This is a common question from people interviewing at Valve. I was suspect how accurate it was before I joined given how long it's been since it was updated. However, it still 100% represents the culture within Valve. Desks are still on wheels, structure is still completely flat, etc...

It's been on my list of "eventual todos" to make a trivial update to help reinforce that it's still relevant.

Personally I'm interested in this proposed flatness. I understand that it's the aim, but at the end of the day someone approves vacations, manages budgets for projects and is the person that has to have hard conversations with an employee right? Someone will have higher mandate for hard decisions?

How is individual performance evaluated?
