How does Codility assess software engineers?

Engineers work on real-world coding tasks in a VS Code environment, with the full Claude Code and Codex in the terminal when you allow them. Screen, Interview and Skills Intelligence cover engineering hiring and development, with 1,300+ validated tasks across 80+ languages and frameworks. Assess engineering skills

Do non-technical hiring teams need engineering to run a business assessment?

No. Business hiring teams scope the assessment with functional leaders and their governance reviewers. Engineering involvement is welcome and never required.

How long does a business assessment take?

Business tasks run 5 to 60 minutes. Short general tasks of 5 to 15 minutes work for any role. Each asks for one deliverable, so the candidate's time goes into the work.

Are we measuring AI skill or general analytical skill?

The task asks for a deliverable produced with the assistant, so the result reflects how the candidate directed the assistant, checked its output and used the source files. The prompts show that work. Reviewers see the deliverable and the prompts together.

Every new hire now works with AI. Your hiring process still can’t show who does it well.

01

Every candidate lists AI tools on the résumé, and an interview answer about AI proves little about real work.

02

Your engineers now use AI to write code, and a test that doesn’t allow AI checks a job that no longer exists.

03

Each function’s hiring managers judge AI skill their own way, if they judge it at all.

Assess business roles on real tasks

Use general tasks for any role or role-tailored tasks. Coverage includes sales, marketing, finance, operations and customer roles. Each task runs 5 to 60 minutes and asks for a real deliverable: a customer email to answer, a report to check, a recommendation to make.

Screen for business roles

See how business candidates used the assistant

Candidates read the brief, check the source files and work with the assistant on a deliverable. Some tasks plant errors for them to catch.

Standardize the hiring step

Use Screen to collect the evidence before the interview. Agree the criteria once with each function’s hiring managers, then use them for every open role in that function. Recruiters get results in their applicant tracking system.

Extend to employee development

Use Skills Intelligence to measure a business team’s practical AI skills today and plan training where they need it. Engineering teams use the engineering assessments on the same platform.

Evidence from real work grounded in assessment science

Knowing the names of AI tools says little about using them well. A knowledge quiz checks recall. A training dashboard shows who attended. A real job task shows how someone checks the source material, uses the assistant and produces a result.

AI for Business runs on the same assessment platform as engineering assessment, with the same scoring, reporting, integrations and security posture.
