💬 Potential Interview Questions
-
How do you ensure your Node.js backend services are scalable and resilient on AWS?
Use load balancing, stateless design, auto-scaling groups, retries with exponential backoff, and AWS services like Lambda, ECS, or EKS with proper monitoring and alerting. -
Explain your approach to building secure RESTful APIs.
Validate all input, use HTTPS, implement authentication (OAuth/JWT), authorization checks, rate limiting, and proper error handling to avoid exposing internal logic. -
What’s your experience with React and TypeScript in building complex UIs?
I build reusable components with strict typing, use hooks effectively, manage state with tools like Redux or Zustand, and write unit tests with Jest and React Testing Library. -
How do you handle CI/CD pipelines in projects with Bitbucket or CircleCI?
Configure pipelines to run tests, linting, build steps, and automated deployments, with environment-specific variables and approval gates for production deployments. -
Describe your strategy for managing technical debt alongside feature development.
Prioritize critical debt items during sprint planning, include refactoring in regular cycles, and advocate for scalable design early to reduce future rework. -
How do you ensure observability in full-stack applications?
Implement logging (structured and centralized), metrics (e.g., Prometheus), distributed tracing, and health checks across backend and frontend layers. -
Give an example of using serverless or Lambda-based architecture effectively.
Used AWS Lambda to handle asynchronous background tasks like file processing or webhook handling, with SQS for buffering and CloudWatch for monitoring. -
What’s your process for handling production incidents in distributed systems?
Monitor actively, analyze logs/traces, isolate affected components, roll back if necessary, communicate with stakeholders, and implement postmortem fixes and automation. -
How do you write testable code and ensure coverage in Node.js and React apps?
Follow SOLID principles, decouple logic, use dependency injection, write unit/integration tests with Jest, and monitor code coverage reports. -
How do you collaborate in cross-functional remote teams effectively?
Maintain clear async communication (Slack, docs), use daily standups and sprint ceremonies, document decisions, and promote transparency and mutual support.
