Pros
Discovery is a great brand to have on one's resume and the colleagues were some of the best. With the exception of the support functions, the staff at Discovery are bright and vibrant, and it's easy to make friends who conduct themselves with sincerity both professionally and socially.
Cons
If you enter Discovery on a contract, don't expect to ever be converted to a permanent position. The divide between management and executives is vast and self-perpetuating. Everyone below the position of manager is deemed expendable and this is evident when you compare the turnover rate between management and executives. Promises of career development and salary review (because annual raises are a joke) are simply tools used by management to obtain greater mileage from executives, so be sure to only stay long enough for your own growth because you need to implicitly understand that the company will show no loyalty toward you.
