When young interns & graduates are disengaged, they become brand detractors instead of ambassadors.
Running a successful program becomes complicated because of all the little admin tasks, like scheduling training, reminders, invitations, etc.
Internship & graduate programs need lots of internal resources, and this limits the number of interns you can take.
Mentors face a triple challenge during internship programs: they need to manage the experience, deliver training and stay on top of they own workload.
When you reach the end of the program, knowing who is a good fit and who is a bad fit for the company makes the difference between success and failure.
Let's face it, your mentors are great at their jobs, but their job is not to be an expert instructional designer, and because of that content sometimes is too static and overwhelming.
