I was referred by a friend working there. Had an initial technical screening where I was asked to write code for a LinkedList based problem. Later, I was invited for a series of onsite interviews at their Hyderabad campus. I had two rounds of interview at onsite. In each round, interviewer asked me two coding problems. The problems weren't too difficult as such, but very quite tricky. It was quite possible to miss out a corner case (which I did). Unfortunately, since I didn't perform well in one coding problem, they decided not to move ahead.
