💬 Potential Interview Questions

How do you architect a microservices-based full-stack application using Vue.js and Node.js (NestJS)?
Design modular services with clear APIs, use NestJS for scalable backend structure, manage state with Vuex or Pinia, and communicate between services via REST or messaging.
What are best practices when building reusable components in Vue.js?
Use props and slots for flexibility, define clear component interfaces, apply composition API for logic reuse, and ensure proper separation of concerns.
How do you handle deployment and CI/CD for full-stack applications using AWS and Kubernetes?
Use pipelines (e.g., GitHub Actions, GitLab CI) to build, test, and push Docker images, then deploy to Kubernetes clusters with Helm or manifests, leveraging AWS services like EKS and S3.
What is your approach to troubleshooting and performance tuning in Node.js applications?
Use profiling tools (clinic.js, node --inspect), monitor logs and metrics, optimize hot paths, avoid blocking I/O, and tune database queries.
How do you manage asynchronous tasks and background processing in a Node.js microservice?
Use queues (e.g., Bull with Redis), implement retry logic, isolate worker services, and ensure observability of task outcomes.
How do you ensure your Vue.js application is scalable and maintainable in a large project?
Structure with modules, enforce coding standards, use a shared component library, lazy load routes/components, and maintain separation of state and UI logic.
How do you ensure secure communication between microservices and frontend?
Use HTTPS, secure tokens (JWT), CORS policies, input validation, and API gateway patterns with authentication/authorization layers.
What are some challenges in using Kubernetes with Node.js services and how do you solve them?
Challenges include pod restarts, config management, and health checks; solve with readiness/liveness probes, config maps/secrets, and auto-scaling setups.
What techniques do you use for testing Vue.js and NestJS components and services?
Use Jest for unit and integration tests, Vue Testing Library for component testing, and define mocks for APIs and database layers.
How do you collaborate across globally distributed teams on full-stack projects?
Maintain strong async communication, detailed documentation, regular syncs, clear task ownership, and use tools like Jira, Confluence, and Slack effectively.
