In this blog post, we’ll explore the top 20 GitHub interview questions tailored for automation testers. These questions cover essential GitHub concepts, collaboration workflows, and version control practices, ensuring that candidates are well-prepared for their interviews.
What is Git, and how does it differ from GitHub?
Understanding the fundamental distinction between Git and GitHub sets the stage for comprehending version control and collaborative development.
Explain the purpose of a README file in a GitHub repository.
The README file serves as a guide to your project, providing essential information for users and contributors.
How do you clone a GitHub repository to your local machine?
Cloning is the process of creating a local copy of a repository. Walk through the steps and commands involved in this fundamental operation.
What is the significance of the .gitignore file?
The .gitignore file specifies which files and directories should be excluded from version control, preventing them from being tracked by Git.
Describe the Fork and Pull Request workflow on GitHub.
This collaborative workflow involves creating a personal copy (fork) of a repository, making changes, and then proposing those changes back to the original repository via a pull request.
How do you resolve a merge conflict in Git?
Merge conflicts occur when Git is unable to automatically reconcile changes. Understand the steps to manually resolve conflicts for a smooth collaboration.
Explain the difference between Git fetch and Git pull.
Git fetch retrieves changes from a remote repository, while Git pull fetches changes and merges them into the current branch. Understand when to use each command.

What are Git hooks, and how can they be useful?
Git hooks are scripts that run automatically at key points in the Git workflow, enabling automation and customization of various processes.
How do you revert a commit in Git?
Reverting a commit undoes changes without altering commit history. Understand the Git revert command and its applications.
What is Git rebasing, and when would you use it?
Git rebasing allows you to rewrite commit history, often used to maintain a clean and linear project history.
Explain the concept of Git submodules.
Git submodules allow the inclusion of one Git repository within another, facilitating modular and reusable code.
How can you view the commit history of a Git repository?
Use Git log to view the commit history, with options for filtering and formatting the output.
What is the purpose of Git tags, and how are they created?
Git tags are references to specific points in Git history. Learn how to create and manage tags for versioning.
Describe the differences between Git and GitHub branching models.
Explore branching strategies, such as GitFlow, GitHub Flow, and others, and understand their implications on collaboration and release management.
How can you contribute to an open-source project on GitHub?
Familiarize yourself with the process of forking a repository, creating a branch, making changes, and submitting a pull request to contribute to open-source projects.
