I applied online. The process took 1+ week. I interviewed at Webaction (Chennai) in Aug 2012
Interview
It contains several rounds of online technical interview questions, where the candidates have to answer them online. If they're satisfied with the answers, they'll ask about UG /PG project and other details or they would ask the candidates for more satisfying answers. Following which there would be an informal telephonic interview which will be followed by 1 or 2 rounds of intensive technical interview which would last for more than 2 hours.
