Does TestGorilla Detect Cheating?

2026-09-07

TestGorilla tests are timed, full-screen and camera-on. It is easy to assume every move you make is being judged.

Here is what TestGorilla actually documents.

Yes, TestGorilla monitors for cheating, but it does not label anyone a cheater. Its help center says "we cannot say for certain that a candidate has attempted to cheat." It collects signals, sorts candidates into risk tiers, and leaves the decision to the employer.

What TestGorilla monitors

TestGorilla lists these behaviors in its anti-cheating article:

• Webcam snapshots: "The system captures images of the candidate every 15 seconds to verify their identity."
• Full-screen: "We monitor whether a candidate stays within the full-screen test window or exits the mode."
• Tabs: "We detect if a candidate switches browser tabs during the assessment."
• Camera status: "The system tracks if the camera is disabled or turned off."
• Developer tools: "The system logs if a candidate opens browser developer tools."
• Location: "We record the approximate location and IP address to identify potential unauthorized attempts from the same user."
• Pasting, by "tracking when and where content is pasted."

How the flags get sorted

Every candidate lands in one of "three risk levels: No Issues, Some Issues, and Major Issues."

The top tier is for "Significant signals detected, such as frequent full-screen exits or the webcam being disabled." TestGorilla also says plainly that "An event being flagged is not automatically a bad thing."

Other measures built into the test

A few protections sit in the test itself:

• Questions rotate, so "different questions are selected and presented every time a test is used in an assessment."
• The clock does not stop: "Once a test starts, the timer will continue running."
• You sign an honesty agreement confirming you will complete it "without using AI tools, retaking the assessment multiple times, or engaging in any other behaviors prohibited by our Candidate Honesty Policy."

What the hiring team does with it

TestGorilla tells employers: "We do not recommend rejecting candidates based on this information alone." It suggests contacting the candidate first.

The signals are all browser events: tab switches, full-screen exits, pastes. That pattern is common across platforms, as covered in does Codility track tab switching.

Working without leaving the test window

StealthCoder is a desktop app that runs separately from the browser. It reads the problem on screen and helps you work through it, so you are not switching tabs or pasting from somewhere else.
