Pros
None. All of the free food in the world isn't worth it. As to the hours, myself and the people I worked with were all putting in 50-60 hour weeks, with no flex time or any thanks for it.
Cons
Unethical and extremely poor leadership at the highest levels. What is acceptable for one team is taboo for another. The board should overhaul the entire executive tier, starting with the CEO. He can't be bothered to come to work in the summers anyway. He fires people without cause, relying on fact that he can ,because this is Illinois, and he doesn't need a reason. The CFO is also a horrible human being who needs to be knocked down a few pegs. Between the two of them, I've never been treated so poorly. Do not take a role here, on any level. You will regret it. Don't drink the CEO's kool aid.
