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.
