How is this different from a coding test?

Codility assessments are practical coding tasks drawn from 1,300+ validated tasks, each reviewed by subject-matter experts and documented in a published Technical Manual. Candidates work in a browser environment with VS Code, a terminal and multi-file projects on supported tasks. The result is a scored solution and a record of how it was produced.

How long should a screening assessment take?

The hiring team sets the task set and time limit for each role. Codility helps scope it to the skills the role requires, then reviews completion and drop-off data with the customer.

How do you control AI use and protect assessment integrity?

Allow the AI Assistant or turn it off for each task, and every prompt and response is saved for review. Identity, behavioral and similarity checks surface sessions that need attention. A reviewer inspects the signals before any decision. No integrity signal rejects a candidate on its own.

Does it work with our applicant tracking system?

Yes. Recruiters send invitations and receive scores and reports inside the applicant tracking system they already use. The integrations page lists supported systems.

Can we defend the pass mark if a candidate or a regulator asks?

Codility documents task content validation in its Technical Manual and monitors adverse impact at measured cut scores for the groups it measures. Automatic task scoring follows fixed rules. Professional Services can run a local validation study on the customer's own roles and data.

Can we screen business roles the same way?

Yes. AI for Business runs inside Screen. Candidates complete a business task with an AI assistant, and fixed rules score the deliverable. Coverage includes sales, marketing, finance, operations and customer roles. Included in your plan.

Technical screening to one standard, at any volume

Screen every engineering applicant the same way, in every region. Recruiters see scores and integrity signals in their ATS and build the shortlist.

Synced to your applicant tracking system

Hundreds of applications per role. No fair way to shortlist.

01

Recruiters read every CV by hand, and strong engineers with weak CVs never get seen in favor of candidates shown as perfect by AI

02

Each team writes its own take-home, so two candidates for one role face different bars

03

Engineers spend hours reviewing submissions or running interviews that should never have reached them

04

At volume, AI use and assessment integrity are harder to check and harder to explain later

One screening step from application to shortlist

Set one standard per role

Set one assessment per role family or function with your engineers and our assessment scientists. Choose from 1,300+ validated tasks across 80+ languages and frameworks, or add your own. Apply the same standard across regions, business units, or entities.

Invite at any volume from your ATS

Send invitations from your applicant tracking system, for one candidate or several thousand. Candidates complete the tasks in their own time, in a browser or using the Codility Desktop App. Results return to the candidate record automatically.

Allow AI or turn it off, then review the integrity signals

Allow the AI Assistant or turn it off for each task, and every prompt and response is saved for review. Identity, behavioral and similarity checks contribute to an integrity risk rating. Recruiters review the flagged sessions and make the call.

Shortlist by score, and refine the pass mark

Selected task types score automatically against fixed rules. Sort candidates by score and integrity rating. Our assessment scientists help set and refine the pass mark as results arrive.

Hand engineers a shortlist worth their time

Engineers review the code behind the shortlist. Open a candidate’s solution and replay how it developed. When you create an interview from a Screen report, the candidate’s VS Code solution comes with it.

A screening standard your engineers and your legal team both accept

A consistent shortlist needs practical work, shared scoring criteria and results your team can explain.

Codility combines practical tasks, integrity signals and a documented method, and fixed rules score the work so your legal team can review how scores are produced.
