We value “T-shaped” people.
That is, people who are both generalists (highly skilled at a broad set of valuable things—the top of the T) and also experts (among the best in their field within a narrow discipline—the vertical leg of the T).
This recipe is important for success at Valve. We often have to pass on people who are very strong generalists with-out expertise, or vice versa. An expert who is too narrow has difficulty collaborating. A generalist who doesn’t go deep enough in a single area ends up on the margins, not really contributing as an individual.
