Does Codility Record Your Screen During Assessments?
2025-10-15
If you are taking a Codility assessment, this question usually comes up fast.
Does Codility actually record your screen while you are coding?
The short answer is no. Codility does not record your screen as a video during standard assessments. There is no hidden screen capture running in the background.
As with most hiring platforms, the reality is more about behavior tracking than recording footage.
What Codility does not do
Codility does not:
- Record a video of your screen
- Capture everything you see on your monitor
- Monitor other applications at the operating system level
- Track what is happening on other screens
Your screen is not being saved or replayed later for someone to watch.
What Codility does track
Codility focuses on signals inside the browser and the coding environment itself. These can include:
- Time spent on each task
- How often the test tab loses focus
- Code changes and execution attempts
- Copy and paste behavior
- Final solution quality and performance
This data helps recruiters understand how you approached the problem, not what was on your screen.
Why screen recording rumors exist
Codility assessments often feel strict. Timers, warnings, and instructions about fairness make people assume there must be screen recording involved.
In practice, Codility relies on metrics and patterns, not surveillance footage.
The confusion usually comes from mixing up screen recording with tab focus tracking.
Does using another screen matter?
Using an external monitor or another device does not automatically raise flags.
What matters is whether your actions cause the Codility test tab to lose focus repeatedly or show suspicious behavior patterns.
If the test stays active and your interactions look normal, there is nothing unusual being logged.
How to reduce risk during a Codility test
The safest approach is to stay inside the test environment and avoid unnecessary window switching or copy paste actions.
Many candidates prefer tools that help them think through problems without touching the browser at all.
StealthCoder was built for this exact situation. It runs outside the browser, avoids tab switching, and helps you stay focused without creating activity that Codility might log.
Knowing what is tracked lets you focus on solving the problem instead of worrying about invisible monitoring.
