AI makes weak candidates look strong and cheating harder to spot. From screen to interview, Codility shows who has the judgment to use it well.
For almost two decades, companies have used Codility to hire engineers. Now we show how engineers and business teams use AI at work. See what changed in two minutes.
AI can write the résumé. The code. The pitch. So everyone looks qualified on paper. But who can actually do the job?
Codility shows you. You may know Codility for coding tests. We rebuilt them, and the whole platform, with AI at the center. Now it’s for engineers and every other role. People do real-world tasks, with the AI tools they use day to day. You see exactly how.
Hiring engineers? They build in a real coding environment, with Claude Code and our AI Assistant. The report shows every prompt, every fix, and any red flags. Then spend your interview time on the strongest candidates. Tell the AI to slip in a bug, and see who catches it.
Hiring for any non-technical role? Sales, marketing, finance, operations, customer service. They get a task from the job, an AI assistant, and the data they need. Score the same work a thousand times, and you get the same score a thousand times. An AI grader can’t promise that.
Then run the same tasks with the people you already have. See which engineers are ready for what, which teams use AI well, and who to upskill next. Everyone you hire. Everyone you have. One standard.
Your team always makes the final decision. If a candidate, a regulator or a client asks why, you can show them. Almost two decades of assessment science stand behind every score. And our IO psychologists design every assessment.
Codility. Proof of who can do the job.
See how people use AI on the tasks you set and the report your team uses to decide who to hire or upskill.
Interview engineers as they build with AI, and see who checks its work
Every assessment produces integrity signals. Codility combines them into one overall risk rating for your team to review. When AI is allowed, every prompt and response is saved.
Available controls depend on the assessment type and configuration.
Hire developers and assess the engineers you already have.
Hire and develop people who can use AI in every function.
