Pluspunten
Working in TV is fun. It's interesting to gain exposure to the customer base, the way the television industry works, etc. There are tons of truly fantastic people. They say you're compensated in "opportunity" which is a way to pay less, but it's also absolutely true - very junior / inexperienced employees are given roles and responsibilities they would otherwise NEVER be given elsewhere. It's a good place to learn - I viewed it as an extended paid internship that gave me fantastic job opportunities elsewhere.
Minpunten
The experience can vary WIDELY depending on the team. I had a great experience with multiple managers spread over several years, but I had friends who experienced unspeakable conditions (30-hour work days regularly, being berated and called "retarded" by their managers, etc.) Ultimately, the infamous culture originates with Charlie (who founded the company and retains complete control) and trickles all the way down. DISH is an extremely difficult place to be a people manager - you're completely stuck owning the unpopular messages of Charlie (no maternity leave; building access badge report time stamps, etc.) People complain about C-Suite level employees not changing these things, but they are powerless- Charlie routinely hires smart executives and then ignores their expertise and does whatever he wants until they get tired of trying and leave. The way to have a good experience here is to find a pocket of great people (and managers) who can insulate you from the culture.
