There were three rounds.
First is technical written where you need to write some simple as well as tricky programs. Some simple database related problems were also there.
If you are through they call for f2f interview. Again two interviews were there. All they focus is on your understanding about current project as well as basic concepts of Java. They ddnt ask about spring that much. But again your basic understanding should be good. Same is the case with database, struts, web services etc.
If you clear both, next is hr round.
