Interview
I appeared for an interview through a campus recruitment drive in May 2010. It has one written test, 2 technical interviews and 1 HR interview.
Written test was focused on core Computer Engineering subjects. Questions were from general aptitude, C output and errors, data structures, basic algorithms, operating systems, few were from databases and computer networks.

Question 1
First round of interview was focused on same areas. Initially they asked me to rate myself in C, C++, data structures out of 10. Questions were not too difficult, some tricky questions were on virtual constructor and destructor in C++.
Second round was totally focused on data structures (arrays, linked list, trees) specially on concepts on binary search tree, AVL trees, B trees. One simple puzzle was also asked.
Finally, HR interview was just for formality.
The interview process includes resume screening, an initial HR call, technical rounds, coding or system design tasks, a managerial interview, and a final HR negotiation before the offer made overall.
There was online Assessment test, once you clear that you will you shortlisted for interviews.
There was 2 Technical Interviews & Final HR Interview and all rounds are elimination rounds
