Jenkins interview questions help understand Jenkins, which helps testers and developers create robust software used in continuous integration and scalable building applications. The lifecycle of software involves developers creating an entire module which then goes for sanity and testing checks. However, during the development cycle, the testers are typically free and vice versa in the test cycle when the developers are free.

Testers must detect problems at the earliest. Jenkins uses automation of the build, deploy, test and analyse processes while allowing testers and developers to use Java code and continuous integration where multiple codes are jointly submitted and changes integrated into the project.

Jenkins suite thus has a lot of advantages in software development leading to smoother tested processes in the shortest of times by using the several plugins available.  If such a plugin is not readily available, one can code a new plugin and share it on the community platform for further tweaking. Jenkins interview questions revolve around Jenkins being easy to configure, set up and install and helping with continuous delivery and continuous process integration. As it is open-source software, it scores with its several thousand plugins and works across platforms using Java for its coding.

List of interview questions

As with the interviewer, Jenkins interview questions normally start with basic questions about its advantages, installation, etc. Once through this set, the level of difficulty in answering Git interview questions, Maven interview questions and answers, Jenkins advanced interview questions etc., are increased to match the interviewee’s knowledge on Maven interview questions for experienced interview questions on Git and Jenkins, Jenkins, pipeline interview questions and more. Always answer the Jenkins interview questions and answers crisply and to the point. Here’s our list of Jenkins interview questions to help one prepare for the interview.

  • What is meant by a trigger? Explain polling of the repository when a new commit is discovered.
  • Explain uses of the directory of JENKINS_HOME.
  • What and when is the backup plugin used? 
  • What does one do if one has a broken project build?
  • When working on a pipeline, if the second job fails, after the first job was successful, what should one do?
  • How do you copy and move Jenkins to a new server from an older one?
  • Explain what is meant by the Git plugin.
  • What is meant by Maven, and what benefits accrue when Jenkins and Maven are integrated?
  • How are automated tests run on Jenkins? 
  • Explain Kubernetes and how to integrate it with Jenkins?
  • Explain with an example what is cloud computing and where does Jenkins fit in?


Jenkins was originally known as Hudson and renamed by Oracle as Jenkins when it took over its ownership. Jenkins is a tool for real-time testing and continuous integration of largely automated builds. It reports the smaller builds of a larger Java code chunk, resulting in automation of the system, which is extremely time-saving for testers and developers alike.

When preparing for Jenkins interview questions, it is critical to revise by writing down simple use cases, the use of plugins like Git, Amazon EC2, Azure, Kubernetes, the types of pipelines, dashboard view, SCM, and such topics, interview questions on Maven, Jenkins tool and Jenkins basic interview questions. One should also use free resources like 189 Programming Questions and Solutions to build an exhaustive question base. So all the best for Jenkins interview questions!
