They conducted an objective and a coding test with 3 codes. The codes were pretty easy and doable. One code was to sort a link list that is having nodes at odd locations sorted in increasing order and nodes at even positions sorted in decreasing order. The selected candidates were interviewed over three rounds. The three rounds however were not conducted at a similar difficulty level for all the people. They were mostly random with a lot of variation. Overall they asked technical questions on data structures, OS, oops and a few puzzles and brain-teasers.
