Best continuous integration interview questions

Continuous Integration (CI) is a software development practice that involves merging code changes into a central repository frequently, often multiple times a day. It aims to catch integration issues early on and ensure that the software is always in a releasable state. As CI becomes increasingly important in the software development industry, it’s crucial to be well-prepared for CI-related interviews. In this article, we will discuss some common continuous integration interview questions to help you land your dream job.
