Hello Shilpa,
Campus Recruitment Drive means the colleges invite the IT or Non-IT companies to visit their colleges for the purposes of recruitment. The employer company would visit colleges to select the potential employees. Each one of these companies would have its own selection creteria like the students should have continuously 65% and above and they should have excellent communication skills (both oral and written) etc. They will conduct first, written tests, then, group discussions and finally the one to one interviews. This is the process of recruitment.
The other one is how to get these employer companies to our colleges? The college Placement Officer would do this job. He will visit these companies in person, and try to convince the HR guys of these companies about his college. The interesting point to the HR would be the selection ratio. If he gets one out of every twenty students, it is OK. In support of this trend, the Placement Officer would show his college website, or brochure. It should show the kind of infrastructure facilities, the labs, the training departments, the kind of activities, the potential strength of the students with high % and their achievements etc. If the HR believes that it is worth visiting the college, then they plan the visit. The college would arrange and facilitate their visit and extend its hospitality for the recruitment team. This is broadly the recruitment process. If you have any more clarifications, please write to mek. Thanks and regards,
