Company profile
Character.AI
Character.AI runs a consumer AI chat platform where users create and interact with model-backed characters at large scale. Engineering interviews are likely to emphasise realtime product systems, safety controls, recommendation loops, and the practical limits of serving conversational models to a broad audience.
Interview process
Character.AI operates as a research organization, so interviews at this kind of employer usually go deep rather than broad: past projects, publications where relevant, and how you reason about open problems. Panels tend to include working researchers rather than dedicated interviewers. The role pages below show what to prepare for ml engineer, ai engineer, ai infrastructure engineer positions.
