Today’s failing approach: comparing a talent assessment company by features alone
Library size
A high question count does not tell you whether the questions are calibrated for difficulty or whether the assessment has adverse impact data at your intended cut scores.
Polished demos
A vendor can show the candidate experience and the final report without explaining how it validated the scores.
One vendor per role family
Your talent team may use one vendor for business roles and another for engineering. Each vendor requires a separate security and legal review, and each produces results using a different method.
Software without assessment expertise
A self-serve tool can leave your talent team to design every assessment without help from assessment specialists.
Feature-led comparisons can leave your reviewers ready to sign a contract before they understand how the vendor produces the scores behind hiring decisions.
Assessment science, software and support from one company
Codility is a talent assessment company for hiring across business functions and engineering. Candidates complete business and engineering assessments in Screen, Codility’s assessment platform.
Business roles
AI for Business, Codility’s offer for business roles, runs inside Screen on the same scoring engine as engineering assessments.
Assessment science in house
Codility employs its own assessment science team.
Your talent team works with one company accountable for the scoring, the software and the rollout.

How to evaluate a talent assessment company
Compare the talent assessment companies on your shortlist with the same seven questions.
Bring these seven questions to the kickoff call for your Codility free trial.
- Role coverage. Ask which of your roles the vendor assesses with a realistic task, and which with a questionnaire or a knowledge test.
- Validation documentation. Ask for the documentation behind the scores, and ask who prepared it.
- Adverse impact. Ask for adverse impact analysis at the cut scores you plan to use.
- Scoring consistency. Ask whether the same submission always receives the same score.
- AI policy. Ask how the vendor sets the AI policy for each assessment and records candidate AI use.
- Design support and setup. Ask who helps your team design assessments, and how long setup takes.
- Security and hosting. Ask for the security audit report and the data hosting regions you can choose.
