Dennis Smith, CEO of WirelessJobs.com, discusses techniques for effective recruiting as a "caveman recruiter" in the modern age of social media and technology. Some key points include mastering communication skills through compelling voicemails and conversations, following up persistently with candidates, appealing to their interests and ego, and presenting opportunities as life-changing rather than just another job. The overall message is that recruiters can compete for candidates' attention through passionate and personal outreach even in a busy, digital world.
