I had 4 rounds, out of which 3 are technical and 1 HR. Overall experience was very good, it was neither too easy nor too tough. They will test your knowledge of the basics not very advanced level questions.

Waste of time. Don't go there they will give you lesser compensation than your current. HR will not respond for 1.5 months in my case since I was expecting 40% hike. They should have informed me before my interview.
