What Valve actually looks for
Valve, based in Bellevue, Washington, is privately held and runs both Steam, the dominant PC game distribution platform, and its own game franchises like Half-Life, Portal, Counter-Strike, and Dota 2, plus the Steam Deck handheld. Valve is famous within the industry for its flat organizational structure, described in the leaked internal Valve Handbook, where there are no formal managers and employees are expected to choose their own projects by physically moving their desks, sometimes described as desks on wheels. This means Valve interviews screen heavily for self-direction and judgment rather than for fitting into a predefined role, since new hires are largely expected to figure out where they add value rather than being told. Valve has a very small headcount relative to its revenue and historically posts far fewer public job openings than its size would suggest, making the bar for entry unusually high, with a strong preference for candidates who've shipped real, polished work before.
Common questions and how to answer them
How do you decide what to work on when nobody assigns you a task? This is central to Valve's flat structure, so answer with a real example of identifying and pursuing a valuable problem without being told to, not just following a backlog. Tell me about a time you changed direction on a project based on your own judgment. Valve wants evidence of independent decision-making, since there's no traditional management layer to defer to. How would you think about Steam's role in the broader PC gaming ecosystem? Relevant for platform roles; show you understand Steam's position as both storefront and social platform, and how decisions there affect thousands of third-party developers. For each of these, avoid answers that imply you'd want more structure or oversight than Valve actually provides, since that signals a mismatch with how the company genuinely operates.
How to prepare
Read about Valve's flat structure and the Valve Handbook before interviewing, since candidates who don't understand it tend to give answers that sound like they're looking for a manager to tell them what to do. Have a portfolio of genuinely finished, polished work, since Valve's small team size means every hire is expected to operate at a high level with minimal oversight. Be ready to talk about Steam as a platform business, not just about Valve's own games, since much of Valve's actual work is platform and infrastructure engineering. Expect an unusually informal-sounding but genuinely rigorous conversation focused on what you've actually built and why, since Valve cares less about matching a job description than about proven capability.
