The first staffing firm I worked in was a satellite office in Los Angeles. We had a Monster and a Dice account, but our primary files was a stack of resumes about 6 feet tall that came from a pair of files in the corner. We would take the files, call people, and "update their resume," while putting them into the computer.
Good times. And as I progressed in the organization, I would always start my recruiters out on those paper files - learning to pick up the phone, dial, ask questions, and enter information into the recruiter. Those that did well in that first week excelled. Those who struggled with just that simple task, never got it and quickly moved on.
Today we have the fancy applicant tracking systems that are supposed to solve all our problems, but I still maintain that working with paper files the first week or two is the key to good training, both for the phone and for entering data into the computer.
Yes, I do a lot of training and talking abotu social media, but the secrets of my recruiting success has always been more phone calls than google searches or board resumes. And while I use social media to prospect these days, I use the phone to close the deal.
