theodp writes "Out of necessity, reports Slate, tech startups are changing the way workers are screened and hired. Take database technology startup RethinkDB, whose old-school recruiting effort — job boards, external recruiters — yielded hundreds of resumes, dozens of phone screens, and numerous four-hour meetings with viable candidates, but no one who fit their criteria. 'They [recruiters] can't tell the difference between the competent ones and the stars,' complained Y Combinator's Paul Graham. Instead, the RethinkDB founders turned to sites like Github.com and stackoverflow.com to pick up six people (they're still looking), a mix of full-timers and interns, both senior and junior. 'You can see the code being written and how technically accurate they are,' explained RethinkDB's Michael Glukhovsky."
