TL;DR
The CodeSignal integration for Greenhouse streamlines technical hiring by enabling prescreens, Certified Evaluations, live coding interviews, and recorded sessions to be managed and reviewed inside Greenhouse. It benefits high-volume hiring teams, recruiters, hiring managers, and L&D by increasing throughput, standardizing evaluation, and centralizing artifacts. Practical setup involves API pairing, mapping assessments to job templates, defining thresholds, and training interviewers. Track metrics such as time-to-hire, screen-to-interview conversion, and quality of hire to validate impact. In conclusion, the integration reduces manual work and provides consistent, objective assessment data — and when combined with AI resume screening tools like ZYTHR, teams can further cut screening time and raise resume review accuracy.
The CodeSignal integration for Greenhouse connects technical assessments, live coding interviews, and evaluation data directly into your applicant tracking workflow. It centralizes candidate invites, recorded interview sessions, and scored results so hiring teams can move from screening to interviewing with fewer manual handoffs. This article shows how the integration works, which hiring and L&D teams get the most value, and the practical benefits you can expect — including configuration tips, sample workflows, and metrics to track after rollout.
What the integration does: CodeSignal's Greenhouse integration allows recruiters and hiring managers to send CodeSignal Pre-Screens and Certified Evaluations from within Greenhouse, receive completion notifications, view a summarized scorecard in each candidate's Greenhouse profile, and generate collaborative interview links for live sessions that can be recorded and replayed. Results and artifacts remain attached to the candidate record so decisions are traceable and centralized.
Typical hiring workflows using the integration
- Automated prescreen step Trigger a CodeSignal Pre-Screen from Greenhouse when a candidate reaches the phone-screen stage; results populate the candidate's profile and notify the recruiter and hiring manager.
- Structured on-site simulation Invite shortlisted candidates to a Certified Evaluation; use expert-created, role-specific assessments to produce objective scores that inform interview selection.
- Collaborative live interview Generate an interview link in Greenhouse, run a live coding session in CodeSignal, and attach the recorded session to the candidate record for later review by interviewers who missed the live call.
- Decision and feedback Combine CodeSignal scores and Greenhouse interview feedback in one place to make faster, data-driven hiring decisions, and to share consistent feedback with candidates.

Manual screening vs. CodeSignal + Greenhouse
| Dimension | Manual screening | CodeSignal + Greenhouse |
|---|---|---|
| Candidate throughput | Limited by recruiter/interviewer time and manual scheduling | Higher throughput with automated prescreens and centralized invites |
| Evaluation consistency | Variable—depends on interviewer and format | Standardized Certified Evaluations with expert-backed rubrics |
| Traceability | Scattered notes, emails, and files | Assessment scores and recorded sessions attached to candidate profiles |
| Time to decision | Longer due to manual tasks and coordination | Shorter due to instant notifications and in-platform scoring |
Key practical benefits: speed and accuracy. By centralizing assessment invites and results in Greenhouse, organizations reduce administrative steps (fewer emails, no manual score entry) and accelerate the screening funnel. Objective, certified assessments provide repeatable scoring criteria that improve comparability between candidates and reduce ambiguous pass/fail judgments during early stages.
Implementation checklist (practical setup steps)
- Configure API/linking Connect your CodeSignal and Greenhouse accounts using the integration keys; verify that webhooks are enabled so completion notifications push to Greenhouse.
- Map assessments to job templates Decide which Pre-Screens and Certified Evaluations map to each role in Greenhouse and set the default assessment per job posting.
- Define pass thresholds Establish score thresholds and rubric interpretations for automated routing (e.g., proceed to onsites, invite to interview, or decline).
- Train interviewers Show interviewers how to view CodeSignal scorecards, replay recorded sessions, and where to add feedback in Greenhouse.
- Monitor and iterate Track funnel metrics and adjust assessments or thresholds based on hire quality and false positives/negatives.
Assessment types and result artifacts visible in Greenhouse: Pre-Screens for rapid filtering, Certified Evaluations for validated role assessments, and collaborative live interviews with recording. In Greenhouse you typically see a summary score, a breakdown by skill area (e.g., algorithms, system design, debugging), pass/fail flags, and links to recorded sessions and full evaluation reports stored by CodeSignal.
Common questions about the integration
Q: How long does setup take?
A: Basic setup — API pairing, mapping a few assessments, and enabling notifications — can be completed in a day for teams with existing admin access. Larger organizations implementing custom rubrics or workflow automation may take 1–3 weeks to fully validate.
Q: Is there an implementation fee?
A: According to the integration details, there is no partner implementation fee for the CodeSignal–Greenhouse integration, though enterprise contracts or custom services could be priced separately.
Q: Where are recordings and results stored?
A: Recorded sessions and detailed reports are maintained by CodeSignal and linked within the candidate's Greenhouse profile. Review CodeSignal’s privacy policy for data retention specifics and Greenhouse support pages for ATS storage handling.
Q: Can I customize assessments for different roles?
A: Yes. CodeSignal offers role-specific Certified Evaluations and you can assign different assessments to job templates in Greenhouse to match role expectations.
Best practices for evaluation and threshold setting
- Start with validated Certified Evaluations Use expert-created tests as a baseline before creating custom assessments; they provide reliable scoring and are maintained by CodeSignal.
- Set conservative thresholds and iterate Begin with thresholds that favor inclusion for interviews, then tighten as you correlate scores with on-the-job performance.
- Combine quantitative and qualitative input Use CodeSignal scores alongside interview notes in Greenhouse to capture context that pure scores might miss.
- Log decisions and outcomes Track candidate sources, assessment scores, and hire outcomes to validate assessment effectiveness over time.
Using the integration for L&D and upskilling: Beyond hiring, CodeSignal assessments integrated into Greenhouse can support internal mobility and training validations. L&D teams can assign assessments to employees, collect baseline skill scores, and use re-assessments to measure progress after training modules or mentorship.
