Canditech and Greenhouse integration: assessments, async video interviews, resume screening, and rollout playbook

Titus Juenemann January 2, 2025

TL;DR

The Canditech–Greenhouse integration brings validated job-simulation assessments, asynchronous video interviews, and anti-cheating signals directly into candidate profiles to streamline screening, reduce time-to-hire, and improve hire prediction. This guide explains what the integration does, which teams benefit most, measurable KPIs, implementation steps, security considerations, and best practices for pilot-to-rollout. The recommended approach is to pilot on a few roles, map assessment outputs to Greenhouse scorecards, monitor completion and outcome metrics, and then expand — combining Canditech simulations with automated resume screening tools like ZYTHR yields the fastest path to saving recruiter time while improving resume review accuracy.

The Canditech integration for Greenhouse connects validated job-simulation assessments, video interviews, and automated pre-screening into your Greenhouse ATS workflow to provide objective, data-driven candidate evaluation. It automates delivery, scoring, and result mapping so hiring teams see assessment outcomes directly on candidate profiles without manual file transfers. This article explains exactly what the integration does, who benefits most, key measurable advantages, implementation steps, and operational best practices so you can decide whether adding Canditech to Greenhouse will improve time-to-hire and hire quality for your organization.

What the Canditech–Greenhouse integration does (at a glance)

  • Automated test invitations Triggers candidate-facing assessments from Greenhouse stages or scorecards and sends invites automatically via email or integrated chatbots.
  • One-click result embedding Displays assessment scores, video responses, and flagged items directly on the Greenhouse candidate page for faster review.
  • Score-to-stage routing Applies pass/fail thresholds and custom rules to auto-advance or filter candidates, reducing manual screening work.
  • Anti-cheat and integrity signals Includes tab-switch tracking, paste detection, webcam snapshots and device/location logs surfaced in Greenhouse for credibility checks.
  • Custom assessments and templates Allows import of Canditech’s validated simulations or custom-built tests (code, SQL, Excel, video) and maps results into Greenhouse fields.

Who needs this integration: hiring teams that run medium-to-large volume hiring, technical roles, or structured competency-based hiring will see the biggest gains. Teams that currently rely on CV screening, screening calls, or manual assessment aggregation benefit most because Canditech adds objective, validated simulation data into your existing Greenhouse workflow. Typical adopters include high-volume talent acquisition teams, technical recruiting teams (software, data, analytics, finance), centralized assessment centers, and organizations scaling campus or bulk hiring where consistent, automated screening improves throughput and reduces mis-hires.

Key measurable benefits for hiring teams

  • Reduce time-to-hire Automating candidate invitations, scoring, and routing can cut the number of screening interviews and shorten time-to-fill by up to 50% in typical implementations.
  • Improve hire-quality predictability Job-simulation assessments are empirically strong predictors of on-the-job performance, reducing the incidence of bad hires and associated replacement costs.
  • Lower recruiter and hiring manager workload Automatic scoring removes manual grading tasks and embeds actionable results in Greenhouse, saving hours per requisition.
  • Scale structured hiring Standardized assessments let teams compare candidates on the same task-based metrics across roles and regions.
  • Increase candidate throughput without sacrificing rigor Chatbot pre-screening plus asynchronous video assessments let you evaluate more candidates in parallel.

Manual screening vs Canditech integrated workflow

Manual process Canditech + Greenhouse
Resume review + phone screen per candidate (manual scheduling) Automated pre-screen and asynchronous assessment invitations from Greenhouse
Subjective interviewer scoring captured in spreadsheets Objective, validated simulation scores and logs visible in candidate profile
Time-consuming interview scheduling and interviewer bandwidth limits Higher candidate throughput using chatbots and on-demand video assessments
Risk of inconsistent task difficulty and scoring Reusable test templates and automated scoring ensure consistency

Assessment types and concrete examples: Canditech supports a broad set of task types that map to common Greenhouse job profiles. Examples include timed coding challenges with test suites, SQL query tasks on realistic datasets, Excel-based modeling or data-cleaning simulations, role-specific job simulations (e.g., customer-service scenario), asynchronous video responses for soft skills, plus cognitive and personality inventories. Each assessment returns granular metrics (accuracy, time-to-complete, rubric-based ratings) that can be used to qualify candidates against role-specific thresholds.

Anti-cheating and integrity features (how they appear in Greenhouse)

  • Tab switch & paste tracking Records if the candidate left the test tab or pasted external content; flags surfaced on the candidate record for reviewer inspection.
  • Device and location logs Shows IP/device fingerprints and geolocation anomalies to detect proxy or suspicious access patterns.
  • Webcam snapshots Periodically captures webcam stills during timed tasks; images and timestamps are attached to the assessment report.
  • Text similarity and content checks Detects likely copy-paste of model answers or AI-generated text and highlights suspicious segments.

Common implementation questions

Q: How long does integration take?

A: A basic integration (API key + mapping of assessments to Greenhouse stages) can be completed in days; a full rollout with custom templates, SSO, and automation rules typically takes 2–6 weeks depending on scope.

Q: Does the integration require extra Greenhouse modules?

A: No additional Greenhouse paid modules are strictly required for basic functionality, but advanced automations may use Greenhouse's custom fields or automation features that some organizations already have in place.

Q: Can results be used in structured scorecards?

A: Yes — Canditech scores can be mapped to custom Greenhouse fields and populated into scorecards to keep hiring decisions centralized and auditable.

Measuring ROI: KPIs to track after integration include time-to-fill, interview-to-offer ratio, assessment completion rate, percentage of candidates advanced without phone screens, and post-hire performance indicators such as 90-day retention or performance scores. Monitor both recruitment efficiency (hours saved per requisition) and outcome quality (hire success rate) to assess whether the assessments are improving prediction and reducing replacement costs.

Best practices for integrating Canditech assessments into Greenhouse

  • Start with pilot roles Pilot 1–3 roles with measurable success criteria to validate cutoffs and candidate experience before wide rollout.
  • Use simulation tasks that mirror day-to-day work Prioritize tasks that replicate actual job responsibilities for stronger predictive validity.
  • Set transparent candidate instructions Provide clear time estimates, allowed resources, and webcam/technical requirements to reduce drop-offs and confusion.
  • Regularly review cutoffs vs performance Adjust thresholds based on hiring outcomes and maintain a cadence for revalidation every 6–12 months.
  • Train hiring managers on how to interpret scores Provide short guides mapping assessment metrics to role competencies and interview focus areas.

Candidate experience and employer branding: Canditech assessments can be branded with company logos, welcome videos, and messaging to create a cohesive candidate experience inside the Greenhouse flow. Asynchronous video and well-designed simulations reduce scheduling friction and improve completion rates; clear branding and instructions also cut technical support tickets and improve perceived professionalism.

Security, privacy and compliance considerations

  • Data storage & region options Confirm where assessment data and webcam snapshots are stored and align settings with your data residency requirements for regions served (e.g., North America, EMEA, APAC, South America).
  • Access control and audit logs Use role-based access in both Canditech and Greenhouse and retain audit trails for who viewed or exported assessment results.
  • Privacy notices & candidate consent Update assessment invitation language to include explicit consent for webcam images, proctoring signals, and data use consistent with local regulations.
  • Integration security Use API keys, IP allowlists, and single sign-on (SSO) where possible; review vendor penetration test reports and privacy policy.

Troubleshooting and operational support

Q: What if candidates don’t complete assessments?

A: Set automated reminders through Canditech, shorten assessment length where possible, and analyze completion rates by role to identify friction points (e.g., mobile incompatibility, unclear instructions).

Q: How are borderline scores handled?

A: Create a manual review queue inside Greenhouse for borderline cases where hiring managers can watch recorded segments or request a live follow-up interview.

Q: Who to contact for integration issues?

A: Leverage Canditech’s developer support and the Greenhouse support page; maintain a Greenhouse admin and a Canditech contact to troubleshoot API or mapping errors.
