Pros
It's an iconic company and brand with a great heritage and a bright future. Amazing location in downtown Chicago and just announced moving to a brand new building next year, only two blocks from the current location. It's a company in transition and trying to leap forward from where it has been. Not everything is fixed or will be for a while but if you enjoy transformational work this is the place for you.
Cons
Because it is going through a transformation things are in flux and there is ambiguity at times. There's a culture the company is trying to move away from while keeping the best parts of it and defining a new one. It seems like the organization is really feeling the generational shift of boomers leaving the workforce and millennials entering it. It's not a bad thing, it just feels like you're living through a business school case study at times because there is so much change being driven across all facets of the organization.
