Today’s failing approach: applicant volume exceeds your team’s review capacity
01
Failing approach 1: Manual resume review
Recruiters read applications one at a time. A well-written resume gives limited evidence that a candidate can build software.
02
Failing approach 2: Engineering review
Live technical screens require engineering time for each candidate. Interview demand has to compete with project commitments.
03
Failing approach 3: Fragmented results
Separate task sets and spreadsheets make candidates harder to compare across teams and regions.
Add impartial 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 decide 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 the results are stored in the candidate record.
The difference: Your team can check assessment progress without maintaining a separate completion spreadsheet.
Review ranked results before opening individual submissions
Codility automatically provides scores for all test cases. Your engineers can review the ranked results and inspect submitted code when a result needs closer attention. No manual marking is required, which reduces the work per candidate.
The difference: Your team can prioritize candidate review based on assessment output.
Review integrity signals with the supporting evidence
Watching full assessment sessions to identify cheating can create a substantial review workload. Instead, 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 review identified signals alongside the candidate’s output.
What our customers say about Codility assessment at volume

“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.”
