It consists of three rounds 1.Aptitude 2.Technical Interview 3.HR Interview It is a easy process. All the questions were basic in aptitude, no need for extra preparation for aptitude. Technical Interview was also relatively easy when compared to other interview processes I have faced. Only fundamentals were asked for interviews. In HR round usual and often asked question were asked like, Tell me about yourself?, Tell me some strengths?, Why we should hire you?, Why do you want to try TCS? IT is a very easy interview to clear.
