I had applied through college.I was interviewed at my college by the company.There were three rounds. First round was basic Aptitude(with Negative Marking) MCQ and Essay Writing. Next round was Techical cum HR round.

2 rounds both are technical and the hr rounds which is easy. both technical round is average to answer. but sometimes it depends on the client like client will take 1-2 rounds base on your knowledge so you have to be preapre for whatever you are going for the interview as software developer
