Technical Skills

1. Can you explain the difference between PUT and POST methods in HTTP?

Understanding the nuances of HTTP methods is crucial for web development and API design.

How to Answer

Discuss the primary differences in usage, such as idempotency and how each method affects server state.

Example

"PUT is used to update a resource at a specific URI and is idempotent, meaning multiple identical requests will have the same effect as a single request. In contrast, POST is used to create a new resource and is not idempotent, as multiple requests can create multiple resources."

2. Describe your experience with Infrastructure as Code (IaC) tools like Terraform.

This question assesses your familiarity with modern cloud infrastructure management.

How to Answer

Highlight specific projects where you implemented IaC, the challenges faced, and the benefits realized.

Example
