Possible Interview Questions

Describe a complex full-stack project you led. What were the challenges and how did you overcome them?

I led the migration of a monolithic application to a microservices architecture using Node.js and React. The main challenge was ensuring zero downtime. I implemented a gradual migration strategy with feature flags, used Docker for containerization, and set up CI/CD pipelines for automated deployments.

How do you ensure the performance and scalability of a Node.js application?

I focus on asynchronous programming, use caching with Redis, implement pagination for database queries, and leverage load balancing. I also use monitoring tools like New Relic and conduct load testing with Artillery.

Explain your experience with TypeScript in a React project.

In my last project, I refactored a large React codebase to TypeScript. This improved code maintainability and reduced runtime errors. I defined strict interfaces for props and state, used generics for reusable components, and configured ESLint with TypeScript rules.

How do you handle state management in React applications?

For global state, I use Redux Toolkit with Thunks for async actions. For server state, I prefer React Query which simplifies data fetching and caching. For local state, I use useState and useReducer. I choose based on the complexity and scale of the app.

Describe your experience with cloud services, specifically AWS.

I have extensive experience with AWS including EC2, S3, RDS, Lambda, and CloudFront. I set up a serverless backend using Lambda and API Gateway, managed databases on RDS, and implemented auto-scaling for EC2 instances. I also use CloudFormation for infrastructure as code.
