💬 Potential Interview Questions

How does Next.js improve performance for fullstack applications?
Next.js enables server-side rendering, static site generation, and API routes, which collectively improve page load speed, SEO, and overall performance.
What are the key differences between REST and GraphQL APIs, and when would you use each?
REST uses fixed endpoints for resources, while GraphQL allows clients to request exactly the data they need. Use GraphQL for complex, dynamic data fetching and REST for simpler, resource-based access.
How do you structure a scalable Node.js backend using PostgreSQL?
Use a modular architecture with a clear separation of concerns, database pooling for performance, query builders or ORMs, and proper indexing for optimized queries.
What is your approach to implementing CI/CD pipelines for fullstack applications?
Automate builds, tests, and deployments using tools like GitLab CI or CircleCI, integrate code quality checks, and use environment-based deployments with rollback support.
How do you ensure high availability and reliability in production systems?
Use container orchestration (e.g., Docker + AWS ECS/EKS), monitor system health with Datadog, apply load balancing, and implement redundancy and failover mechanisms.
What monitoring strategies do you apply using Datadog?
Set up real-time metrics, alerts for errors and performance degradation, distributed tracing for APIs, and dashboard visualizations to track service health.
How do you handle authentication and authorization in fullstack apps?
Use JWT or session-based authentication, middleware for route protection, and role-based access control to manage user permissions securely.
What are the benefits of using Docker in development and deployment workflows?
Docker ensures environment consistency, simplifies dependency management, and enables scalable deployment using containers.
How do you optimize frontend performance in a Next.js app?
Use image optimization, code splitting, lazy loading, caching headers, and static generation to reduce load times and improve UX.
Describe your approach to mentoring junior developers on your team.
Offer code reviews with constructive feedback, pair programming, share best practices, and create learning opportunities through documentation and regular knowledge-sharing sessions.
