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.

Why Codex Interview is the Future of Coding Interviews

If you've spent any time searching for a coding interview assistant, you've probably found Interview Coder — the AI tool created by Roy Lee, a Columbia University student, that went viral on GitHub and Reddit. The idea is simple: an invisible AI app that solves coding problems during live technical interviews. But here's what the marketing doesn't tell you: AI interview assistants like Interview Coder have a fundamental flaw. They hallucinate. They lag. They get detected. And when they fail, you're the one who gets blacklisted — not the tool. In this review, we'll break down exactly why Interview Coder falls short, what makes it detectable on platforms like CoderPad, HackerRank, and CodeSignal, and why Codex Interview has become the go-to Interview Coder alternative for developers targeting roles at Google, Meta, Amazon, and other top tech companies.
