Hiring the wrong person can cost your business plenty, but an internship program can help to cut down on these sorts of mistakes, Pamela Hawley writes. An internship "allows both parties to see if the skills fit, and if the values fit. Someone could be talented yet not enjoy our culture, or we might not feel alignment," she writes. If there is a good fit, an intern can eventually become an employee. If not, you just say goodbye when the internship ends.
