If you work in the world of recruiting, you’re most likely familiar with an interview technique known as “Good Cop/Bad Cop.” The Good Cop explains the benefits of the job and focuses on the more expected, less intimidating questions: Tell me about yourself; what are your strengths? The Bad Cop asks the tough questions: Do you think you’ll be challenged in this role? This job has a lot of travel – how will that work with your home life? 

The goal of Good Cop/Bad Cop, in theory, is to ensure that the candidate fully understands the job, particularly its challenging aspects. When done correctly, Good Cop/Bad Cop interviewing weeds out weak candidates and avoids any confusion around the role. However, if executed poorly, this technique not only scares off top talent, but also damages your brand.
