Wallet Transfer Assignment Repository

This repository is a reusable coding assignment template for evaluating backend engineers on wallet transfers, idempotency, concurrency control, and double-entry ledger design.

Included

• ASSIGNMENT.md - candidate-facing prompt
• .github/pull_request_template.md - required PR structure
• .github/workflows/ci.yml - lint, format, test placeholder workflow
• .github/workflows/sonarqube.yml - SonarQube pull request analysis
• .github/copilot-instructions.md - repository-level Copilot review guidance
• evaluation_guide.md - reviewer rubric
• branch-protection-checklist.md - GitHub setup checklist

Intended use

1. Mark this repository as a GitHub template repository.
2. Create one private repository per candidate from the template.
3. Add the candidate as a collaborator.
4. Ask them to submit via a pull request into main.
5. Enable required checks, SonarQube, and Copilot review in GitHub.

Notes

• Copilot automatic pull request review is configured in GitHub repository or organization settings, not purely through files in the repo.
• The copilot-instructions.md file included here provides repository-specific review guidance once Copilot review is enabled.
• The CI workflow is language-agnostic by default and expects you to set the LINT_CMD, FORMAT_CHECK_CMD, and TEST_CMD repository variables or replace the commands directly.
