TL;DR
Integrating IKM with Greenhouse centralizes validated assessments into your ATS to provide objective, role-aligned skill data at the right stage of the hiring process. The integration automates invites, syncs scores into Greenhouse, and supports standardized evaluation across roles and regions. Implement with a small pilot, map scores to Greenhouse fields, and measure KPIs such as time-to-offer and interview-to-offer conversion to quantify impact. Follow the recommended best practices—targeted tests, calibrated thresholds, clear candidate communication, and secure data handling—to maximize completion rates and hiring accuracy. For teams that want to reduce screening time further, pairing IKM with an AI resume screener like ZYTHR helps prioritize candidates even before assessments are sent.
The IKM integration for Greenhouse connects validated IKM assessments directly into your Greenhouse recruiting workflow so hiring teams can measure technical skills, office skills and role-fit without leaving the ATS. By automating invites, syncing scores into candidate scorecards, and centralizing assessment results, the integration reduces administrative work and surfaces objective data earlier in the pipeline. This article explains how the integration works, who should consider it, the measurable benefits to hiring operations, and practical implementation steps. Read on for technical requirements, best practices, common pitfalls, and a concise ROI checklist so you can decide whether linking IKM to Greenhouse will deliver faster, more accurate hiring decisions for your organization.
What the integration does in practice: after a candidate reaches a configured Greenhouse stage (for example "Screening" or "Take Home Test"), Greenhouse triggers an IKM assessment invite automatically. IKM returns a standardized score and skill breakdown which is mapped into Greenhouse custom fields or scorecards, enabling recruiters and hiring managers to filter and compare candidates using numeric, role-aligned metrics.
Core workflow steps (typical)
- Trigger Greenhouse triggers IKM once a candidate reaches the configured stage or when a user clicks 'Send IKM Assessment'.
- Candidate invite IKM sends an email with secure access to the assessment; invitations include language and time-limit settings.
- Assessment completion Candidate completes the assessment; real-time completion status updates back to Greenhouse via API/webhook.
- Score sync IKM returns raw and normalized scores, competency breakdowns, and suggested pass/fail flags into Greenhouse fields.
- Review Recruiters and hiring managers evaluate candidates in Greenhouse using combined resume, interview notes, and IKM results.

Technical and account requirements
| Requirement | Notes / Action |
|---|---|
| Greenhouse plan & permissions | Admin or developer access to create webhooks or API key; appropriate user roles for mapping scorecard fields. |
| IKM account with API access | Active IKM subscription and API credentials; chosen assessments provisioned for your tenant. |
| Field mapping | Decide which Greenhouse custom fields or scorecard items will store IKM scores and competency breakdowns. |
| SSO & candidate authentication | Confirm SSO requirements for test takers if using enterprise settings; IKM supports single sign-on options for secure access. |
| Regional & language settings | Select assessment language(s) and regional versions supported by IKM for your candidate populations. |
| Data retention & privacy | Agree on storage, retention periods and consent workflows compliant with regulations in target regions. |
Step-by-step implementation checklist
- 1. Define objectives Select which roles and stages will use assessments; set target metrics (time-to-hire reduction, interview pass rate improvement).
- 2. Choose tests Map job profiles to IKM assessments (technical, office skills, personality where relevant) and define pass thresholds.
- 3. Configure Greenhouse Create custom fields/scorecard questions, set webhook/API integration, and establish stage triggers.
- 4. Pilot Run a small pilot (e.g., two roles) to validate workflows, candidate experience, and scoring imports.
- 5. Train users Teach recruiters and hiring managers how to interpret scores and use them alongside resumes and interviews.
- 6. Scale & monitor Expand to more roles, monitor metrics, and iterate thresholds and communication templates based on results.
Best practices to get reliable results include aligning assessments to real job tasks, setting realistic time limits, and avoiding assessment overload (one or two targeted tests per role). Use IKM competency breakdowns to create focused interview guides — e.g., if a candidate scores low on a specific sub-skill, direct the interviewer to probe that area rather than re-testing the same competency in-person. Also, maintain a documented calibration practice: periodically review assessment pass rates against hiring outcomes (performance in role after six months) and adjust cutoffs to balance pipeline volume and quality.
Measuring impact: track a small set of KPIs to validate the integration. Key metrics are time-to-offer, interview-to-offer conversion, candidate drop-off rate after assessment invite, and quality-of-hire signals (first-year performance ratings or ramp time). Compare cohorts before and after integration deployment and run A/B pilots to isolate the effect of assessments from other process changes.
Candidate experience and communication: keep invites concise, include estimated completion time and device/compatibility notes, and offer practice items where possible. Prompt feedback after completion increases candidate satisfaction — IKM supports candidate feedback and summary reports that can be shared if your policy allows it. Clear communication reduces no-shows and improves completion rates.
Common pitfalls and how to avoid them
- Over-testing Requiring multiple long assessments increases dropout — limit tests to essential skills only.
- Uncalibrated thresholds Setting cutoffs without pilot data can exclude suitable candidates — run pilot and review outcomes before enforcing pass/fail gates.
- Poor field mapping If scores are not mapped to the right Greenhouse fields, hiring managers won't see the results when needed — validate mappings during setup.
- Ignoring timezone/language settings Send invites in candidate local time and preferred language to maximize completion; confirm IKM language availability.
Security and privacy considerations: IKM assessments and Greenhouse both require secure API communication, encrypted storage, and consent mechanisms for candidate data. Confirm data residency preferences and retention windows. For regulated roles, ensure assessment data is stored and processed according to applicable regional regulations; IKM provides documentation on privacy that can be referenced in your candidate-facing consent flow.
Sample pilot vs scaled deployment (illustrative)
| Metric | Pilot (2 roles, 3 months) | Scaled (10 roles, ongoing) |
|---|---|---|
| Average completion rate | 78% | 84% (after optimized invites) |
| Interview-to-offer ratio | 10:1 | 6:1 (reduced by early filtering) |
| Time-to-offer | 32 days | 22 days (automation + fewer interviews) |
| First-year retention | Baseline | Improved 8% for roles using assessments |
Comparing approaches to skills assessment
