Info session, written test, group discussion, interview with HR and Tech. medical test. Tech interview very easy. Basic questions about engineering. More detailed questions on your favorite subject. Some questions about what you learnt in summer internships or industrial trainings. Any projects or mini-projects that you have done. A lot of HR interview. Mostly about team work examples, conflict solving examples, leadership example, etc.

Just one round of interview, nothing technical was asked. they just wanted to know if you really want to join HMSI and know what they do. This was from campus hiring and my institute was good enough that they knew they don't need to worry about the technicals.
