AI for Codility Tests

What should candidates know about Codility?

Codility can be used for Codility Screen assessments and live interviews with employer-configured integrity, timing, language, and collaboration settings. That does not create one universal compatibility result. GhOst does not currently publish a continuously verified pass-or-fail matrix for Codility; behavior can change with Screen versus interview product, employer configuration, integrity features, hidden tests, performance constraints, device checks, and permitted resources. Treat this page as preparation and testing guidance, not a promise that a privacy control will behave the same in every configuration.

Which variables should you record?

• Operating environment: Windows or macOS version, device type, display arrangement, permissions, and accessibility tools.
• Platform environment: Screen versus interview product, employer configuration, integrity features, hidden tests, performance constraints, device checks, and permitted resources.
• Interview format: meeting, practice task, live editor, take-home work, or monitored assessment.
• Policy: the employer's or administrator's written rules for notes, documentation, calculators, accessibility tools, and AI assistance.
• Evidence: date, tester, expected result, actual result, recording or screenshot location, and known limitations.

How should you run a safe mock test?

1. Use a meeting, practice task, or environment you own or have permission to test. Never probe a live assessment or another person's system.
2. Practice correctness and complexity against hidden-style edge cases, then rehearse explaining the same solution without relying on generated wording.
3. Test each relevant share or capture mode separately. A window, browser tab, full display, cloud recording, and external camera are different surfaces.
4. Confirm audio, OCR, shortcuts, permissions, and fallback behavior. Stop the mock if a privacy or accessibility control behaves unexpectedly.
5. Record the exact versions and retest after an OS, platform, browser, or GhOst update. Treat an old result as expired.

What policy and accessibility checks come first?

Read the invitation and platform instructions before the session. Ask the recruiter or administrator when permitted resources are unclear. Request accommodations early enough for approval and a technical rehearsal. Preparation, mocks, open-book or take-home work, and explicitly authorized assistance are the safe defaults; do not use GhOst to evade monitoring, identity checks, or rules that prohibit outside help.

How does GhOst fit this workflow?

GhOst provides managed AI on Windows and macOS for coding, behavioral, and system-design preparation. Its desktop privacy controls are designed for supported capture workflows, but no software can guarantee zero detection risk. Keep a no-assistance fallback and be able to complete and explain your work independently.
