How long should a graduate coding assessment take?

The task set and time limit should match the skills being assessed. Codility works with the program team to manage candidate effort, then uses completion and drop-off data to inform adjustments.

Can we validate the assessment for our roles?

Standard tasks carry documented content validation with subject-matter-expert review. Professional Services can run a local validation study for the customer's roles. Standard library validation and a local study are separate.

Can we check whether pass rates differ by background?

Codility monitors adverse impact at measured cut scores for the populations it measures. Analysis of a customer's cohort uses demographic data supplied by the customer. Codility does not infer demographics.

Where does Codility fit alongside Cappfinity?

Codility provides the technical assessment stage alongside the program's strengths, behavioral and cognitive assessments. The integration supports invitations and results in the existing workflow.

Can interviewers review how a candidate used AI?

Yes. Enabled AI interactions remain in the candidate record, and the report shows which AI skills the candidate used, with quotes from their own prompts as proof. Claude Code and Codex run across Screen, Interview and Skills Intelligence. Integrity signals are available for human review whether the assessment allows AI or not.

Thousands of applications in one season, and résumés show little of who can code

01

Every market shortlists differently, and CVs offer little evidence of coding ability.

02

Long assessments risk losing candidates before they show their skills.

03

Questions about AI use and pass rates need answers before the next round.

Build the assessment around the program

Choose role-relevant tasks and time limits with your engineers and our assessment scientists. Apply the same criteria across each program’s markets.

Allow AI or turn it off, and focus the review

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. Reviewers inspect the signals and make the call.

Keep candidates moving through your workflow

Send invitations and receive results through your applicant tracking system. Selected tasks from the Codility Task Library score automatically. Review completion and drop-off, and configure accommodations such as extended time where needed.

Use a shared rubric for the live round

For programs with a technical assessment center, Codility Interview gives interviewers a shared coding environment and rubric. The transcript and playback preserve the evidence behind their feedback.

Learn from this season’s results

Codility’s Professional Services team supports assessment design, pass marks and campaign analysis. Review completion, score distributions and pass rates. Cohort fairness analysis uses demographic data your organization supplies.

A technical assessment your whole program can stand behind

Multi-market programs need role-relevant tasks, a documented method and support interpreting results.

Codility pairs practical tasks with assessment scientists who support program design and campaign analysis. Fixed rules score the work, and reviewers see how scores and pass rates are produced.
