Pros
A lot of the systems rely on pretty tight and well-documented SOP's. If you're newer to office work, you'll probably get a thorough crash course in time management, organization, etc, that will skill you up for future roles. The Oak Brook office has some nice amenities, including a gym.
Cons
There's pretty persistent word that most decisions, down to small ones like raises or open roles, go to the very top of the company. Whether or not this is totally true, a lot of these decisions are made with bottom line in mind and little consideration for employees. This causes tons of issues. One key area where you notice this is employee retention, with minimal efforts to reward performers and few attempts at keeping people to develop and grow with. Plenty of departments feel like revolving doors, and at times the communication between various teams can feel adversarial (sometimes this seems encouraged) when there aren't longer-standing relationships. The lack of experience and know-how makes more work for everyone and contributes to a low morale, which in turn leads to feedback loop for turnover. You'll find some people that are pretty enthusiastic about the company still. Most of them are grandfathered in from a previous era of Hub and even then plenty of those types have been unceremoniously axed as the leadership has been handed down to the new generation. By and large, this is a company is reliant on employees being blindly loyal or otherwise complacent in their work situation. Not a recipe for success.
