At the recent NACE 2011 conference, attendees heard over and over again that the 40- or 50-something recruiter doesn't connect to students in the same way that a recent grad who works at the company can. The younger recruiters are seen more as "peers" who can better address the process of looking for and interviewing for a job these days.
I am not discounting the importance of a senior member of your staff being involved with campus recruiting. Their years of wisdom and knowledge of the company are key to sharing stories and showing stability within your organization. What I am saying is be sure to bring along your company's 20-something recruiter who can cue into the little nuances of today's college student. It does make a difference to the students and will help your company stand out at the career fairs you are putting so much money and time into. Try it, and let us know how it goes.
