💬 Potential Interview Questions

What are the advantages of using Next.js for server-side rendering in a fullstack app?
Next.js provides built-in SSR for improved SEO and performance, simplifies routing, and integrates well with APIs and static site generation.
How do you structure a fullstack TypeScript project using Next.js and Nest.js?
Organize by feature modules, separate concerns between frontend and backend, use shared interfaces/types, and enforce code consistency via linters and tsconfig.
What’s your approach to managing authentication in a Next.js application?
Use middleware or API routes with JWT or session-based tokens, integrate providers like Auth0 or Firebase, and protect both client-side and server-side routes.
How do you handle data fetching and caching in React with GraphQL?
Use Apollo Client or URQL, leverage built-in caching, define normalized cache keys, and manage local state with client directives or reactive variables.
What are the key differences between REST and GraphQL and when would you use each?
REST has fixed endpoints and over-fetching issues, while GraphQL allows flexible queries; use GraphQL when you need fine-grained control over data retrieval.
Describe your CI/CD pipeline for deploying a Next.js app to AWS.
Use GitHub Actions to run tests, linting, build and deploy artifacts to S3/CloudFront or Lambda via Serverless Framework, with environment config via secrets.
How do you ensure scalability and performance in a Node.js backend?
Optimize asynchronous operations, use clustering, monitor with tools like PM2 or Datadog, and offload heavy tasks to queues like Bull or AWS SQS.
What best practices do you follow for writing reusable React components in TypeScript?
Use generic types, prop validation, composition over inheritance, isolate logic with hooks, and maintain a consistent style guide.
How do you handle technical debt in a long-term project?
Prioritize debt in sprint planning, create clear refactoring tasks, add tests before changes, and advocate for continuous code quality reviews.
What strategies do you use to mentor junior developers in a remote team?
Provide code reviews with actionable feedback, pair program, share resources, hold regular check-ins, and encourage open communication and questions.
