The ASTRNT integration for Greenhouse combines AI-powered structured video interviews and targeted skill validation directly into your ATS flow, enabling consistent, scalable early-stage screening. For teams using Greenhouse, this integration reduces scheduling overhead, standardizes candidate evaluation, and provides objective data to inform hiring decisions. This article explains what the integration does, who benefits most from it, and measurable advantages to expect. You’ll find setup considerations, recommended workflows, KPI examples, and a practical comparison versus manual screening so you can decide whether to adopt it in your hiring process.
What the ASTRNT + Greenhouse link delivers is automation of two early hiring activities that commonly create bottlenecks: initial interviewer consistency and skills validation. ASTRNT’s tools slot into Greenhouse so that invites, candidate submission of video responses or tests, and automated scoring flow back to the candidate’s Greenhouse profile without separate tracking or duplicate data entry. That architecture matters because it preserves the recruiter and hiring manager experience inside Greenhouse while adding structured artifacts (scored interview responses, assessment results, role-specific pass/fail indicators) that make later-stage decisions faster and more evidence-based.
Core features of the integration
- AI Structured Video Interviews On-demand, standardized interviews where candidates record answers on any device. No logins or downloads required; responses are auto-attached to the Greenhouse candidate record.
- Skill Validation Assessments Behavioral, situational and technical tests tailored to role requirements. Choose from ready-to-use templates or create custom assessments.
- Automated Scoring & Fairness Controls ASTRNT applies consistent scoring logic across candidates; scoring metadata is visible in Greenhouse to support auditability.
- Seamless ATS Workflow Invites, reminders and results flow back into Greenhouse stages so recruiters don’t need separate dashboards.
- No setup fees & Dedicated Support Greenhouse users can onboard without upfront platform fees and get implementation assistance for configuration and question design.

Who should evaluate this integration
- High-volume hiring teams Companies screening large applicant pools (campus, early-career, high-turnover roles) benefit from automated early-stage filtering.
- Technical hiring teams Teams that need objective verification of practical skills (coding, data tasks, role simulations) to avoid false positives from resume claims.
- Distributed or remote hiring Organizations interviewing candidates across time zones or with limited recruiter bandwidth gain from asynchronous, on-demand screening.
- Hiring managers prioritising consistency Groups that want standardized evaluation rubrics to reduce variability between interviewers and improve comparability of candidates.
Key benefits go beyond convenience: the integration reduces calendar coordination cost, shortens time-to-hire in the early pipeline, and increases the signal available to hiring decisions. Automated scoring and structured responses produce comparable metrics across candidates that decision-makers can use to rank or screen objectively. For operational teams, fewer manual screening hours and less interviewer variance translate into predictable throughput. For candidates, the on-demand model usually increases completion rates and offers a transparent, repeatable experience that supports employer brand.
How ASTRNT complements common hiring stages
| Hiring Stage | How ASTRNT Enhances It |
|---|---|
| Application Screening | Auto-invite qualified applicants to a short video screening or skills test; results attach to Greenhouse profile to triage next steps. |
| Phone/Initial Interview | Replace or augment live phone screens with structured video questions that standardize prompts and capture consistent evidence. |
| Technical Assessment | Deliver role-specific technical tasks with automated scoring and human review flags for deeper evaluation. |
| Panel / Final Interviews | Provide panel members with objective assessment reports, reducing time needed for alignment meetings. |
Implementation checklist (practical steps)
- Define role-specific competencies Map must-have skills and behaviors for each role so assessments and interview prompts align with hiring criteria.
- Select assessment templates Start with ready-to-use tests for common roles and customize only where necessary to preserve scalability.
- Configure Greenhouse stage triggers Set which Greenhouse stage auto-sends an ASTRNT invite (e.g., after resume screen or application).
- Set scoring thresholds Decide pass/fail or gating cutoffs and how scores map to next-stage actions in Greenhouse.
- Pilot and calibrate Run a short pilot (20–50 candidates) to validate scoring alignment with human interviewers and adjust prompts or cutoffs.
Measuring impact requires selecting a few KPIs and measuring baseline performance before rollout. Core KPIs include completion rate of assessments, time-to-offer for screened candidates, false positive rate (candidates advanced who fail later-stage interviews), and recruiter hours saved per hire. Track these over a three-month window after pilot to quantify improvement. Example calculation: if ASTRNT reduces initial screening time by two hours per hire and a recruiter handles 50 hires/year, that’s 100 hours saved annually. Multiply by average recruiter fully-burdened hourly cost to estimate direct saving; add faster time-to-offer benefits (reduction in vacancy days) to compute total ROI.
Sample structured interview prompts & assessment types
- Situational judgment Provide a short scenario relevant to the role and ask candidates to choose or rank responses; useful for customer service and operations roles.
- Behavioral STAR prompts Ask candidates to describe a specific Situation, Task, Action and Result to evaluate past behaviour on competencies like teamwork or ownership.
- Role-specific technical tasks Coding challenges, spreadsheet modelling, or data interpretation tasks scored for correctness and approach.
- Communication assessment Timed prompts that measure clarity, structure and ability to present ideas concisely—useful for client-facing roles.
Security and privacy are essential for any third-party integration. ASTRNT provides privacy documentation and has regional considerations for APAC customers; data from interviews and assessments is stored and linked to candidate records in line with platform policies. Review ASTRNT’s privacy policy and Greenhouse support page for specific data retention, export controls, and access logs to satisfy internal compliance requirements.
Common troubleshooting and support tips
- Candidates can’t access the assessment Confirm the auto-invite link timing in Greenhouse and check that candidate email addresses are correctly formatted; ASTRNT supports no-login access, so link delivery is the typical issue.
- Video recordings not attaching Verify API connectivity in the Greenhouse partner settings and review webhooks; reach out to ASTRNT support if webhook retries show errors.
- Scoring discrepancies Run a calibration sample where human reviewers score the same set of submissions and compare to automated scores to locate incongruent prompt wording or rubric misalignment.
- Language or accessibility concerns ASTRNT supports English and Portuguese; plan for translations or accommodations for other languages or accessibility needs during rollout.
ASTRNT + Greenhouse vs Manual Screening
