Thank you for your comment! Sure this can be an online and offline solution where the students get to see different jobs online and sign up. While online, students can explore a virtual tour of possible job options and before they decide the student can have a short description or course guide of the job online.Maybe while offline they can talk to teachers or counselors about the program and get general information of the work field. It's hard to incentivise this program but I would say that the working people can educate possible workers for that field and get a feeling of accomplishment(incentive of pride and feel good about it). Mentoring can be difficult, some jobs are just so busy. I recommend that students first need to understand the work, and then work on a relationship with a trusted understanding mentor.
Of course this could be applied in universities! Maybe the idea can be applied in community colleges first to test the waters and see if it suits the interests of the students. If they want to do this during their vacation time that's fine, there can be multiple representatives that day for more efficiency. If the university has a undecided programme, I think they can apply this very well with it. The university can partner up with businesses or jobs that are finding more employees, the more businesses partner up the more potential for millennials to find their futures.
