What is Codility?
Codility is a technical skills assessment platform for hiring and evaluating software engineers, offering automated coding tests, live technical interviews and AI-specific tasks such as prompt engineering, used mainly by engineering and technical recruiting teams.
Codility offers three core products: Screen for automated coding tests, Interview for live technical interviews in a shared development environment, and Skills Intelligence for mapping an existing engineering team's capabilities. Task libraries cover general software engineering as well as AI-specific work such as prompt engineering and evaluating AI-generated code. The company was founded in Warsaw in 2009, is headquartered in London with additional offices in Warsaw and San Francisco, and states it serves more than 1,500 customers in 63 countries, including GitHub, SpaceX, Tesla, SAP, Barclays and Citi.
Codility AI features and use cases
- Lets teams turn AI access on or off per assessmentCodility can enable or disable AI tool access for a given assessment, and logs every AI interaction a candidate makes as reviewable activity. Teams can test fundamentals with AI off, then switch it on for later rounds to see how a candidate actually works with AI tools.
- Scores prompt engineering and AI-assisted codingA dedicated task library measures how candidates write prompts, evaluate AI-generated code, and judge when to trust or override a model's output, scored against the COMPASS benchmark for correctness, efficiency and code quality. This gives engineering teams a skills signal for AI-native roles that a generic coding test would miss.
- Flags irregular candidate behavior during testsThe platform combines keystroke analysis, session recording, paste detection and defocus tracking into a four-tier risk assessment instead of a single pass or fail flag. Reviewers get a behavioral signal to investigate rather than an automatic disqualification, which the vendor positions as more defensible than a binary AI-cheating verdict.
- Maps AI and engineering skills across a teamSkills Intelligence applies the same task library to a company's current engineers rather than external candidates, producing a capability map that HR and engineering leaders can use for development planning or reorganization. This extends Codility from a hiring tool into internal workforce assessment.
What sets Codility apart
- Separate task libraries for general software engineering and for AI-native skills such as prompt engineering and AI-code review, instead of one generic coding test.
- Registered legal entity in Germany (Codility Germany GmbH, Berlin) in addition to headquarters in London and an office in Warsaw.
- Starter and Scale plans publish fixed annual prices tied to a number of assessment invites; only the enterprise Custom tier is quote-based.
- Data hosting is offered in the US or in Frankfurt, Germany, as a customer choice rather than one fixed region.

Questions to ask before you buy Codility
Confirm which data hosting region applies to your contract: Codility offers data centers in both the US and Frankfurt, Germany, chosen per customer. Because Skills Intelligence can score a company's own engineers rather than only external candidates, this use can fall under German works council co-determination on monitoring systems (section 87(1) no. 6 of the Works Constitution Act) and needs a GDPR Article 28 processing agreement. Hiring-related use counts as high-risk under the EU AI Act from December 2, 2027.
