AI-Powered Coding Assessment Platform

What are Online Coding Tests?

Online coding tests are objective, performance-based assessments used to evaluate a candidate's technical proficiency, logic, and problem-solving skills. Unlike a resume, a coding test helps validate real-world ability to write, debug, and optimize code in a live environment.

Whether you are filtering through thousands of campus applications or headhunting for a niche senior role, Unstop’s coding assessments platform acts as a skills-first filter.

Frequently Asked Questions

Get to know us a bit more!

How do Unstop’s coding assessments combat cheating?

Unstop uses a multi-layered security approach, i.e., 360° AI proctoring with browser lockdown, device and tab switching, full-screen mode, and multiple-person detection; Aadhaar-based identity verification; and continuous environmental monitoring. We also offer a library of Scenario-Based problems that require architectural thinking, something AI cannot easily replicate.

Can I use the platform for both high-volume campus hiring and niche lateral roles?

Yes. Unstop’s online coding test platform is built for scale. For campus drives, you can automate the screening and assessments of 100,000+ candidates simultaneously with instant ranking. For lateral hiring, you can create high-complexity tests involving system design or specific tech stacks (like React, Go, or AWS) to ensure you are hiring seasoned experts, not just syntax-matchers.

How does the built-in code editor improve the candidate experience?

Our platform features a world-class Integrated Development Environment (IDE) that supports 75+ languages. It provides a familiar experience for developers with features such as autocomplete, syntax highlighting, and inline error notifications. By reducing "tool friction," we ensure candidates focus on logic, which leads to higher completion rates, seamless experience, and a better employer brand.

Can I transition top-performing candidates from coding tests directly into interviews?

Absolutely. This is the core of Unstop’s full-stack hiring automation ecosystem. Once the automated evaluation identifies your top scorers, you can move them into our Virtual Interview Platform with a single click. Our tool supports live coding Interviews where your team can collaborate with the candidate in real-time on the same code they just submitted.

How do coding tests help in reaching Diversity, Equity, and Inclusion (DEI) goals?

Coding tests are the ultimate skills-first filter. By using objective, automated scoring based on performance rather than a resume, you eliminate unconscious bias related to pedigree or background. Unstop also allows you to run blind assessments and targeted outreach to diverse talent communities (LGBTQ+, PwD, etc.), ensuring a meritocratic and inclusive pipeline.

Does Unstop integrate with my existing HRIS/ ATS systems?

Yes. Unstop has a smart built-in ATS that tracks candidate performance and compiles all the information in an intuitive dashboard for clear division making. All the information is structured and ready to be exported to your systems seamlessly.
