It was very casual. They have asked basic questions, mainly on Java and SQL. They have asked behavioral questions too. It should be easy to crack the interview with minimal preparation

I applied through career fair at my university. Got a call to schedule telephonic interview first. Telephonic interview was basic and a few technical java questions were asked. I was called onsite for their college day. Had 4 back to back interviews with a lot of technical questions related to java, sql, networking etc. Had lunch and then was sent back.
