What it is

Lixir is a web-based, voice-driven 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 nudge users who are stuck. Practice modes include silent proctor, guided, and pair partner. Code can run in JavaScript and TypeScript, while problems can be discussed in Python, Java, or Go. Users can provide a job description, practice from a resume, and use role-specific coaching. Post-session reports assess coding, problem solving, communication, and collaboration, with session evidence and next steps; feedback also covers overall assessment, competency breakdowns, strengths, and improvement areas. The Free plan costs nothing and includes one practice interview, three coding challenges, real-time coaching, reports after each session, and permanent report and profile retention. Pro costs $20 a month with unlimited interviews and challenges, scored reports, and resume-based personalization.
