It's a good question. We do establish these inventories, but unfortunately we don't have enough touch points of communication with candidates. We should be having regular feedback. In fact, in some cases, we can set that up without necessarily having individuals make a call. An example would be sending an email to all students to ask them to please update their profile on our student website and to please indicate if they're still interested in student employment.
Little things like that nudge people. It helps, because then the inventory is fresher for managers who make the calls when we refer candidates. If we refer 10 people and they get 10 responses of “I'm not interested,” “I've changed my phone number,” or “I'm working for Google. Thank you, I'm not interested,” that frustrates managers. If, however, they get eight out of 10 who are interested in an interview and potentially in being considered, then that makes for an inventory that people will use a lot more.
