Pros
ESPN is a big company that is well-known, so you can be proud when you say you work there. The job security is very good, as you can't get fired for poor job performance. The benefits package is also excellent, which is no small thing nowadays.
Cons
ESPN knows it's big, and knows everyone who hasn't worked there wants to work there, so they treat their employees like garbage. They don't care about paying competitive rates because they can just get someone else in to do the same job. Moving up is very difficult, as they are reluctant to promote anyone due to the required bump in salary. Also, become promotions are rare, people are reluctant to share information to better the product as a whole, because someone else will get credit for it and steal their desired job.
