Lixir
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 you write, asks follow-up questions, and can prompt you when you 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. You can provide a job description, practice from a resume, and use role-specific coaching. After each session, reports assess coding, problem solving, communication, and collaboration, with session evidence and next steps. The Free plan costs nothing and includes one practice interview, three coding challenges, real-time coaching, performance reports, and permanent report and profile retention. Pro costs $20 a month and adds unlimited interviews and challenges, scored reports, and resume personalization. Lixir requires a microphone and stable internet connection.
