Let's face it. Cross-table interviews have always been the LEAST effective way to screen job applicants. They know what you will ask and you know what they will say in response. You want to watch them in motion and in the environment in which they would be working. When you interview applicants while touring the facility, all those rehearsed answers go out the window. Then you'll get candid answers. Why? Because most people can't walk and lie at the same time. You want to see how they think on their feet.
Follow the seven steps in this guide and watch how your screening accuracy goes up dramatically. Then pass this guide around to your colleagues. They can use the help as well.
