Invite the candidate and his buddies to your next company event. Start having them. Lots of them. And it's how you identify more of the kinds of people you want to hire before you need to hire them . Talk, talk, talk The single biggest mistake to make in an interview is to spend it all talking.
Talk is cheap, and it's a waste of time by itself.
Instead, take the candidate on the company tour. Introduce him to other employees. Explain how the marketing manager does his job, and let the candidate chat with him. Tour the manufacturing floor and let the candidate demonstrate how he would inspect the production line. Show him the tools he'll be using if he's hired.
