Hey dear, nowdays mostly in all college companies do come for their recruitmesnt process for graduates. The procedure for every company is different, some companies have 3 rounds, some have 6. But the basic procedure is first they take a test in which they ask aptitude and analytical reasoning, than comes group discussion and the last comes personal interview and than a list of shortlisted candidates comes.

Generally all the companies that come on campus  take Aptitude test to eliminate student . This is the first round almost every companies do.

Next many companies go for technical /HR interviews but some of the companies go for grip discussion and then go for HR.

Feel free to ask

Good Luck...
