Interviewing Job Candidates is Often Unhelpful
Those who insist on interviewing candidates often make worse decisions. Shane Parrish at The Knowledge Project explains:
In the end, participants who were able to interview the students made worse predictions than those who only had access to biographical information. Why? Because the interviews introduced too much noise. They distracted participants with irrelevant information, making them forget the most significant predictive factor: past GPA. Of course, we do not have clear metrics like GPA for jobs. But this study indicates that interviews do not automatically lead to better judgments about a person.
