As answered by people managing GitHub Codespaces and Reviewly.
Reviewly's answer:
It delivers take-home coding assessments directly through GitHub, using real repositories, issues, and pull requests. The entire workflow—from project setup to anonymized code reviews—is automated. This creates a realistic developer experience while saving time and reducing bias in the evaluation process.
Reviewly's answer:
Most platforms rely on artificial coding environments or complex admin tools. This solution integrates seamlessly with GitHub, making the process natural for developers and simple for teams. It automates project distribution, reviewer assignment, and feedback collection, ensuring consistent, fair, and efficient technical evaluations.
Reviewly's answer:
The primary audience is engineering teams and hiring managers at tech companies who care about high-quality, fair developer assessments. They’re typically mid- to senior-level professionals looking to streamline technical hiring, reduce bias, and evaluate candidates based on real-world coding ability—not artificial tests.
Reviewly's answer:
It was built by software engineers that sit on both sides of the table who were frustrated with clunky, unrealistic coding assessments. They wanted a way to evaluate candidates using real tools—specifically GitHub—while automating the repetitive parts of the process. The goal: make hiring feel more like real engineering work, not a separate, rigid system.
