Real PR review tasks
Candidates review a realistic pull request and leave comments on correctness bugs, refactors, and vulnerabilities, giving hiring teams evidence from actual review behavior rather than quiz answers.
Merge
Merge is an AI-native 30-minute code review assessment for engineering hiring. Evaluate how candidates review PRs, handle revisions, and spot bugs, refactors, and security risks.
What Merge is
Merge is an AI-native code review assessment platform for engineering hiring. It asks candidates to review a pull request in a realistic codebase, leave comments on issues they notice, and respond to revisions as an AI agent updates the PR in real time.
The product is positioned for teams that want to evaluate how engineers actually review code rather than relying on generic algorithm quizzes. Merge frames the workflow as a review loop that surfaces how candidates reason about bugs, refactors, security risks, and feedback over time.
Core capabilities
AI-driven revision loop
The platform includes an AI agent that addresses candidate comments in real time and publishes a revised PR so reviewers can inspect how the candidate responds to changes.
Custom role calibration
Assessments can be adjusted by difficulty, specialization, and language surface so the exercise fits the role being hired for.
Token-use visibility
The site highlights token use and efficiency, showing how candidates spend tokens, the estimated cost of their interaction, and how they revise feedback over the session.
Hiring-focused reporting
Merge produces a scorecard that connects comments to code quality, risk detection, revision judgment, and hiring recommendations.
Practical use cases
Hiring engineers who review code
Screen candidates for engineering roles by observing how they inspect a pull request, identify bugs, and explain the reasoning behind their comments.
Role-level evaluation
Compare candidates at different seniority levels by adjusting assessment difficulty from intern or new graduate through staff or principal.
Specialized technical hiring
Focus the task on a specific discipline such as frontend, backend, infrastructure, security, platform, systems, APIs, or data pipelines.
Evaluating revision judgment
Review how applicants respond when code changes after their feedback, which can help teams assess judgment and adaptability during iterative review.
Pros and Cons
Pros
- Uses a realistic pull request workflow instead of an abstract quiz.
- Lets teams tune assessment difficulty, specialization, and language to the role.
- Shows how candidates handle feedback across repeated revisions, not just one static review.
- Includes reporting that links candidate comments to code quality and practical hiring recommendations.
- Surfaces token use and efficiency as part of the evaluation.
Cons
- The publicly available source is limited, so pricing, integrations, and implementation details are not confirmed here.
- The assessment appears focused on code review ability, so it may not cover broader engineering skills outside that workflow.
FAQ
How does Merge’s assessment workflow work?
Merge is designed to assess candidates by having them review a pull request and comment on issues such as bugs, refactors, and security risks. The site also says its AI agent responds to those comments in real time and opens a revised PR for the candidate to review next.
What does a candidate do during the assessment?
The homepage describes a complete review loop that includes reading a small realistic codebase, reviewing a PR, submitting comments, and then evaluating the next revision after Merge publishes one. The assessment continues until time expires or the candidate feels the code is ready to approve.
Can assessments be customized for different roles?
Merge says assessments can be calibrated by difficulty, specialization, and language. The site mentions roles ranging from intern and new graduate to senior, staff, and principal, and focuses on areas such as frontend, backend, infrastructure, security, platform, systems, APIs, and data pipelines.
What information is available about pricing and integrations?
The site presents Merge as a 30-minute online code review assessment, but it does not publish pricing, setup steps, or integration details on the homepage source provided.
