Honestly, the best thing about Codility is how much time it saves me. I use it regularly for interviews, and it's basically plug-and-play. The fact that I don’t have to spend hours inventing and testing coding questions is a lifesaver—their built-in question bank is huge and actually relevant, which saves our engineering team a ton of hours every single week. The coding IDE itself is great. It’s super clean, doesn't lag (great performance), and it's technology-agnostic, meaning candidates can code in whatever language they're comfortable with while I get a smooth, platform-specific view. The AI features are another huge win. Instead of me sitting there trying to play detective, the AI agent monitors the solutions, checks for candidate integrity, and flags any weird behavior with alerts. It lets me focus on how they actually solve the problem rather than worrying about cheating. Getting it set up and onboarding the rest of the team was frictionless, and honestly, the ROI speaks for itself when you calculate how many engineering hours we get back. The integration experience has been practically seamless. We connected Codility directly into our Applicant Tracking System (ATS), and it has completely cleaned up our daily workflow. Instead of jumping back and forth between different browser tabs to copy-paste data, everything happens right inside our main recruitment tool. We can trigger a Codility test invite automatically as soon as a candidate moves to the screening stage, and once they finish, their scores and the full report link sync straight back to their profile.

Great platform for taking the interviews. Saves a lot of time.

The tech stack integration is a good addition for framework related interviews. Real world engineering tasks are a good addition in the era of AI. The IDE has become better with respect to UX
