Cactus + Greenhouse integration: Task-based assessments and AI interview simulations to speed screening for sales and high-volume hiring

The Cactus integration for Greenhouse connects job-specific, real-world assessments and AI-driven interview simulations directly into your applicant tracking workflow. Instead of relying on generic personality questionnaires, Cactus enables hiring teams to assign tasks that mirror actual on-the-job work and see results inside Greenhouse where decision-makers already evaluate candidates. This guide explains how the integration works, which teams and company sizes get the most value, measurable benefits, implementation steps, practical best practices, and troubleshooting tips so you can evaluate whether Cactus + Greenhouse should become part of your hiring stack.

What the integration does: it automates invite and result flows between Greenhouse and Cactus, surfaces assessment scores and AI-simulation summaries in the candidate profile, and allows stage gating based on performance thresholds. The integration reduces manual steps for recruiters and provides hiring managers with structured, job-relevant evidence to compare applicants.

How the Cactus → Greenhouse candidate flow typically works

• Invite From Greenhouse a recruiter or an automated stage action sends a Cactus assessment invite to a candidate using the integration; the candidate receives a branded email with instructions.
• Assessment Candidates complete a job-specific task or an AI-driven interview simulation (e.g., sales cold outreach roleplay, customer success escalation handling) hosted in Cactus.
• Results sync Cactus automatically posts scores, sub-scores, and a concise narrative summary back to the candidate’s Greenhouse profile and activity feed.
• Decision Hiring teams use these objective artifacts in Greenhouse to gate moves to interview stages, share feedback, and compare candidates side-by-side.

Who benefits most from integrating Cactus with Greenhouse

• Sales and Customer-Facing Roles Teams hiring for quota-bearing or client-interfacing roles gain high signal from AI roleplay simulations that reproduce real conversations and objection handling.
• High-Volume Hiring Recruiting teams that screen hundreds or thousands of applicants can standardize evaluations and remove manual grading bottlenecks.
• Small HR Teams at Fast-Growing Companies Organizations without a large interview panel get actionable evidence early to prioritize the most promising candidates.
• Technical or Task-Oriented Job Openings Roles where practical tasks predict on-the-job success (e.g., product support triage, content editing, data entry workflows) benefit from real-work assessments.

Cactus (real-world assessments) vs Traditional Personality Tests

Key measurable benefits organizations report after integrating Cactus with Greenhouse include faster screening cycles, higher confidence in interview shortlists, and reduced time spent on low-signal screening activities. Typical metrics you can track: average time-to-screen, percentage of screened candidates progressing to on-site interviews, and hiring manager satisfaction with candidate readiness.

Setup and implementation checklist

• Account mapping Ensure your Cactus and Greenhouse admin accounts are provisioned and linked; confirm user roles for recruiters and hiring managers.
• Assessment templates Create job-specific tasks and AI-simulation scripts in Cactus aligned to your competency framework.
• Greenhouse integration settings Enable the Cactus integration in Greenhouse, configure stage triggers, and set the desired fields to receive score data.
• Automation rules Define pass/fail thresholds or score-based tags that automatically advance or flag candidates for review.
• Pilot and calibrate Run a short pilot with live candidates, collect feedback, and adjust scoring rubrics. Note: Cactus lists no partner implementation fee in standard documentation—confirm with your provider for custom setups.

Supported roles and sample assessment types

Best practices for using Cactus assessments inside Greenhouse

• Define job-critical competencies first Map each assessment to 2–4 competencies that matter most for job success so scoring is focused and comparable across candidates.
• Calibrate graders If human review supplements AI scoring, ensure reviewers use a shared rubric and a short calibration set to limit variability.
• Use pass/fail gates thoughtfully Set thresholds that remove only clear mismatches—avoid overly strict cutoffs that eliminate potentially trainable candidates.
• Combine evidence Use Cactus results together with resume data, reference checks, and interviews rather than as the sole hiring determinant.

Monitoring and troubleshooting: track integration health by monitoring failed webhooks, incomplete assessment rates, and candidate support tickets. Common fixes include re-authenticating the API connection in Greenhouse, checking field mappings, and verifying that Cactus project keys haven't been rotated.

Example scenario: A mid-market SaaS company hires five SDRs per quarter. After integrating Cactus with Greenhouse and running a single-quarter pilot, they reduced initial interview scheduling by 40% (fewer low-signal candidates invited) and shortened time-to-offer by two weeks for successful hires because hiring managers received standardized task results in Greenhouse and could prioritize top performers. These are representative outcomes—your results will vary based on role complexity and volume.
