Universal coding tests

At TestGorilla, we use skills-based coding tests to evaluate candidates' expertise. Our library includes 12 tests, each designed to assess key programming principles such as algorithmic thinking, debugging, and data structures.

As a hiring manager, you can create challenges in up to 20 programming languages, allowing candidates to demonstrate their logic and problem-solving skills without restrictions.

Tests are auto-scored, with results ranked using percentile-based benchmarks. Scores are further detailed in a comprehensive coding test report, breaking down performance by correctness and performance. The report provides insights into how candidates tackled the questions and arrived at their solutions.

Universal coding tests prioritize problem-solving and adaptability over specific programming language expertise. By focusing on universal principles like logic and data structures, these tests assess transferable skills and encourage innovative solutions.

This approach broadens your talent pool, reducing biases tied to educational or socio-economic backgrounds, and welcomes candidates with diverse experiences and skills. It also fosters team diversity, creating a more flexible, resilient, and innovative workforce.

Allowing candidates to code in their preferred language improves the candidate experience, reducing anxiety and showcasing their true potential. This enhances your employer brand, attracting top talent to your organization.

TestGorilla offers one of the most comprehensive coding test libraries, featuring 400+ scientifically validated tests. These include universal coding tests covering 20 programming languages, such as JavaScript, Python, and Java, as well as frameworks like Node.js and Gatsby.js.

In addition to coding tests, TestGorilla provides a wide range of assessments for cognitive ability, personality and culture, and role-specific skills. Combining these tests in a multi-measure assessment delivers a complete picture of candidates' skills and capabilities.

Language-agnostic tests are also available, focusing on core programming concepts and allowing candidates to code in their preferred language. With tests available in 12 languages, it’s easy to expand the talent pool globally.

The platform simplifies candidate comparison through detailed assessment reports that include overall and test-specific scores, custom question responses, and annotation features for team collaboration. Customization options, including essay-style, multiple-choice, and video response questions, enable assessments to be tailored to specific hiring needs.

Yes, TestGorilla integrates seamlessly with all leading applicant tracking systems (ATS), ensuring that assessments, scores, and candidate insights automatically sync with your existing tools. This integration allows hiring teams to manage everything from their ATS, streamlining workflows and centralizing key information.

For additional flexibility, connectors like Zapier are also available, enabling further customization. TestGorilla’s integrations simplify the hiring process by letting you effortlessly send assessment invites, track candidate progress, and review assessment results—all directly within your ATS.

TestGorilla employs multiple layers of security and anti-cheating measures to ensure the integrity of coding assessments and give you full confidence in the results. These include:

1. Webcam Monitoring: Regular webcam screenshots (with applicant consent) provide a visual record of test sessions.

2. IP Address Monitoring: Verifies that the intended applicant is completing the test.

3. Dynamic Question Pools: Each coding test is supported by a database of possible questions, and candidates are presented with only one question, selected dynamically. Questions are rotated and replaced after reaching a maximum exposure threshold to reduce the risk of leaks.

4. Timeline Playback: View the candidate’s coding process from start to finish, including any copy-pasted elements (highlighted in yellow) for additional insight into their approach.

5. Code Validation and Test Cases: Review detailed validation results, including whether the candidate’s solution passed or failed specific test cases.

6. Functionality Restrictions: Copy-paste is disabled, and full-screen detection prevents candidates from searching for answers online during the test.

7. Time Limits: Strict time controls ensure assessments are completed promptly, minimizing opportunities for external assistance.
