TL;DR
CalendarHero's Greenhouse integration streamlines interview scheduling by enabling self-service booking, auto-inserting conferencing links, sending meeting briefings, and logging all scheduling activity back into Greenhouse. The result is measurable time savings, fewer reschedules, and cleaner audit trails — especially valuable for high-volume or distributed hiring teams. The guide covers core features, supported conferencing providers, setup steps, rollout checklists, common troubleshooting scenarios, and security considerations. Conclusion: when combined with systematic screening (for example using AI tools to rank resumes before scheduling), CalendarHero helps recruit faster and reduces administrative overhead across the hiring process.
CalendarHero's Greenhouse integration automates interview scheduling across the recruiting funnel so recruiters, coordinators, and hiring managers spend less time coordinating and more time engaging candidates. It connects candidate data, calendar availability, conferencing links, and Greenhouse activity logs to create a single, repeatable workflow for interviews. This article explains what the integration does, which teams benefit most, implementation steps, measurable benefits, and practical best practices for rolling it out at scale. Read on for examples, setup notes, and troubleshooting tips to decide if CalendarHero plus Greenhouse fits your hiring operations.
What it does in practice: CalendarHero lets recruiters share real-time availability via email or LinkedIn, lets candidates self-book 1:1 and group interviews, auto-populates video conferencing links, sends meeting briefings with Greenhouse candidate data, and logs meeting events back to Greenhouse automatically. The integration reduces manual calendar edits, duplicate data entry, and scheduling friction that typically slows time-to-hire.
Core features of the CalendarHero + Greenhouse integration
- Self-service booking Embed availability links in outreach so candidates can pick interview times without back-and-forth emails.
- Automated conferencing links Calendar events auto-include Zoom, Google Meet, Teams, Webex, or other configured providers.
- Greenhouse activity logging Meeting requests, confirmations, declines and notes are logged on the candidate's Greenhouse activity feed.
- Meeting briefings Receive candidate context (stage, resume snapshot, custom scorecards) in meeting notifications delivered to Gmail, Outlook or Slack.
- Group interview algorithm Intelligent scheduling finds times that satisfy multiple interviewer calendars and reduces reschedule cycles.

Supported conferencing and calendar providers
| Provider | Notes |
|---|---|
| Zoom | Auto-creates meeting links and includes dial-in info; supports host assignment and passcodes. |
| Google Meet | Works with Google Calendar events and Google Workspace accounts for automatic link insertion. |
| Microsoft Teams | Adds Teams links for Microsoft 365 calendars; syncs organizer identity to prevent permission issues. |
| Cisco Webex | Includes Webex links and supports enterprise Webex accounts via API integration. |
| Other (via URL) | Custom conferencing URLs are supported for vendors that don't have a native connector. |
How the integration works — step-by-step: After authenticating CalendarHero with Greenhouse and your calendar provider, the integration reads candidate and interview stage data. When a recruiter offers availability or a candidate books a slot, CalendarHero creates the calendar event, inserts the conferencing link, sends confirmations and reminders, and writes the relevant activity back into Greenhouse for auditability. Optional meeting briefings are generated from candidate records so interviewers have context without manual prep.
Key measurable benefits (real-world examples)
- Time saved per interview Teams report saving 8–20 minutes per interview by eliminating email exchanges, manual calendar updates and logging.
- Faster candidate response Self-booking reduces scheduling drop-off because candidates can secure times at peak interest — improving show rates.
- Fewer scheduling conflicts Intelligent group scheduling reduces reschedules for multi-interviewer panels by finding optimal overlapping availability.
- Improved data hygiene Automatic logging to Greenhouse ensures the audit trail is complete and consistent for compliance and reporting.
Common Greenhouse activities logged by CalendarHero
| Activity | How it's recorded |
|---|---|
| Meeting requested | Creates an activity entry on candidate profile with timestamp, organizer, and proposed times. |
| Meeting confirmed | Logs event confirmation, calendar invite details and conferencing link in the activity feed. |
| Meeting declined or rescheduled | Records decline reason and new proposed options so recruiters can track outcomes. |
| Meeting notes | Key meeting outcomes can be appended to the activity feed automatically or by interviewer input. |
Setup and prerequisites: Administrators need Greenhouse user permissions to install integrations, access to the organization calendar(s) to enable availability sharing, and API credentials if your conferencing provider requires them. Verify domain-level settings (for Google Workspace or Microsoft 365) to allow third-party calendar writes. CalendarHero provides a Get Started Guide to walk through authentication, default event templates and activity mapping to Greenhouse stages.
Rollout checklist for a smooth deployment
- Map interview types Define which Greenhouse stages will trigger CalendarHero (phone screen, onsite, technical).
- Standardize interview templates Create event templates with consistent durations, buffer times and conferencing defaults.
- Train recruiters and coordinators Run a short workshop showing booking links, editing events, and where activity appears in Greenhouse.
- Monitor first 30 days Track scheduling time, reschedule rate, and any missed logs to tune settings.
- Adjust permissions and reminders Set reminder cadence and ensure interviewers receive briefings via their preferred channel (email or Slack).
Common questions about CalendarHero + Greenhouse
Q: Does CalendarHero change candidate data in Greenhouse?
A: No — CalendarHero reads candidate and stage data to create context for scheduling. It writes meeting-related activities and notes but does not overwrite core candidate fields unless configured to update a specific custom field.
Q: Can candidates book without creating a Greenhouse candidate record first?
A: Best practice is to link bookings to existing Greenhouse candidates. CalendarHero can support bookings that create a new candidate record if you enable that flow, but the preferred flow is to schedule after the candidate is in Greenhouse to maintain data integrity.
Q: How are time zones handled for global teams?
A: CalendarHero displays availability in the candidate's local time based on browser settings and converts calendar invites to participants' local time zones to prevent confusion.
Q: What happens when an interviewer cancels?
A: CalendarHero notifies stakeholders, logs the cancellation in Greenhouse, and can present alternate times or trigger an automated reassign workflow depending on your configuration.
Q: Is there auditability for compliance?
A: Yes — every scheduling action is recorded in Greenhouse activity so recruiters and auditors can trace when meetings were proposed, accepted, or modified.
Troubleshooting and support tips: If calendar events don't appear, verify that the connected calendar account has write permissions and that CalendarHero is authorized for that calendar. For missing conferencing links, check provider API quotas or credential rotations (especially with enterprise Zoom or Microsoft tenants). Use the CalendarHero logs to trace API responses; support teams typically resolve misconfigurations within one business day.
Security and operational considerations
- Permission scoping Grant minimum permissions required: calendar write access and read access to candidate stage data. Avoid broad admin tokens unless needed for automation.
- Data retention Activity logs in Greenhouse persist per your org settings — confirm retention policies for meeting notes and recordings.
- Single sign-on and SSO Use SSO for CalendarHero and conferencing providers where possible to centralize access control and reduce credential drift.
- Audit trail Leverage the automatic activity entries for operational audits and SLA tracking for interview scheduling SLAs.
