Possible Interview Questions

Describe your experience building and deploying a .NET backend service end-to-end. What technologies did you use?

I built a microservice for a hotel booking system using .NET 6, PostgreSQL, and Docker. I designed the database schema, implemented business logic, and exposed RESTful APIs. The service was deployed on AWS ECS with CI/CD pipelines and monitoring.

How do you ensure your code is maintainable and scalable?

I follow SOLID principles, write unit and integration tests, and use code reviews. For scalability, I implement caching, optimize queries, and use async patterns. I also document architecture decisions.

Can you explain a time you had to troubleshoot a production issue? What steps did you take?

Once, a service had high latency due to a missing index. I used logging and APM tools to identify the bottleneck, then added an index and optimized the query. I also set up alerts to prevent recurrence.

How do you approach breaking down a complex feature into manageable tasks?

I start by understanding requirements, then identify dependencies and risks. I break the feature into smaller, incremental deliverables, each with its own tests. I estimate effort and prioritize based on business value.

What is your experience with AI-assisted coding tools, and how have they improved your productivity?

I use GitHub Copilot for boilerplate code and suggestions, which speeds up development. It helps with writing unit tests and exploring unfamiliar APIs. I always review the generated code for correctness.
