Git Interview Questions and Answers


Clearing a Git interview can appear to be a daunting task to anyone. However, by preparing several Git interview questions, you can drastically improve your chances of clearing the interview. If you are about to face a Git interview, there is a high possibility that you will get these Git related interview questions there.


Git has emerged as one of the most crucial parts of an organization in the modern market settings, creating ample job opportunities for every candidate. But a readily-available supply of applicants means a challenging hiring process. With the level of Git interview questions enhancing, every candidate must be thoroughly prepared.

That is why you need to go through these Git interview questions and answers to nail your interview. 

Overview Of Git Interview Questions

The interview questions for Git have been divided into three sections to make it easy for you to comprehend their nature. These three sections are domain-based, skill-based and scenario-based questions. 

Domain-Based Git Interview Questions

These domain-based Git related interview questions assess your knowledge of the concept. Therefore, you must prepare these Git interview questions regardless of your work experience.

Q 1. What is Git, and why is it used? 

Git is an SCMS (Source Code Management System) and DVCS (Distributed Version Control System) to monitor modifications made to a document. It also allows you to revert the specific changes to their original form. Furthermore, Git is beneficial when it comes to handling projects requiring speed and efficiency.

As a distributed infrastructure, Git offers numerous advantages over other control systems. As Git does not need to bank on a central server for storing every version of the document, it has the majority of the VCSs beat.

In Git's case, every developer can clone the repository with access to the project's entire history. In case of a server outage, you can quickly recover the local Git repository.

Using Git becomes a viable alternative since it offers numerous benefits such as:

- Git is suitable for any kind of business or industry

- Facilitating collaboration becomes simple with Git

- Git proposes esteemed network performance and disk utilisation

- It also proffers perks such as replication and high availability

Q 2. What is a VCS (Version Control System)? What are its different types?

To answer this or similar Git interview questions, you must provide an answer like:

You can define a VCS or version control system as a tool that creates different project versions. These versions are stored within a repository, and every change made to the code is tracked and monitored via the VCS.

The different types of VCSs are:

1. Local VCS: These version control systems possess a database maintaining every file modification in a particular format within the revision control.

2. Centralized VCS: These version control systems comprise a single repository, and every user can avail of their working copy.

3. Distributed VCS: These version control systems hold several repositories, and every one of them is available to different users as their copies.

Q 3. Mention the significant differences between SVN and Git.

In this case, the differences will be provided between SVN and Git:

- Git possesses a distributed VCS, while in the case of SVN, it is a centralised one.

- Access to networks is not compulsory for Git, while it is mandatory for SVN.

- Global revision number stays unavailable for Git, while the contrary is true in the case of SVN.

- When it comes to content, Git deals in Cryptographic SHA-1 Hash. On the other hand, SVN does not deal with any hashed content.

- SVN is preferred over Git for handling several projects within one repository.

- When it comes to commits across several branches, Git does not offer any. Contrarily, SVN allows users to create folders anywhere within the repository layout.

- No changes can be committed in Git, while SVN allows the users to develop a tag in a branch. It also facilitates several revisions under a single root tag.

Q 4. What are GIT stash drop and Git stash?

These Git interview questions need to be met with a clear definition. Here your answer should be:

Git Stash

Git stash takes the functional index & directory's concurring state and then pushes them towards the stack. This combination later returns to the user as an effectively functioning directory. You can use the Git stash in scenarios where you are indulging in a running project and intend to switch your work branch to something different.

Git Stash Drop

Git stash drop comes in handy after the user is finished with the job and intends to remove the stashed items from the list. The command Git "stash drop" will quickly eliminate the recently added stash items. It can also be used to eliminate particular items in case an argument is mentioned or included.

Q 5. State the difference between a clone, branch, and fork? 

When it comes to Git, the fork can be defined as the procedure of copying the repository. It is generally the experimentation within the project that does not affect the original copy. These are prepared to proffer modifications or to instil someone else's inspiration into the project.

Branches in the Git domain are referred to the individual projects in the Git repository. In the case of multiple branches within a repository, every branch can possess different folders and files.

Clones in the Git circle refer to preparing a copy or a clone of any pre-existing repository to an entirely new directory. Once cloning is performed, it establishes a connection that paves the way towards the original repository. This simplifies every interaction that happens with the primary repository.

Q 6. What is a Git directory?

When a repository is created, the user can find a Git directory already present there. The directory includes the repository's metadata while keeping up with every modification made to the repository via holding a commit history.

Every data regarding hooks, commits, object databases, refs, and repository addresses is stored within the said folder.

A Git directory acts as the most integral Git section. When the user clones any Git repository on the local machine, the said Git directory gets copied.

Ensure to conclude the answer for such Git interview questions by summarising everything in brief. 

Q 7. What language do you use in Git?

Git utilises the C language to amplify its speed by demising the runtime overheads associated with different higher languages.

Q 8. How can you deem Git better than Subversion?

As Git is an open-source VCS, it facilitates launching a project's versions, showing the code's modifications. It can also allow the users to trace backwards and undo the changes if the need arises. Using Git means several developers can quickly upload and check out modifications. You can also trace these changes back to specific developers.

Once you have prepared these Git interview questions and answers, you can move on to the next stage of skill-based Git related interview questions.

Skill-Based Git Interview Questions and Answers

If you apply for a higher position, the given Git related interview questions are a must for you. These questions and answers showcase your skills to the employer, making a vital difference.

Q 9. What do you do to fix a malfunctioning/broken commit?

To fix a broken commit, the user needs to input the command "git commit – amend." Once the command is launched, the broken commit can be fixed via the editor's message showing.

Q 10. How is a repository created within Git? 

As one of the most commonly asked Git related interview questions, you must answer this one with a lot of confidence.

If you intend to create a Git repository and the Git directory does not exist in the project, you must make it. You can achieve the same by inputting the "git init" command. Once you run this command, a Git directory will form within the project's directory.

Q 11. Explain the function of "git stash applies." 

The command "git stash apply" is used to get back to work where you had left. It brings back the changes that were saved on the current functional directory.

Q 12. How do you use Git instaweb?

You can use the "git instaweb" command to direct an internet browser and launch a web server via a functioning repository within the local repository.

Q 13. Mention some commonly used Git commands and elaborate on their purpose. 

- Git log: The command is used for enlisting the current branch's version history.

- Git rm [file]: You can use the command to delete files from the directory and stage the deletion.

- Git tag [commit]: The command is used to show the content and metadata modification within the specified commit.

- Git checkout [branch name]: You can use this command to switch to another branch.

- Git tag [commitID]: You can run the command to provide tags to a specific commit.

- Git checkout –b [branch name]": You can create an entirely new branch and switch to it via the command.

Q 14. What does a commit object comprise?

A commit object contains:

- Files that represent the project's state at a specific point

- References to every parent commit object

- The 40-character long unique string used to identify commit objects (SHAI name)

Q 15. How can a new feature be integrated within the primary branch?

If you intend to implement new functionalities within the primary branch, you have to use the "git pull command" or "git merge" command.

Scenario-Based Git Interview Questions and Answers

The interviewer will ask the given Git related interview questions to test your awareness and problem-solving capabilities. Every competent individual must be prepared to answer these scenario-based Git interview questions at a moment's notice.

Q 16. Imagine a conflict that arises in Git during an operating day. How will you fix it in the least time possible?

To resolve a conflict within Git, you need to:

- Assess the files giving rise to the conflict.

- Make every needed modification within the file to restrict the conflict from arising.

- Afterwards, the files need to be added via the "git add" command.

- In the end, you must run the "git commit" command to commit the modified document.

Q 17. Suppose you have already ousted and publicised a Git, how can it be reverted? 

If you are asked such Git interview questions, try to present the answer differently to showcase your grasp.

The two ways, in this case, will be:

- The first approach requires you to fix or remove the malfunctioning file within a new commit. Afterwards, you need to push it towards the remote repository's position. This method is the most viable one to resolve the error. After you have undertaken the required modifications, you must commit to the remote repository via the "git commit -m "commit message" command.

- The second approach to fix the issue will ask the user to create an entirely new commit undoing the malfunctioning commit's modifications. The same can be done via the "git revert <bad commit's name> command.

Q 18. What do you do to get the files' list modified within a specific commit? 

To get the list of every file modified within a specific commit, you need to use the "git diff-tree -r {commit hash} command.

The -r flag will allow the command to enlist individual documents.

The commit will list every file that was added or modified within the commit.  

Q 19. Suppose you need to explain the use and purpose of Git Bisect. How will you do it? 

The use of the Git Bisect command is to identify the specific commit introducing a bug via the binary search. The said command utilises binary search algorithms and locates the particular commit resulting in a bug.

The commit is shown "good" before the bug and "bad" afterwards. Afterwards, the command picks the commit between the endpoints to assess the commit's type. The procedures prolong until the faulty commit is changed. 

Q 20. If you were in a situation where you need to find out whether a branch is already merged into the master, how will you take action? 

Keep the answer for such Git interview questions direct.

To identify whether the branch is already merged, you can utilise the mentioned commands:

- Git branch –merged: The command will enlist every branch merged with the existing branch.

- Git branch –no-merged: The command will enlist every brand that has not integrated with the current branch.

Q 21. Imagine you are required to explain the difference between Git fetch and Git pull. How can you do so in simple terms?

The command Git pull is used to pull every new commit from a particular branch to the central repository. This updates the targeted branch within the local repository.

The command Git fetch serves a similar purpose as well, but its underlying feature differentiates a bit. Using the command pulls every commit from a particular branch within the central repository. However, it will keep the modifications within the local repository in a brand new branch.

Ensure your answer to such Git interview questions are brief and to the point.

Q 22. As a Git developer, what are the primary factors you find every user should be the most careful about?

This is a common interview question for Git, and your explanation should go like this:

To my understanding, software must be developed by comprehending the client's needs comprehensively. Another approach to software development understands the issues the software is aiming to resolve.

Our intent should be to make the software rich with user-friendly APIs and functionalities. Plus, it should possess highly-secure and reliable properties to gain the trust of the users. Additional factors like codes' length should also be a part of your answer to this Git interview question.

Q 23. How will you explain the Github development procedure to non-technical personnel?

The answer to these types of Git related interview questions should be straightforward like:

The Github development process is not much different from a standard software development process. It relies on the developer's knowledge of the factors involved and the software's requirements. It involves activities like:

- Analysing the requirements

- Explaining the project specifications

- Developing a functional software infrastructure 

- Integrating the features in real-time

- Testing the software for any issues

- Recording and reporting the errors

- Maintaining the software 

- Providing comprehensive support and training

Q 24. Have you ever used a gist in Git? What is it?

Yes, I have used a Gist in the Git development process. It can be used to share a developer's work like files, apps wholly or in proportion. Access to Gists is available to everyone, and since they are a Git repository, they can be cloned and forked.


With these Git interview questions and answers, your chances of cracking the interview will surge significantly. Prepare well and focus on keeping your answers crisp and confident and you will surely ace the interview!
