Summer intern programs are a great way to get quality work for a good bargain (see our post about the new DOL regulations on paying interns here). It's also an opportunity to hone your management skills, methods of providing constructive counseling, and test-driving some of your less experienced managers in roles of responsibility. Yes, for all intents and purposes, your summer intern program can be your managerial guinea pig.
When you're sending out calendar invites for the summer interns' exit interviews, don't forget to schedule a time with your own people about the experience. This an opportunity to improve the summer intern experience for the next class, and this is also an opportunity to develop, applaud and, perhaps, correct supervisory tendencies of your employees. You can also use the post-intern feedback to see if having an intern program is right for your company. Just like evaluations, one size does not fit all, and you don't have to do it because everyone else is.
