(I was probably the only one who had 3 tech rounds. I think I performed pretty well in all of those rounds. Some people had just 1 "almost" tech round with hardly any tech questions popped. Some had 2 tech rounds. However even after 3 super-awesome tech rounds and a cool aptitude test I didn't get selected.) What my fellow classmates(some with 1-2 "tech"/HR rounds) were asked: * Did you have lunch?(got selected) * Are you gonna interview at other companies after this?(said a yes! - got selected) MORAL OF THE STORY : THEY SEEM ALLERGIC TO HIRING SMART PEOPLE !
