High volume hiring platform for engineering_
Codility Screen provides technical assessment for high-volume engineering hiring. Your talent team can review task results in a connected applicant tracking system (ATS) before choosing a shortlist.
Global enterprises that trust Codility include
Trusted by GitHub, SpaceX, Tesla, EY, LSEG, SAP, Barclays.




G2 rankings come from verified customer reviews, not paid placements, and are updated quarterly.
Today’s failing approach: applicant volume exceeds your team’s review capacity
01
Manual resume review
Recruiters read applications one at a time. A well-written resume gives limited evidence that a candidate can build software.
02
Engineering review
Live technical screens require engineering time for each candidate. Interview demand has to compete with project commitments.
03
Fragmented results
Separate task sets and spreadsheets make candidates harder to compare across teams and regions.
Add technical assessment to your hiring process
Codility Screen provides the engineering assessment step alongside your sourcing, scheduling and candidate communication tools. You set the criteria, and your team decides who advances.
Track assessment completion from your existing ATS
Manually rebuilding an applicant list adds administration to a large campaign. Codility connects with platforms, including Greenhouse, Lever, Ashby, Workday, SAP and SmartRecruiters.
Candidates receive individual invitation links through your assessment workflow. The campaign view shows invited, started and completed assessments, and results return to the candidate record.
The difference: Your team can check assessment progress without maintaining a separate completion spreadsheet.
Review ranked results before opening individual submissions
Manual marking adds work for each candidate. Selected Codility tasks score automatically against defined test cases. Your engineers can review the ranked results and inspect submitted code when a result needs closer attention.
The difference: Your team can prioritize candidate review using assessed output.
Review integrity signals with the supporting evidence
Watching full assessment sessions can create a substantial review workload. Codility collects integrity signals, including behavioral and similarity signals, and presents a reviewable risk level.
Reviewers can inspect the contributing signals and the task timeline. A risk level supports review; a person makes the hiring decision.
The difference: Your reviewers can investigate identified signals alongside the candidate’s output.
Customer results from assessment at volume
Chris Weber at Unity reported:
“With Codility, our teams ran 750 candidate tests over 90 days, saving 2,200 hours of interview time. That kind of productivity is like gaining time to launch an entirely new product or enter a new vertical.”
