1. An astonishing bait and switch from the interview process to being brought on board. You will end up being hired and then not be allowed to do your job.
2. There are a lot of threatened people here who fear the competence of others, which means you've got teams of incompetent people who are not held accountable for their own performance.
3. You'll literally be told to be mediocre and to slow down your motivation to do your job well.
4. You'll be discouraged from doing your best or exploring and presenting other ways to improve processes.
5. You will not be allowed to interface with your cross functional colleagues around the nation without "permission" -- which really means that you are not trusted to do your job or to be an adult. Managers and directors here want to claim your successes no matter how small, and if they can't they'll get rid of you.
6. You'll quickly tire of the politics that don't yield anything good or useful. You may even be told directly that you need to make your ideas seem like they are the ideas of others less competent than you-- instead of being supported by your leader.
7. Many often end up reporting into an incompetent, so-called managers who lack professionalism. Some are even allowed to exercise their personal biases, dislikes, and jealousy against you.
8. If you try to do your best, you'll literally be told NOT to, and you may be hated for being professional and articulate.
9. If you come from Fortune 500 companies, are at the top of your game and try to share best practices that can benefit the business, you'll be told "we've never had anyone like you." You'll be told "we move slower than what you're used to." But you'll never be told that you can actually help improve things because you won't be allowed to do so.
10. The marketing and sales departments have either lost or ousted highly competent people, but the common denominators in those situations are are a particular manager and director.
11. In some departments, there are so-called managers that do not know anything (which would not be so bad if they knew how to lead and manage people and processes), yet they are allowed to remain and stifle others that are exceptionally talented and competent.
12. Managers and directors are not hired due to their skills and knowledge -- they are hired because they are friends and family of others entrenched in the organization at higher levels, or because the region fears a discrimination lawsuit if they try to rid themselves of incompetent people who have been hanging on and collecting a paycheck with a sense of entitlement.
