Have you used continuous integration and delivery systems in your previous workplace?

Yes, in practice, continuous integration (CI) and continuous delivery (CD) systems are often used to automate the building, testing, and deployment of applications.

For example, at my previous job, I used Jenkins and GitLab CI to automatically run tests on each commit to the repository, as well as to automatically deploy the application to test and production servers after all checks passed successfully.

This helps to speed up the development process, improve code quality, and reduce the likelihood of errors during releases.
