Pros
As a creative, you'll get exposure and the opportunity to learn to design for plenty of different/major platforms and mediums. iHeart can also look great on your resume. The team dynamic and camaraderie can be great and a lot of fun. Work/life balance can't be beat. Project managers are really quite amazing. Annual bonuses can be nice.
Cons
As a creative, the work you're most proud of will likely be neutered by executives who have no vision, or worse, your best work may never see the light of day. Aspirations to produce a better product are often quashed by either deprecated business models or execs protecting their teams' lack of skills. Sometimes, deadlines come hard and fast and with little direction. There's basically no opportunity to grow and learn as a creative. There have been times when teammates have been thrown under the bus to protect higher-ups. The same higher-ups will try to convince you you'll never earn more than the mid-range salary iHeart offers; likewise, the benefits are not even competitive (poor health coverage). Cliques can run rampant within the team. Boardroom presentations can be a very toxic experience.
