I applied to TCS through my campus placement cell. It began by first registering to TCS nextstep web portal few days before TCS was to visit campus. The entire hiring process was a day long. First, we had to give an online aptitude test which had three sections- Quantitative(Few simple math questions),Verbal(Some fill in the blanks and a passage) and Writing Skills(Writing a formal letter on the topic). The people with their engineering aggregate more than 70% were exempted from Quantitative and Verbal and had to appear only for Writing skills section. Shortlisted students had to appear for the next two rounds of interview-Technical and HR. 1)Technical Interview-It was mainly based on algorithms,datastructures, operating systems, databases and programming language(any which you know).Not much grilling in the interview.It was pretty straight forward.Not very difficult.Expect many questions on your resume. 2)HR interview- This was only for name sake and simplest of all.They ask about your family background, your interests and your availability to travel throughout different TCS locations.They tell about their company policies and ask for your agreement on them.(They favour people who are willing to travel as TCS is very large and located at different places). If you are selected ,they give you offer letters in few days with all the job description and pay packages.You need to accept them within 7 days. After accepting you need to complete(as per your convenience) an pre-Initial Learning Program(ILP) course called 'ASPIRE' before they provide a joining letter.

It started of easy with some questions about my projects and then to writing the code of my projects. knowing your basics of things that you put on your resume would help so much.
