Candidate Code vs Codility

Candidate Code manages take-home coding challenges for technical recruitment. Teams upload a challenge with one git push and send it to a candidate with one click. The service creates a fresh repository for each candidate that supports anonymous cloning. Candidates use their own operating system, IDE, and runtime tools without creating an account on the service. Hiring teams can inspect commits and diffs, discuss submissions in comment threads, and rate them with five stars. Email alerts can notify reviewers when a candidate starts or finishes a challenge. The homepage offers the first 10 challenges free with no time limit. Starter costs $27 a month for up to five challenges monthly and 10Mb repositories. Business costs $195 a month for up to 50 challenges monthly and 100Mb repositories. Candidate Code is available on the web or self-hosted. Terms prohibit repositories containing more than 50 megabytes. Registered-account support is provided by email.
