Overall It was a good experience. The first round was online test - consisted of aptitude (Quant + verbal) - 180 questions, 80 minutes. Can be completed with some speedy calculations and thinking.
Interview was pretty chilled out. Nothing much to look for. Just make sure you are ready to shift to any location and any job given. Being truthful, confident and polite should get you in without much trouble. The HR around are friendly and get along very well.
