How one should approach good companies to visit college campus for campus placements

All said and done. Contacts work.

If you are really looking forward to bringing in the Companies for Campus, have either of two, contacts, or an impressive presentation. 

To work towards it, know some basics:

: Have a Very Impressive Profile of Currently-to-be-recruited students with you. If Possible have one student working as a Placement Co-ordination Head(for the batch). Train him to talk accordingly, and do all initial discussions. Some Companies take it positively.

: HR like being entertained financially, you should be clever with the tactic to influence him/her, if so, they will sure consider your side. 

: Never expect the first of second meeting with a college to close a deal for Campus recruitment. Expect at least three primary intro visits and three confirmation visits (prepare for it at least). 

: Start the activities for Placement Alliances six months prior to the dates of expected placement. Keeps your options open, just in case....

: Try telling the students the rosy part of hard-work they need to do, in a job. Many students are told, jobs are tedious and stress giving. That makes them negative about whatever you give even before the start.

First build a good contact with the company & show them the performance of your college. Moreover...report on performance of college students can also support the cause. The placement officer should handle the situation tactfully as no company wants students who will fool around.
