Round: Technical Interview
Experience: They may give you a situation and ask you to explain which Software engineering principles will you use. They ask you how will you explain the concept of stacks and queues to a 7 year old, or to a granny, so as to encourage programming(like seriously ? )

General Tips: Nothing as such, since this was my second on-campus placement, I had good experience of interviews.
Keep your fundamentals in all computer science subjects open. Unlike other companies they don't focus much on coding alone. The only other company which also looks at perfection in all computer science aspects is Xerox Research Center India.
