Using AI in a Live Coding Interview

Live coding interviews on Zoom, Google Meet, or Microsoft Teams typically mix three things: a spoken problem statement, a shared editor (CoderPad, HackerRank, CodeSignal, or a Google Doc), and follow-up questions about complexity and edge cases. An AI assistant is most useful for the spoken and conceptual parts:

• Transcribing the problem so you don't mishear constraints.
• Suggesting candidate approaches (brute force, then optimized).
• Reminding you of time and space complexity.
• Listing edge cases (empty input, duplicates, overflow, negative numbers).
• Drafting pseudocode you can then translate and adapt.

What it cannot reliably do is replace your own reasoning when the interviewer asks why you chose an approach. You still have to think out loud.

Coding rounds are where AI tools are easiest to misuse and easiest to spot. Be honest about the limits:

• Screen sharing: if you share your full screen, anything visible — including an AI overlay — is visible to the interviewer.
• Shared editors: pasting large blocks of perfect code into CoderPad or HackerRank, especially without typos or pauses, looks suspicious.
• Proctored environments and company-managed laptops: these can restrict installs and may log activity. SubcueAI is not designed for those.
• Webcam and eye tracking: obvious off-screen reading is noticeable on camera.

SubcueAI is a native desktop app for macOS and Windows. It captures both your microphone and system audio locally, transcribes the interviewer in real time, and shows suggestions in a floating overlay on your own screen. A few properties matter for coding rounds:

• It is not a meeting bot — it does not join the call as a participant.
• It is not a browser extension, so it does not appear in the meeting tab.
• The overlay is local to your machine; if you share only the interview tab or the coding editor window (not your full screen), the overlay stays off the shared view.

That last point is on you to configure. Practice your share setup before the real interview. See the tutorial for setup steps and how it works for the audio pipeline.

A workable approach for a live coding round:

• Before the call, decide which window you will share — ideally only the coding editor, not the whole desktop.
• Let the AI transcribe the problem and surface candidate approaches.
• Pick an approach yourself and explain it out loud before writing code.
• Type the code yourself at human speed; use AI suggestions as a reference, not a paste source.
• Use it most heavily for complexity analysis and edge cases, which are where strong candidates often lose points.

Used this way, AI acts like a study partner sitting next to you, not a ghostwriter.
