Can CoderPad detect cheating?
By Aaron Cao · Updated

The live pad has no webcam proctor. The signal is a human watching your keystrokes in real time plus session playback, which makes a pasted block obvious afterwards. CoderPad's async assessment product adds tab-switch and paste logging.
What can the interviewer actually see in a live pad?
The worry is usually a hidden detector running in the background. On a live CoderPad the honest answer is smaller and more uncomfortable: there is no detector, because there does not need to be one. This section covers what the interviewer sees on their side of the shared pad while you work.
The pad is collaborative, so your editor is their editor. They see characters arrive as you type them, cursor jumps, deletions, and any block that appears all at once. They see which language tab you are on and when you run the code. Some teams run the call inside CoderPad and some run it on a separate meeting app, which changes nothing about the pad itself.
Nothing there is automated scoring. It is a person forming an impression in real time, which is both less systematic and harder to argue with than a flag in a report.
Does session playback catch pasted code?
Playback is the part candidates underestimate. The session can be replayed afterwards, showing the order in which the solution was built. Code typed line by line, with false starts and corrections, replays differently from a working solution that appears in one frame.
A frontend engineer interviewing for a mid-level role at a payments company solved the problem correctly, then spent the debrief explaining a helper function they could not walk through line by line. The playback was not what sank it; the explanation was. The two together are what a hiring team weighs.
More platform breakdowns of what is and is not observable sit on the detectability topic hub.
What does an async CoderPad assessment log?
The take-home style product is closer to other assessment platforms. Expect timestamps for window focus changes, records of large paste events, and total time spent per question. Those land in a report a recruiter or engineer reads next to your code.
None of that is a verdict on its own. A single tab switch to read documentation is normal and reviewers know it. A pattern of long absences followed by finished blocks of code is what changes how a report reads.
How SubcueAI handles interview audio, and what it keeps, is written out on the security page.
Where SubcueAI fits in a CoderPad round
SubcueAI is built for the spoken part of an interview. The native macOS and Windows app captures system audio plus your microphone and shows suggestions in a floating local overlay. The browser extension's Side Panel does live assist for a meeting tab on Chromium browsers, capturing that tab's audio only, so it never transcribes you. No meeting bot joins the call, and nothing is injected into the meeting page.
A CoderPad round is mostly not that. If you share your screen, a local overlay is inside what you share, and that is a hard limit rather than a setting to adjust. If the pad is recorded, the same applies. Where an assistant earns its place around a coding round is the conversation on either side of it: the walkthrough of your approach, the follow-up questions, and the behavioral rounds that come with the loop.
For the coding round itself, timed rehearsal is the honest preparation, and it runs on the mock interview page.
