Interviews are terrible predictors of job performance. Consider a rigorous, comprehensive analysis of hundreds of studies of more than 32,000 job applicants over an 85-year period by Frank Schmidt and Jack Hunter. They covered more than 500 different jobs— including salespeople, managers, engineers, teachers, lawyers, accountants, mechanics, reporters, farmers, pharmacists, electricians, and musicians—and compared information gathered about applicants to the objective performance that they achieved in the job. After obtaining basic information about candidates’ abilities, standard interviews only accounted for 8% of the differences in performance and productivity. Think about it this way: imagine that you interviewed 100 candidates, ranked them in order from best to worst, and then measured their actual performance in the job. You’d be lucky if you put more than eight in the right spot.
