Overview

What is Codility?

Codility is software the hiring team operates, with an asynchronous assessment product and a live interview product. Candidates work in a full VS Code environment with a real terminal, package installation and multi-file projects rather than a stripped-back browser editor, on tasks designed using work-sample methodology and reviewed by IO psychologists for fairness and defensibility. Scoring is applied automatically and consistently, and the hiring manager receives a report and interview recording without needing an engineer to grade the submission. A separate product applies the same methodology to an existing workforce for internal mobility rather than hiring.

Features

What are Codility's key features?

Candidates work in VS Code with package installation, a terminal and multi-file projects.

Automated analysis scores code quality, maintainability and complexity, not just whether it passes.

A desktop app detects hidden AI helper tools that screen sharing cannot see.

Every task is tested for how solvable it is by AI, then reviewed by IO psychologists.

Integrity signals aggregate into four risk levels rather than an automatic fail.

Use Cases

How do recruiting teams use Codility?

  • Filter candidates before a technical interview, without an engineer grading each submission
  • Give a candidate real-world tasks in a working development environment, on their own schedule
  • Advance candidates on a code-quality breakdown rather than a pass mark
  • Connect the assessment to the ATS so invites fire on a stage change and scores return to the record
Fit

Who is Codility best for?

  • I need to see how a candidate reasoned through a problem, not just whether they passed
  • In-house teams screening engineers at volume in a full development environment
  • Organisations where security and compliance requirements gate which platforms they can use
Pros & Cons

What are Codility's pros and cons?

Pros

  • Screen and Interview share one task library, so the same content works async and live.
  • Skills Intelligence maps an existing engineering team alongside external hiring.
  • Candidates can use AI coding tools inside the assessment, with interactions captured.
  • Per Codility, assessments are monitored for adverse impact at every cut score.

Cons

  • The entry plan is capped at a fixed annual invite count, unsuitable for recurring volume.
  • Identity verification is limited to the top enterprise plan.
  • Per-candidate allowances mean hiring bursts can trigger unplanned upgrades.
Reviews

What are people saying about Codility?

Engineering and talent teams generally value how little setup a round takes, with a large ready-made question bank and an IDE that works across stacks, which saves the engineering team hours it used to spend building and running tests. The recurring criticism is candidate experience in the newer round types, where the whiteboard and design tools are not self-explanatory and failed test cases are not shown.
