How would you run a mentoring-focused code review?

This question evaluates mentoring-focused code review competencies, including code quality and maintainability analysis, frontend architecture (React/TypeScript), testing strategy, accessibility and security awareness, plus written and interpersonal feedback skills.

Scenario

You’re given a poorly written frontend code change (e.g., a React/TypeScript component + related state and API calls) authored by a junior engineer. The code “works” but is hard to maintain.

Task

Conduct a code review and explain:

  1. What issues you would point out, prioritized by impact (correctness, security, performance, accessibility, maintainability).
  2. How you would communicate feedback so the junior engineer learns (tone, framing, asking questions vs. prescribing).
  3. What concrete refactors you would suggest (component structure, state management, separation of concerns, naming, typing, error handling).
  4. What tests you would add or request (unit, integration, UI/e2e) and what behaviors they should cover.
  5. How you’d follow up after the review (pairing, docs, conventions, future prevention).

Assume you can ask clarifying questions about requirements and constraints.
