How Codex Interview Works

How Codex Interview's real-time collaboration works: the desktop app, the shared coding pad, and why room-scoped screen sharing and session playback exist.

A Native Desktop App, Alongside Your Browser

Codex Interview isn't a browser extension or an in-page script. It's a native desktop application that runs alongside your interview platform's browser tab, giving you a dedicated coding pad you can position anywhere on your screen, with more room to work than a small editor embedded in someone else's page.

Real-Time Collaboration

Codex Interview streams your code edits and your teammate's feedback over a secure WebSocket connection, so you both see changes the moment they happen. Position the pad wherever works best for your setup, and keep coding without breaking your flow.

Why Room-Scoped Screen Share & Watch Exist

Sometimes a teammate needs to see more than just the pad, like your terminal, a browser dev tools panel, or the interview platform's own editor, to help you debug an environment issue or give closer live guidance. Screen share and watch are scoped to your room and fully opt-in: both participants can see when it's active, and either side can turn it off at any time.

Session Playback

After a session ends, playback lets you replay the whole interaction, code changes and chat, so you and your partner can review what worked and study for next time.
