ATS Integration Quality Varies Wildly
When a video interview platform claims "ATS integration," it can mean anything from a basic Zapier connector to a deep, bidirectional native integration that handles every stage of the interview lifecycle. The difference matters enormously for your recruiting team's daily experience. A shallow integration still requires manual work. A deep one makes the interview platform feel like a native extension of your ATS.
With 82% of companies now using virtual interviews (B2B Reviews, 2025), the integration between your ATS and interview platform has become one of the most critical connections in your HR tech stack. Here is what to look for and how the major platforms compare.
What Makes an ATS Integration Great
Before comparing platforms, let us define the criteria:
- Bidirectional sync: Data flows both ways. Actions in the ATS trigger events in the interview platform and vice versa.
- Real-time updates: Changes propagate in seconds, not hours. Batch syncing creates stale data and delays.
- Stage mapping: Interview stages in the ATS correspond directly to stages in the video platform, with automatic transitions.
- Score visibility: Evaluation scores appear directly in the ATS candidate record, not behind a link to another platform.
- Setup simplicity: Integration should take minutes with an API key, not weeks with a developer.
Greenhouse
Greenhouse offers one of the most mature integration ecosystems in the ATS market. The best video interview integrations with Greenhouse use the Harvest API for bidirectional data sync and the Ingestion API for candidate creation. Look for platforms that map interview stages to Greenhouse stages and push scorecards directly into the candidate profile. StormInterview's Greenhouse integration handles all of this natively, with setup taking under five minutes.
Lever
Lever's integration approach uses a combination of webhooks and their REST API. Strong integrations with Lever automatically create interview stages in opportunities, push completion notifications, and sync evaluation data. The key differentiator is how well the integration handles Lever's unique opportunity-based data model versus the more traditional candidate-centric approach.
BambooHR
BambooHR has expanded its ATS capabilities significantly. Integrations typically use their API to sync candidate data and trigger interview invitations when candidates reach specific stages. Since BambooHR serves primarily small to mid-market companies, the integration needs to be simple enough for teams without dedicated HR tech administrators.
Workable
Workable provides a straightforward API that supports candidate management and stage transitions. Good integrations with Workable automate the invitation process when candidates enter the video interview stage and push results back as evaluation entries. Workable's API is well-documented, which means integrations tend to be reliable.
The Scheduling Factor
One area where integrations often fall short is scheduling coordination. Cronofy (2024) found that 42% of candidates drop out due to scheduling difficulties. The best ATS integrations for async video interview platforms sidestep this entirely by removing scheduling from the equation. Candidates get an invitation link and complete the interview on their own time. No calendar coordination needed.
This is a fundamental advantage of async over live interview platforms when it comes to ATS integration. There are fewer moving parts, less coordination required, and fewer points of failure.
