Interns would work 15 hours per week (including some nights and weekends especially during the high school football season), and do a range of things, such as covering games, answering phones, writing notebooks, and working on the web (including social media). The better an intern performs, the more the challenge to the assignments. Exactly how the time is split up each week will vary.
