As a software developer preparing for Jenkins interviews, expect questions about automation processes. Jobs involving testing and automation often require knowledge of frameworks, automation tools, and core programming tools.
Jenkins is a popular open-source automation tool for software development. It helps automate testing, building, delivery, integration, and deployment.
In this article, we share the top 25+ Jenkins interview questions and answers that you must practice to ace your next technical round of interview. We share some interview questions for Jenkins for beginners, intermediate, and advanced levels.
In this section, we’ll look at some common beginner Jenkins interview questions and answers.
Continuous integration in Jenkins automatically integrates code changes. This ensures code is constantly updated, tested, deployed, and monitored.
This is a common Jenkins interview question asked at Java interviews. Continuous deployment is a core feature through which the integrated code is continuously deployed to the target environment, making the process flow smoothly without delay in processing.
This is another popular Jenkins interview question asked at technical interviews. Jenkins is primarily used for software automation and helps to perform the following functions –
The different types of Jenkins pipelines include – the Scripted Pipeline and the Declarative Pipeline. Scripted pipelines help developers custom-define various aspects of the job, while declarative pipelines use predefined commands.
To securely store credentials, you need to install the credentials plugin. The plugin stores a wide range of credentials, including Jenkins build tokens, usernames, passwords, AWS credentials, and vault-related credentials.

Jenkins is an open-source automation server that helps streamline software development processes. It’s crucial for implementing continuous integration and continuous delivery (CI/CD) pipelines.
Jenkins automatically builds and tests code changes as they’re committed, allowing teams to identify and fix integration issues quickly. This ensures a constantly updated and functional codebase.
Jenkins pipelines are a suite of plugins that support implementing and integrating continuous delivery pipelines. They provide an extensible set of tools for modeling simple-to-complex delivery pipelines as code.
While Jenkins is written in Java, it supports projects in many languages including Python, Ruby, and C++. Its plugin architecture allows for integration with various language-specific tools and frameworks.
Free-style projects are traditional Jenkins jobs configured through the web UI. Pipeline projects use scripts to define entire build/test/deploy pipelines, offering more flexibility and version control.
