One written test concentrating on OOPs. Included aptitude too but did not give much weight-age to it. Followed by one technical interview and one HR. Technical focussed on DS and OOPs and a bit OS ad asked some 3-4 puzzles too. PUzzles were all those standard torch light and water jug problems. Data Structures included about how will you design one dictionary or do yuo know about D-Queus. Asked about my management skills if I have done anything in that... Was able to sight 2-3 points in that
