Hiring often feels disjointed. Recruiters spend most of their time in an applicant tracking system (ATS), while hiring managers evaluate candidates in a separate assessment platform. Because these systems don’t always sync smoothly, teams end up manually transferring candidate data, statuses, and test results between tools—wasting time and increasing the risk of errors.
By bridging the gap between your assessment tools and your core HR platforms, recruiting teams can accelerate the hiring pipeline, reduce administrative drag, and improve the candidate experience.
This guide outlines how CodeSignal connects with your existing hiring stack. You’ll learn about the key platforms CodeSignal integrates with, how data flows between them, and what factors to consider when evaluating a skills testing platform’s integration capabilities.
CodeSignal integrates with a wide ecosystem of applicant tracking systems, learning management systems, identity providers, and scheduling tools. Important ATS integrations include Greenhouse, Lever, iCIMS, Workday, SmartRecruiters, Ashby, JazzHR, Workable, SAP SuccessFactors, and LinkedIn Talent Hub. These connections allow recruiting teams to trigger assessments, sync candidate data, and route results directly within the tools they already use—without switching platforms.
Why do integrations matter in hiring?
When software development teams are in the assessment stage, efficiency matters. A major hurdle in hiring is the cost of context-switching across disconnected tools.
If a recruiter has to copy a candidate’s email from the ATS, log into the assessment platform, create an invitation, and then manually copy the final score back to the ATS, the hiring process can grind to a slow halt.
Disconnected assessment data also creates blind spots in candidate decision-making. Hiring managers and recruiters need a single source of truth to review a candidate's progress. Without specific permissions, hiring managers might review an outdated resume, or recruiters might miss a completed test score.
Big picture: Ultimately, skills testing platforms without ATS integrations slow pipelines down instead of accelerating them. When properly integrated, the recruiter experience improves dramatically. You can trigger assessment invitations, view status updates, and route final results to the correct stakeholders without ever leaving the ATS.
How your CodeSignal account integrations work
As a CodeSignal admin, you have several ways to connect to your existing tools and ensure that data moves securely and automatically.
At the core of these connections is the data flow. When connected, platforms automatically share essential information like candidate records, assessment invitations, final scores, and completion statuses. This keeps candidate profiles updated in real-time.
CodeSignal supports native, out-of-the-box integrations with major platforms and requires minimal configuration to make the hiring magic happen.
Finally, if organizations need specific tools, CodeSignal offers a “request new integration” option to help expand the ecosystem.
CodeSignal's ATS Integrations: Top Platforms
The most critical integrations for any technical hiring team are those that connect with the applicant tracking system. Here is a closer look at the key ATS platforms.
Greenhouse
Greenhouse is a leading hiring operating system used by thousands of companies to design and automate their recruitment processes.
Recruiters can trigger a CodeSignal assessment directly from a specific candidate stage within Greenhouse. Once the candidate completes the test, CodeSignal syncs the score and detailed results back to the candidate’s profile.
This integration ensures that all CodeSignal assessment data, including CodeSignal assessment outcomes, is stored and easily reviewed within the candidate’s profile. The connection allows recruiters and hiring managers to access centralized information and make informed hiring decisions in one central place.
Lever
Lever is another popular talent acquisition suite and recruiting platform that combines ATS and CRM functionality. It’s designed to help teams source, nurture, and manage candidates throughout the entire hiring lifecycle.
You can send a Codesignal test and have the assessment result from the CodeSignal test automatically linked to the candidate’s opportunity record. This step provides a direct link for recruiters to review the assessment outcome.
The Broader ATS Ecosystem
Beyond Greenhouse and Lever, CodeSignal connects with a variety of other applicant tracking systems to support companies of all sizes. Regardless of your hiring goals, the purpose is to help you go beyond a general coding assessment and into a full-scale recruitment cycle.
Here’s a quick look at some of the other options available on CodeSignal’s integrations marketplace:
- iCIMS: An enterprise talent cloud built for large-scale recruiting and complex hiring workflows.
- Workday: A massive enterprise HCM with robust ATS functionality, highly common in Fortune 500 environments.
- SAP SuccessFactors: Comprehensive HR suite offering deep enterprise ATS capabilities.
- SmartRecruiters: Talent acquisition platform focused on scheduling workflow, allowing interviewers and candidates to coordinate assessments at a scheduled time and date.
- Ashby: Modern ATS with powerful analytics built specifically for high-growth tech teams.

- Workable: Popular platform covering job posting, sourcing, and complete pipeline management. Workable’s scheduling workflow enables interviewers to set up assessments and interviews at a specific date and scheduled time, automatically sending pre-templated links to candidates and interviewers through calendar invites. This automation streamlines the process, resulting in a faster and more engaging experience for everyone involved.
- LinkedIn Talent Hub: An ATS that features native LinkedIn sourcing integration for seamless candidate discovery.
- Jobvite: Comprehensive talent acquisition suite known for its strong candidate engagement tools.
- Gem: Recruiting platform that successfully combines ATS, CRM, advanced analytics, and scheduling features.

What to look for in a skills testing platform’s ecosystem
When you’re choosing a technical assessment platform, the ecosystem around it matters just as much as the assessment itself. The right integrations determine how easily your team can access data, collaborate with interviewers, and turn a candidate's results into actionable reporting—without adding extra manual work.
Focus on the following steps:
Understand the difference between native and API-based integrations
Native integrations connect systems out of the box, making it faster to implement and easier to maintain. API-based integrations offer more flexibility, but they require ongoing developer resources to build and support. If your team wants to move quickly with fewer technical dependencies, prioritize native integrations with your existing tools.
Evaluate how data sync works across systems
Look for platforms that support bidirectional data syncing, not just one-way pushes. This ensures that updates made in your ATS or other systems are reflected everywhere, keeping your data accurate. It also allows recruiters to fetch reports, feedback from interviewers, and a candidate’s results directly within their primary workflow, improving both reporting and efficiency.
Check how easily you can access reports and insights
A strong ecosystem should make it simple to fetch detailed reports without switching between tools. Centralized reporting ensures that all relevant data—scores, feedback, and evaluation notes—is easy to access and review in one place, helping teams make faster, more informed decisions.
Assess security, SSO, and identity management
Secure access is critical, especially for larger teams. Integrations with SSO providers ensure that recruiters and interviewers can access the platform seamlessly while maintaining enterprise-level security. This becomes especially important as your hiring process scales.
In the end, the best platform isn’t just about the assessment experience—it’s about how well its integrations support your team’s workflows, data accuracy, and reporting from start to finish.
