3. How do you approach debugging in a Node.js application?

Debugging is a critical skill for any software engineer, especially in a backend-heavy role.

How to Answer

Discuss your methodology for identifying and resolving issues, including tools and techniques you use.

Example

“I typically start by replicating the issue and using console logs to trace the flow of data. I also utilize debugging tools like Node Inspector and Chrome DevTools to set breakpoints and inspect variables, which helps me pinpoint the source of the problem.”

4. What is your experience with Azure Kubernetes Service (AKS)?

Given the requirement for experience with AKS, candidates should be prepared to discuss their familiarity with this platform.

How to Answer

Explain your experience with deploying and managing applications in AKS, including any challenges you faced and how you overcame them.

Example

“I have deployed several microservices on AKS, where I configured the cluster for auto-scaling and managed service discovery. One challenge I faced was optimizing resource allocation, which I addressed by analyzing usage metrics and adjusting the pod configurations accordingly.”

5. Can you explain the concept of RESTful APIs and how you have implemented them?

RESTful APIs are fundamental for backend development, and interviewers will want to assess your understanding and experience.

How to Answer

Define RESTful APIs and discuss how you have designed and consumed them in your projects.

Example

“RESTful APIs are based on stateless communication and use standard HTTP methods. In my previous role, I designed a RESTful API for a customer management system, implementing CRUD operations and ensuring proper authentication and error handling.”

Problem-Solving and Design

1. Describe a challenging technical problem you faced and how you resolved it.

This question assesses your problem-solving skills and ability to handle pressure.

How to Answer

Choose a specific example that highlights your analytical skills and the steps you took to find a solution.

Example

“I encountered a performance issue in a data processing application where the response time was significantly delayed. I analyzed the database queries and identified that some were not optimized. By indexing the relevant fields and restructuring the queries, I improved the response time by over 50%.”

2. How do you ensure code quality and maintainability in your projects?

Code quality is essential for long-term project success, and interviewers will want to know your practices.

How to Answer

Discuss your approach to writing clean code, including testing, code reviews, and documentation.

4. How do you stay updated with the latest technologies and industry trends?

Continuous learning is vital in the tech industry, and interviewers want to see your commitment to professional growth.

How to Answer

Share the resources you use to keep your skills sharp and how you apply new knowledge to your work.

Example

“I regularly read tech blogs, participate in online courses, and attend local meetups. Recently, I completed a course on microservices architecture, which I applied to a project by refactoring a monolithic application into microservices, improving scalability and maintainability.”

5. What strategies do you use to manage your time and prioritize tasks in a project?

Time management is crucial for meeting deadlines and ensuring project success.
