If your assessment or interview requires the Codility App, you'll need to download and install it before you can begin. Taking Your Assessment or Interview in the Codility App
If your assessment or interview does not require the Codility App, you will need to use a supported browser (Chrome ≥ 131, ChromiumEdge ≥ 130, Firefox ≥ 132, Opera ≥ 114, Safari ≥ 17) to complete the assessment. You will not need to install any applications or browser plug-ins. The Codility interface contains a coding environment that provides everything you need to solve the tasks (you can edit, compile, and run your solutions as many times as you’d like before submitting your code). If you prefer to use other programming tools, see: Can I use my own IDE?
