Your engineers are reviewing
more code than ever before.Qualen lets you assess for it.
With Qualen, candidates review a PR, just like on the job. Then, our AI agent addresses PR comments in realtime, simulating a real engineer.

A complete review signal,
from invite to hiring decision.
Qualen turns code reviews into an assessment involving real engineering work to produce hiring-ready signals.
Candidates inspect real pull requests and leave comments on bugs, refactors, and security risks.
Set the level, specialization, language surface, and specialization constraints for each role.
See how efficiently candidates spend tokens, control cost, and turn PR feedback into revisions.
See how candidates reason, prioritize, and improve feedback over the session.
See how engineers handle code after the first read.
Candidates enter a small, realistic codebase with a pull request that is scoped enough to understand quickly.
Candidates read a realistic PR and comment on correctness bugs, refactors, and vulnerabilities.
Candidates submit their comments so Qualen can evaluate their priorities before generating a response.
Qualen addresses candidate comments and opens a fresh PR revision so reviewers can evaluate the next state.
The loop continues until time expires or candidates feel the code is ready to approve.
Calibrate every assessment to the role you're hiring for.
Difficulty
Match the bar to interns, new grads, mid-level engineers, or senior staff candidates.
Specialization
Focus the work on frontend, backend, infrastructure, security, or platform engineering.
Languages
Restrict to a few languages for depth or allow broad stacks for generalist hiring loops.
A scorecard your hiring team can actually discuss.
Every report connects candidate comments to code quality, risk detection, revision judgment, and practical hiring recommendations.
Assess the engineering work your team actually values.
Qualen gives candidates a real review loop and gives your team evidence that is easier to trust than another algorithm quiz.
