Send validated assessments to candidates from Greenhouse — without leaving the job stage.

In brief

Greenhouse customers add JobCannon as an Assessment Partner from their integration settings. Once configured at a job stage, the recruiter clicks "Send Assessment" on a candidate — Greenhouse calls JobCannon's send_test endpoint, the candidate receives a co-branded email, completes the assessment, and the score (with full result envelope) is returned to Greenhouse via the test_status endpoint and the partner-supplied callback URL. The integration uses Basic Auth credentials provisioned per organisation, supports sandbox testing without polluting the hire pipeline, and works with any of the 22 hire-eligible tests in the JobCannon library (Big Five, DISC, EQ, integrity, cognitive ability, conflict styles, etc.). Test scores are normalised through the standardised result envelope so your Greenhouse scorecard renders the same shape regardless of which test ran.

How it works

From Greenhouse admin to first scored candidate.

1. 1

   Add JobCannon as an Assessment Partner in Greenhouse

   Greenhouse admin → Configure → Dev Centre → Integrations → Assessment Partners. JobCannon issues your organisation Basic Auth credentials (sandbox first, then production).

2. 2

   Pick assessments + assign to job stages

   Choose from 22 validated tests (Big Five, DISC, EQ, integrity, etc.). Drop each onto the appropriate stage in the Greenhouse pipeline.

3. 3

   Recruiter sends to candidates

   On the candidate page, recruiter clicks "Send Assessment". Greenhouse calls JobCannon, JobCannon emails the candidate (co-branded with your org name).

4. 4

   Candidate completes (sub-1s scoring)

   Candidate takes the assessment in their browser; scoring is computed in under a second. JobCannon stores the standardised result envelope.

5. 5

   Score returned to Greenhouse

   JobCannon PATCHes the partner callback URL with status=complete + score envelope. Greenhouse displays it on the candidate scorecard and can auto-advance the application.

Why teams pick JobCannon for Greenhouse

• 56 hire-relevant assessments — Big Five, DISC, EQ, IQ, integrity, cognitive ability, conflict styles — validated against published psychometric standards, not vendor-curated.
• Multi-tenant org isolation by design — each customer's candidates are isolated at the row level (RLS), so the same adapter serves Greenhouse, Ashby, Lever and Workable from one codebase.
• Sub-1s scoring + standardised result envelope — every assessment returns the same shape (dimensions[].score) so your ATS can rank candidates without provider-specific glue.
• Sandbox + production environments — credentials with `is_sandbox` flag let your team run end-to-end test cycles without polluting hire pipelines.
• EU-resident data + GDPR-ready DPA — assessments and PII stay on EU Supabase, retention defaults to 90 days with org-level override.

56 validated assessments, multi-tenant org isolation, sandbox + production environments, sub-1s scoring, REST + webhook delivery. Free for sandbox + first 5 invitations/mo. From $99/mo on the Business tier; partnership engagements scope white-label and higher rate limits.
