By automating initial candidate interactions, businesses can focus on high-value tasks and enhance the candidate experience. This guide will walk you through the integration process, highlighting specific benefits and providing actionable steps to implement AI phone screening effectively.

Prerequisites for Successful Integration

Before diving into the integration process, ensure you have the following prerequisites in place:

1. Greenhouse Account: An active Greenhouse ATS account with admin access.
2. NTRVSTA Account: A registered account with NTRVSTA for AI phone screening.
3. Technical Resources: Access to a developer or technical resource familiar with API integrations.
4. Time Estimate: Most teams complete this integration in 2-3 business days.

Step-by-Step Integration Process

Step 1: API Access

Begin by obtaining the API keys from both Greenhouse and NTRVSTA. This will allow for seamless communication between the two platforms.

Define the screening parameters in the NTRVSTA platform, such as the questions to be asked and the scoring criteria for candidates.

Expected Outcome: A tailored screening process that aligns with your company's hiring standards.

Step 4: Test the Integration

Conduct test runs using dummy candidates to ensure that the integration functions as intended. Verify that candidate responses are recorded accurately in both systems.

What You Should See: Successful test calls and data flowing correctly into Greenhouse.

Step 5: Launch and Monitor

Once testing is complete, launch the integration to live candidates. Monitor the initial results closely to gather feedback.

Expected Outcome: Enhanced candidate experience with reduced screening time, ideally from 45 minutes to just 12 minutes.

Troubleshooting Common Issues

1. API Key Errors: Ensure that the correct keys are used and that permissions are set appropriately.
2. Webhook Failures: Check the webhook URLs for accuracy and ensure they are live.
3. Data Sync Issues: Verify that both systems are configured to handle the same data formats.
4. Candidate Drop-off: Monitor completion rates; if below 95%, consider adjusting the screening questions.
5. Integration Latency: If there are delays, assess server response times and consider optimizing your API calls.
