Preparing for any job interview has its challenges. This is especially evident in the software development world, where candidates are likely to be asked not only about their qualifications and interests but also about their knowledge of the tools they’ll be using in any given role. Take Git, for example. During a job interview where Git will be used, a candidate might be asked about her own experience using the free, open-source version control system (VCS) to store and manage a project's source code history as well as about Git itself, how it works, and why it’s the preferred VCS.
Fortunately, there are several common Git-based interview questions. These Git interview questions can be generic or specific, but they all share one thing in common: they require candidates to think carefully about how they will respond to interview questions on Git. Below are some of the more common Git interview questions and answers for experienced users.
Let us begin by looking at some of the Git interview questions at the beginner level.
Git Interview Questions and Answers for Beginners
1. What is the difference between Git and GitHub?
Prospective employers need to know whether you know the difference between Git and GitHub. Git is a tool that is used to manage all of your source code history, while GitHub is a web-based service that hosts Git code and other repositories.
2. What is the difference between Git and SVN?
Your understanding of SVN, a shortened term for the Apache Software Foundation’s Subversion, is just as important as your knowledge of Git. While Git is used for a range of project sizes, it is most suitable for smaller ones with fewer binary files. SVN, on the other hand, is ideal for handling multiple projects in the same repository, as well as frequently changing binary files.
3. What are some Git advantages over other tools?
A prospective employer may want to know why you prefer VCS. It also shows that you have compared it to other similar tools. During an interview covering Git interview questions and answers, you may want to say that it is a fast, free, readily available open-source technology that allows for collaboration and flexible workflow, helps avoid data redundancy and duplication, and enhances data integrity.

4. What is the programming language used in Git, and why do you think it’s used?
You will need to know several programming languages as a developer, but it’s essential to know which one Git uses if you will be working with it daily. Git uses the C programming language because the Git interface is quite fast, and C can keep up with it by reducing the number of overhead run times that can commonly occur with other programming languages.
5. What is a fork, a branch, and a clone in Git?
You will need to know these three terms to be able to work on any Git project. A fork is a copy of an existing repository on the server-side. A branch is something that manages changes within a repository. A clone is an identical local copy of a repository that includes all source code, branches, and history.
6. Why is branching necessary with Git?
You will need to think critically to show a prospective employer that you not only know the system but also understand why some key elements are used. Branching is essential because, as a developer, you can create your branches and jump among them without losing your previous work. You can also collaborate seamlessly with other developers within a project.

7. Why is the forking workflow preferred with open-source projects?
This question also forces you to think critically about why forking is an ideal workflow type. The forking workflow is more suitable for open-source projects because multiple developers can contribute to their server-side repositories.
8. Can you name a few Git repository-hosting services?
Answering this question shows a prospective employer whether you’re familiar with other systems outside of Git. Similar repository-hosting services include GitHub, GitLab, Bitbucket, Pikacode, SourceForge, and Visual Studio Online.
9. What do you envision for the future of Git?
This is a subjective question that you will need to prepare on your own. By thinking carefully about where you see Git advancing shortly, you can show a prospective employer that you’re looking ahead and visualizing Git’s future potential.
