How to Answer

Discuss the architectural styles, use cases, and advantages of each. Highlight your experience with RESTful APIs, as they are more commonly used in modern web applications.

Example

“REST APIs are stateless and use standard HTTP methods, making them lightweight and easy to use. In contrast, SOAP APIs are protocol-based and provide more security features, which can be beneficial for enterprise applications. I have primarily worked with REST APIs in my projects, focusing on building scalable and efficient web services.”

2. Describe your experience with full-stack development.

This question assesses your breadth of knowledge across the software stack.

How to Answer

Mention specific technologies you have used for both front-end and back-end development, and provide examples of projects where you implemented full-stack solutions.
