Infosys interviews are highly process oriented and standard technical and personal round combinations. My experience is now 6 years old, so I am not updated with the current interview routines and structures.
I applied through college or university. The process took 1 day. I interviewed at Infosys (Mangalore) in Jan 2010

Had a written round, after which a truck load of people were selected for the HR round. After that around mid-night results were announced. Joining date was after 6 months. In between that they sent mail to which one had to send documents.
