It contain 2 rounds:

1. Aptitude test
2. Technical test + eassy writing

After written test, there is a communication round (not GD). In this round you have to speak on a topic given by judges (members of recruitment team).

They asked me questions related to JAVA, C, C++ & my final year project.
In JAVA, questions about multithreading, classes etc. (very basic questions).
In C, questions like "predict the output" (for this, i refer "Exploring C by yashwant kanetkar").
Apart from this, she (My interviewer was a lady) asked me general questions like latest launched gadget, question about xbox & PS3 (this question is related to my hobby of playing PC games).
In short, it was not tough and i think that they checked only the basics.

It was amazing & my interviewer (again a lady) was very supportive. The first question was "Introduce Urself?". Please always prepare urself for this question, it's commonly asked.
After that she asked questions about my hobbies, my future planning, my strengths & weaknesses.
She also want to know that how much i knew about the company.
Please be confident, clear & fluent while speaking. In CSC, they mainly focus on fluent & clear English.
ALL THE BEST to all of you.

For written exam of CSC, please,.. please visit "www.freshersworld.com" for placement papers.
And please sincerely do all placement papers of CSC available on "www.freshersworld.com", specially technical papers.

I just want to say that be confident, be optimistic and never loose hope. CSC was my 13th company and this time i am in.
For written exams, i think "R.S Aggarwal" (for aptitude) is enough. "Exploring C" by Yashavant Kanetkar is best for the preparation of C related questions.
Apart from this, please improve your English also by reading newspaper daily, watch English movies and read "word power made easy", it's really a good book to improve vocabulary.
If you have any query, feel free to contact to me. My ID is-"rahultyagi.mrt@gmail.com"
