Pluspunten
iHeartMedia does afford you a lot of freedom to dabble in numerous aspects of entertainment and marketing. Certainly their focus is on their radio products, but there are plenty of roles available in IT, engineering, social media, project management, promotions and sales to be had. If you're self-driven, and don't mind working yourself ragged while wearing a lot of hats, you could take away a lot of great experience in a variety of fields.
Minpunten
Very little recognition for your work, especially for tasks that don't show up on reports to Corp. Promotions are rare, and there is no growth plan in place to allow for individuals in local markets to advance to the corp. level. So many roles have been cut and responsibilities shifted to other departments that the workload is insane - 50-60 hour weeks are the norm. The company is heavily in debt, so most business decisions center around cutting staff, cutting budgets, or convincing individuals to do the job of 6 people. Much of the stability of your market hinges on the unmotivated and out-of-touch sales staff - if you're in a support role in another department, you could easily lose your job if your sales staff doesn't hit their numbers.
