Many people in managerial roles don’t like to practice what Koch likes to preach. When you join the company or are being recruited, you are told they want to make sure you are fulfilled and that the company will help you get to where you want to be, but that’s purely a marketing tactic. I know so many people at Koch that were unable to transfer to new roles or between Koch companies because someone in upper management would not allow it. There is a lot of opportunity at Koch...but whether your leadership will encourage and spur you on towards those opportunities is kind of a gamble.
On another note, the company culture was at an all-time low when I left. Much of this boils down to ineffective leadership that are not Koch-culture fits (makes you wonder how they ended up in their positions). Incentives are incredibly misaligned with the amount of work put in by individuals at this company. Bonuses and salaries are not competitive with the market (they will disagree, but I know this first-hand), and they are losing out on good talent because salaries and bonuses are embarrassingly below competitors.
