The aptitude test is simple. Try to score as much as possible. It counts for quite a lot. Questions in the technical interview will mostly be related to practical issues in computers. The subjects of interest in your resume will be considered; so make sure you're up to the mark in those subjects.

About 120 applied (Computer Science and Electronics & Comm. students). 9 were selected.

What worked for me was confidence, good communication skills and more or less sound technical (practical over theoretical) knowledge and an excellent score on the aptitude test (49/50).
