If you’re weighing whether to hire a promising job applicant, ask them to visit one of your branch offices, stores or plants and look around. (If your firm has a Web site, that counts too!) Tell them you’d like to hear their observations. What do they like and not like? What would they improve? Is there anything that they think your company is overlooking? The benefit of this job-interviewing exercise is twofold. First, you can assess how well the candidate completes a task (in terms of following directions, meeting a deadline, etc.). You can also evaluate the individual’s intelligence and common sense based on the quality of their observations.
