Pros
Very large, private company. There is great career stability and longevity for those who figure out how to play the game of workplace intrigue, or how to never become embroiled in it in the first place. Benefits were decent to fair. A large footprint means there are Chamberlain-owned or operated locations all over the US - which is handy - as they have a penchant for adding and shuttering offices and outposts. As with any company that has a workforce size rivaling that of many small countries, some of the people are wonderful, and others can only have blackmail info in a folder keeping them employed. Chamberlain promotes often, perhaps even primarily from within based on merit, among other things. They are not shy about spending money... Speaking of - compensation is fair for the market you work in and has numerous bonus/goal programs for upper management, exec and C-level employees. tldr: Not bad. Really big. Lots of career options & growth potential. Pays decent. Stable.
Cons
Maybe you haven't seen the show House of Cards, think scandal, intrigue, backroom deals and the like. Most of the senior managers and executive team have risen to their ranks following multi-year and multi-decade careers working for Chamberlain. I spent four years there in a senior role and have never seen the levels of workplace politics, cronyism, step-on-your-face ladder climbing, and other unsavory tactics as I did there. Is this a "Con"? Maybe not. It's commonplace at so many large companies even in the age of Yelp, Glassdoor and Linkedin. If you work at a satellite location i.e. not Elmhurst, IL, your mileage may vary. Corporate process, procedure and structure will likely be implemented remotely and enforced locally. In theory it shouldn't be an issue. In practice, it falls apart. Take operational flexibility away from a remote business unit and you run into stalemate problems that require the brass to fly out and pour over flow charts, process documentation, and contracts. tldr: A lot like Game of Thrones - you good with the sword? Those 10+ year vets are the Frey's.
