions. Most of them were related to C language and a few related to data structures. This section also contains basic as well as advance section. The last section was the coding round. I got a question on Series. The coding questions of other slots were like, find the nth element in a given string or find the nth number in fibonacci series, or string related questions. After that those who qualify this round, got mail from TCS, that they got shortlisted and gear up for 2nd round.
2nd Round: We have to go to the center, provided by TCS. There first of we have Technical round.There are many panels like panel of 1 guy or 2 guy.
