Q: How do I approach Software Engineering Fundamentals interview questions?

Software Engineering Fundamentals questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master software engineering fundamentals interviews.

Question

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:

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

Assume you can ask clarifying questions about requirements and constraints.
