A CoderPad interview AI assistant and copilot.
A CoderPad interview is a shared document with a witness: the interviewer watches your cursor, your pauses, your backspaces. Interview Clozo never touches that document. It is a native macOS AI interview copilot that hears the interviewer through your audio devices, reads the problem with vision on paid plans, and shows guidance in a window macOS excludes from capture — outside the shared content entirely.

Yes, and it never touches the pad itself. Interview Clozo is a native macOS app: it puts nothing in the CoderPad page, installs no browser extension, and types nothing into the shared editor — it hears the interviewer through your audio devices and reads the problem with vision on paid plans, while you write the code yourself.
Five questions. Five kinds of answer. One window.
Watch one round, five questions back to back — the answer stack reshapes itself for each one.
What this demo shows: one live interview round in Interview Clozo, five questions back to back.
- Behavioral, already answered when the round opens: “Tell me about a time something went wrong on a project you owned.” The Short Answer tells the candidate’s own story from their resume — detection cut from 38 hours to under 5 minutes.
- System design: “How would you architect a link shortener?” System Design Clarifying Questions appear above the Short Answer, then Shift+Down opens the Diagram of the architecture.
- A technical follow-up: “You mentioned the edge cache. What if one link goes viral?” The answer builds on what the candidate had just said.
- Coding: “Write a function that merges overlapping intervals.” The Short Answer gives the approach to say, then the Code pane shows Python with a comment on every line.
- Math: “Rough numbers — how much storage for a billion links?” The Math pane works it out: about 1.5 terabytes.
- Shift+Left walks back to Q1 with every answer still there.
How does Clozo work alongside CoderPad?
Nothing in the DOM
Clozo installs no browser extension, injects no content script, and adds nothing to the CoderPad tab — there is nothing in the page for pad-side JavaScript to enumerate. CoderPad’s own position, per its documentation, is that it “does not directly detect external AI tools running on the candidate’s desktop” — a native app lives exactly there.
It hears the interviewer
Clozo captures your microphone and the Mac’s audio output device, so the interviewer’s questions stream in as transcription the moment they’re spoken — whether the CoderPad session runs in Chrome, Safari, or alongside a Zoom or Meet call. No tab is shared with anything, so no tab-audio capture can silently fail mid-interview.
Answers outside the shared content
Guidance renders in Clozo’s cockpit — a separate window that macOS excludes from screen capture at the window level, verified live in the app. Share the pad, share a window, or share your whole screen: the cockpit is not part of the captured content. Every axis is cross-examined on the Undetectability Matrix.
The talk-through first. The code underneath.
Watch one spoken coding question and its follow-up: the talk-through lands first, the commented code sits underneath.
What this demo shows:
- The interviewer asks: “Given an array of meeting times, write a function that returns the minimum number of rooms.” The Short Answer gives the approach to say out loud: sort by start time and keep a min-heap of end times. The Code pane shows a Python listing with a comment on every line and its time and space complexity.
- The interviewer follows up: “Can you write it without a heap?” The follow-up gets its own card, with a new Short Answer (two sorted lists and two pointers) and its own commented listing.
- One key brings the first answer back.

What can a CoderPad interviewer actually see?
Everything you do inside the pad: every keystroke as it lands, every pause, every paste. That visibility is the product. What gets copilot users caught on CoderPad is not the overlay — it’s operating the copilot through the pad itself. Candidates reported CoderPad and HackerRank flagging a rival overlay’s Cmd+Enter hotkey keystroke, and a candidate-built JavaScript keylogger proof of concept showed pads can observe key events (r/Cluely and r/cscareerquestions, May 2025).
Clozo’s interaction model sidesteps this: you never operate it by typing into the shared editor. You read the guidance and write your own solution in your own words — which is also the right posture for paste detection and after-the-fact similarity scoring. The remaining tells are human ones: long silences while you read, eyes parked off-camera. Keep the cockpit near your camera line and talk while you think.
“CoderPad and HackerRank will detect if you use the cmd+enter hotkey while in the code editor.”
r/Cluely user report, May 2025 — the hotkey inside the shared editor was the tell, not the overlay. Clozo is never driven by keystrokes in the pad.
“…does not directly detect external AI tools running on the candidate’s desktop.”
CoderPad’s own documentation position on desktop tools. Clozo puts nothing in the pad, the DOM or the browser — and the cockpit stays off the shared screen.
Where is the cockpit during a CoderPad session?
CoderPad sessions often include a “share your screen” moment before or during the pad work. Your cockpit is excluded from screen sharing by macOS itself, at the window level — window share, entire-screen share and recordings alike. They share their screen; your cockpit is not on it, and you can confirm that live state in the app before the interview starts.
Nothing else is in reach either: no extension, no content script, nothing injected into the pad or the DOM for a browser-side check to enumerate, and nothing joining the call. The Short Answer pane is written to be spoken and is on your screen about a second after the app has the question, so you talk through the approach at conversation pace while you type your own solution. One-time setup — see the install guide.
How do you prepare for a CoderPad interview?
- 1. Install Interview Clozo on your Mac. Download from the install page and grant microphone permission when macOS asks.
- 2. Choose your microphone. The interviewer’s side comes straight from your Mac’s system audio (all apps, or only the apps you pick): no virtual audio device, nothing to route. Because capture is device-level, any browser works — Chrome, Safari, Arc, whatever the invite link opens.
- 3. Rehearse in CoderPad’s sandbox. Open a practice pad, have a friend play interviewer on a call, and confirm answers stream while you type. Confirm in the app that the cockpit is off the shared screen.
- 4. Keep your hands in the pad, your eyes near the camera. Read guidance in your own voice and code your own solution — never paste, never operate anything via the shared editor.

CoderPad interview copilot — FAQ.
No. Interview Clozo is a native macOS app: no browser extension, no content script, nothing injected into the CoderPad tab and nothing in the DOM for pad-side JavaScript to enumerate. It listens to your Mac's audio devices and renders guidance in a separate window outside the shared content. CoderPad's own documentation position is that it 'does not directly detect external AI tools running on the candidate's desktop.'
The documented flagging cases are about operating a copilot through the pad: candidates reported CoderPad and HackerRank picking up a rival overlay's Cmd+Enter hotkey keystroke (r/Cluely, May 2025), and a candidate-built JavaScript keylogger showed pads can observe key events. Interview Clozo is never driven by keystrokes in the shared editor — you read the guidance aloud and type your own solution, so there is no copilot hotkey for the pad to see.
Yes. The Short Answer lands first with the approach and its complexity, in words to say; Technical Details and a Code pane with a comment on every line build right behind it. When the problem is written in the pad, F3 reads it off your screen, so guidance is grounded in the actual prompt. The Short Answer pane gives you the talk-through — trade-offs and reasoning — that CoderPad interviewers grade as heavily as the code.
