Pros
When Koch says they hire on virtues before talent, they truly mean it — I'm a living example. I've held two roles in my tenure so far at Koch — one where I've had prior experience and my current one, which is/was a stretch role. Based on my values, I was given an opportunity I did not expect as part of my career trajectory. It gives me great respect for this company and its leadership and shows me we actually live out our Guiding Principles. They are so much more than simply a poster on the wall.
Cons
With a company our size, there will inevitably be folks who slip through the cracks when it comes to values and principles. I've worked with people who do not live out the Guiding Principles. I've also seen those people have a short tenure at Koch. I also think, at times, there is to much bureaucracy in getting things accomplished or trying new things.
