Do you want to hire someone who is always finding faster ways to complete tasks? Someone who works efficiently? Someone who is current with technology?
You want to avoid speaking with desperate people who have few career options. Instead, you prefer interviewing candidates with the kinds of skills that most employer would welcome, right?
You don't want people who use their work computer to conduct a job search. You want someone more discreet, right?
Congratulations. You just described the kind of person who is probably using their mobile phone to be alerted to job opportunities. And if your recruiting process is not mobile-friendly, you have a 40% chance of never seeing their resume.
