### Sample Interview Questions

Describe your experience building public-facing APIs in Python. What frameworks and best practices do you follow?I have built several RESTful APIs using Flask and FastAPI, focusing on clean design, proper error handling, and thorough documentation. I follow best practices like versioning, rate limiting, and input validation. I ensure APIs are idempotent and stateless where possible.How do you approach scalability and performance optimization in a web service backend?I start by identifying bottlenecks through profiling and monitoring. I use caching (e.g., Redis), database indexing, and query optimization. For high-traffic endpoints, I implement asynchronous processing with message queues and horizontal scaling behind load balancers.Can you explain your experience with databases? Provide an example of how you designed a data model for a complex application.I have worked with PostgreSQL and MongoDB. In a recent project, I designed a data model for an e-commerce platform, using relational tables for orders and inventory, and a NoSQL store for user sessions to achieve low latency. I normalized data to reduce redundancy while ensuring query performance with appropriate indexes.Describe a time you automated testing in a project. How did it improve velocity and reliability?I introduced continuous integration with automated unit and integration tests using pytest. I also implemented end-to-end tests for critical user flows. This reduced regression bugs by 40% and sped up deployments because the team gained confidence in merging changes quickly.How do you handle working in a globally distributed remote team? What communication strategies do you use?I use asynchronous communication (Slack, email) for updates and sync video calls for complex discussions. I maintain clear documentation and status tracking in tools like Jira. Regular stand-ups and structured feedback help align across time zones.
