Understanding the distinctions between these two API styles is crucial for a software engineer, especially in a cloud-based environment.

How to Answer

Discuss the architectural principles behind REST and SOAP, highlighting their use cases, advantages, and disadvantages.

Example

"REST is an architectural style that uses standard HTTP methods and is stateless, making it lightweight and easy to use. In contrast, SOAP is a protocol that relies on XML and has built-in error handling and security features, making it more suitable for enterprise-level applications where security is a priority."

2. Describe your experience with CI/CD pipelines.

Continuous Integration and Continuous Deployment are essential for modern software development practices.

How to Answer

Share specific tools and practices you have used in CI/CD, emphasizing how they improved your development workflow.
