Interview Platform Proctoring: What Each One Records

What HackerRank, CodeSignal, Codility, CoderPad, Karat, HireVue, Zoom, Meet and Teams actually record in a technical interview — sourced to each vendor's docs.

How these pages are written

Every claim on every page below was read off that vendor's own public documentation, and the page carries the link it came from. Where a vendor's documentation is silent, the page says so instead of guessing — that is the part most write-ups on this subject get wrong, and it is the part that matters when you are about to sit the thing.

We do not claim any product is undetectable on any named platform, ours included. Nobody outside these vendors can test that.

Sources last checked against vendor documentation in August 2026.

Take-home & timed assessments

You sit these alone, against a timer. This is where proctoring features live: webcams, screenshots, browser lockdown and, increasingly, desktop applications.

Live coding interviews

A human is on the other end. The monitoring is mostly the interviewer plus a keystroke record of the editor, not a camera pointed at your room.

Video meeting platforms

Meeting software, not proctoring software. What is captured is what you chose to share, plus your camera and microphone.

Recorded, flagged, or blocked

Each platform page tags every control with one of three words. Candidates routinely collapse them into "they can see everything", and they are not the same thing at all.

Recorded

An artefact is stored and a reviewer can look at it later.

Flagged only

An event is noted on the report. Nothing is stored to look at.

Blocked

The action is prevented rather than observed.
