What Lixir is

Lixir is a voice-based AI interviewer for software engineers practicing coding interviews in a live editor. It follows code as it is written, asks follow-up questions, and can offer a nudge when a user gets stuck. Practice modes include silent proctor, guided, and pair partner. Users can run code in JavaScript and TypeScript, or talk through problems in Python, Java, or Go. A job description, resume-based practice, and role-specific coaching can shape preparation. After each session, reports assess coding, problem solving, communication, and collaboration, with session evidence and suggested next steps. Lixir works in a modern browser such as Chrome, Firefox, Safari, or Edge and requires a microphone and stable internet connection; no installation is needed. The Free plan costs nothing and includes one practice interview and three coding challenges. Pro is $20 a month, with unlimited interviews and challenges, scored reports, and resume-based personalization. The pricing note also lists a starting price of $29. The service is intended for users aged 18 or older.
