1. Revolving door: At a little over a year and a half, I was one of the most senior employees in my group. Management doesn't seem to really care that employees are thinking of leaving, but rather would just hire somebody new for cheaper.
2. Pay: You're definitely going to get underpaid. They claim they do market studies every so often, but I haven't ever seen it lead to substantive pay increases.
3. Management culture - Management is definitely stuck in the past days of working harder not smarter. You'll be hounded if you do anything less than 40+ hours (40 will not be enough), they monitor and make sure you keep their "core hours", and often throw tasks at you that are either busy work or not even relevant to a good business decision.
4. Company future: Dish Network is in decline, and anybody who denies it is kidding themselves. They claim to have a great plan going forward, but rarely seem to take steps to actually execute on it, and when they do, it's done incompetently because management doesn't really seek the advice of their employees, they just make gut decisions without any backing in data.
5. Equipment/Culture: You'll be lucky if given a laptop (only given to their more senior analysts and up), and you don't have the option of working from home. The management insists because they're trying to build something together as a team and want the team together, but it's a lame excuse for not really adapting their outdated culture to modern times. All the tech you work on will be at least 10 years out of date and run incredibly slowly.
