Qualified is a technical skills assessment platform — a web-based coding-test tool that lets you evaluate engineers on real, framework-backed coding challenges instead of algorithm trivia. If you already have a pipeline of candidates and need a fair, standardized way to measure how they actually write code, it's one of the more developer-respected options out there. Qualified was founded in 2016 by Nathan Doctor (CEO) and Jake Hoffner (CTO), the same team behind Codewars — the gamified coding community that has drawn millions of developers to sharpen their skills on real challenges. That lineage matters: Qualified grew out of a genuine developer culture, not a generic HR-tech playbook. In March 2023, Andela acquired Qualified to power the assessment and certification layer inside its global talent network. Andela has said it continues to offer Qualified as a standalone product, so you can still buy it as an assessment tool on its own. The acquisition also folded Codewars' 3.6M+ engineering users into Andela's community. Companies including Klarna, Zoom, and Apple have used Qualified to assess and train engineering talent at scale.

The core idea is simple and it's the right one: measure engineers on realistic work, not whiteboard puzzles. Qualified delivers coding assessments and custom projects through a browser-based IDE, then scores submissions automatically using real unit-testing frameworks — Mocha, RSpec, PHPUnit, JUnit and others — so the evaluation reflects the same tools engineers use on the job. It supports a broad stack: React, React Native, Angular, Vue, Node.js, Django, Flask, Ruby on Rails, Spring, .NET, plus databases like PostgreSQL, MongoDB and Redis, and even Solidity. You can run auto-scored take-homes or turn any assessment into a live pair-programming session to talk through a candidate's approach.

Qualified is an assessment layer, and it's a strong one — but it's a tool that measures the candidates you already have. It answers "can this person code well?" once someone is in front of you. The sourcing, the outreach, and the decision about who lands in the funnel in the first place are still your job. It's also a screen, not an employment relationship. A great score tells you a candidate is capable; it doesn't hire them, run payroll, or handle the contract and compliance that turn a passed test into a working engineer. And like every take-home platform in 2026, it lives in an arms race with AI-assisted candidates — the similarity detection helps, but a test still measures a moment, not sustained real-world delivery.

Here's the honest gap a test can't close: the best engineers usually aren't the ones sitting in your funnel waiting to take an assessment. The ones you actually want are already working — booked on a contract somewhere else, heads-down, not applying, not signing up for a coding challenge. Nextdev reaches the top 1% of AI engineers — the ones who aren't looking. We find them, then we give each a real problem to build and watch how they actually work. So you know they're AI-native because you've seen it, not because a profile said so and not because they cleared a take-home in one sitting. Then we do the part a test never will: we employ them for you. One named engineer, working on your problems. The contract, payroll, and compliance never touch your desk. A tool scores the people who showed up. We bring you the engineer who never would have.

Qualified is a genuinely good assessment platform — real testing frameworks, code playback, and developer credibility earned through Codewars, now backed by Andela. If you have candidates in hand and want to measure how they code on realistic work, it's one of the best tools for that job. Just be clear about what it is: a way to test the people already in your pipeline, not a way to find and employ the engineer you actually need.
