What it is

CodePair by CodeSubmit runs live coding interviews in a browser-based shared IDE, terminal, and repository. Hiring teams can observe how candidates write code and collaborate in an engineering-style project. Candidates may use ChatGPT, Claude, Gemini, and coding-agent workflows, while reviewers see prompts, responses, actions, and accepted edits. The terminal provides bash or zsh, Nix packages, language runtimes, PostgreSQL, and Redis. CodePair says reproducible Nix environments cover more than 100 languages and 1,000 packages and services. Git history, branches, shared commits, pull-request simulation, diffs, merge-conflict resolution, and GitHub or GitLab repositories support repository work. Automatic port detection, live reload, concurrent services, database connections, and preview links support running projects. Integrations include Greenhouse, Lever, Personio, Ashby, Zapier, Slack, and an Enterprise API. Plans start at $49 a month, billed monthly, with a seven-day trial.
