As one of the top source code management systems, Git plays a significant role in various businesses. Today, Git has over 70 million users all around the world.

The most widely used source code management technology is Git. Git's collaborative tools, such as bug tracking, task management, and wikis, will aid you whether you're a coder or a non-technical person.

This article will discuss the most common Git interview questions to help you crack an interview, , but before that let us first know about Git in detail.

Git Interview Questions

What Is Git and Why Is It Used?

Git is a distributed version control system used by software developers to manage the changes in the code. It also allows developers to collaborate and work together on their code.

Git works by creating repositories where the changes in the code can be stored. Thus it helps to keep track of the modifications and revert to the previous changes if required very efficiently.

Most asked Git Interview Questions in 2023

Let's discuss some of the most asked Git interview questions.

1. What exactly is git?

Answer: GIT is a distributed source code management and version control system. (SCM) solution designed to handle both small and big projects quickly and efficiently.

2. In Git, what language is used?

Answer:  Git is written in the C programming language. Git is fast, and the 'C' programming language enables this by reducing the overhead of high-level languages' run 

times. 

3. What is a repository?

Answer:  A repository comprises an a.git list that contains all of the catalog's metadata. Git keeps the contents of the .git file secret.

4. What are the steps to initialize a Git repository?

The steps below should be followed to create a Git repository:

Open the terminal window.

Navigate to the directory where the repository is to be created.

Run the command line:

git init

 

In the current directory, this will make a brand-new directory called.git. All of the repository's Git metadata may be found in this directory.

The repository with new files. The git add command can be used to include files in the repository. For instance, you would issue the following command to add the file README.md to the repository:

git add README.md

 

Add the modifications to the repository.

Use the git commit command to add the changes to the repository. For instance, you would issue the following command to commit the modifications to the file README.md:

git commit -m "Added README.md"

 

The commit message is specified by the -m parameter. A succinct summary of the changes you are submitting is provided in the commit message.

Push the updates to a distant repository.

5. What is the purpose of 'GIT PUSH'?

Answer:  'GIT PUSH' is a command that changes remote refs and associated items.

6. What does the word 'Version Control System' mean to you?

Answer: A version control system (VCS) keeps track of any changes made to a file or group of data, allowing you to go back to a specific version if necessary. This ensures that everyone in the team is working on the most recent version of the file.

7. Explain different types of version control systems?

Answer: VCSs are software solutions that assist in managing changes to source code and other files. Centralised and distributed version control systems are the two primary categories. 

Utilises a central server for code storage and version control (centralised, or CVCS).
Distributed (DVCS): Encourages decentralised collaboration by providing each developer with their own repository with a complete history.

8. Explain the difference between git fetch and git pull?

Answer: Git fetch retrieves changes from a remote repository without merging them. Git pull simultaneously collects updates and merges them into the active branch.

9. How does the use of GIT provide benefits?"

Answer: In software development, using Git has various advantages:

  • Multiple developers may simultaneously work on the same project. Git assists in conflict resolution and smooth integration of their updates.
     
  • Git's version control system keeps track of changes made to your code and lets you go back in time if necessary. It facilitates efficient code history management.
     
  • Creating branches in Git lets you work on modifications while the main codebase remains stable while you add new features or address bugs.
     
  • Git makes it possible for remote repositories to be hosted on websites like GitHub and GitLab, which makes it easier for scattered teams to collaborate.

10.What is the purpose of the git pull origin master?

Answer: The command git pull origin master gets all changes from the master branch and merges them into the local branch.

11. What is the purpose of the git clone command?

Answer: The git clone command copies a Git repository that already exists. Cloning is the most popular method used by programmers to obtain a copy of a central repository.

12. What is the purpose of 'git add'?

Answer:  'git add' adds updates to your index from your existing directory.

13. What is the purpose of the command 'git reset'?

Answer:  'Git Reset' restores your index and working directory to the state they were in before your previous commit.

14. What exactly are Git's 'hooks'?

Answer: This directory contains Shell scripts that are run after the related Git commands     are run.

15. What is the purpose of the command 'git log'?

Answer:  'git log' is used to discover individual commits in your project history by author, date, content, or history.

16. What is the purpose of the git clone?

Answer: One may use a Git clone to make a local copy of a remote GitHub repository. After you clone a repo, you may make changes locally on your PC rather than in the remote repo's source files.

17. What is GitHub?

Answer: A web-based platform called GitHub is used to host and collaborate on software development projects that use the Git version control system. It offers resources for hosting code, working together, tracking issues, and more. For a range of software development projects, from tiny personal endeavours to expansive open-source initiatives and enterprise-level systems, developers, teams, and organisations of all sizes use GitHub. It promotes collaboration, code sharing, and community-driven development and plays a key part in contemporary software development practises.

18. Explain the difference between Git and GitHub?

Answer: 

  • GitHub is a service, whereas Git is a tool.
     
  • While GitHub serves as the server for code repositories, Git is utilised to manage them.
     
  • GitHub offers a GUI, whereas Git is a command-line programme.
     
  • While GitHub is cloud-based, Git is either self-hosted or third-party.

19. What happens if you delete the .git directory?

Answer: If the .git/ directory gets deleted, you will lose track of your project's history.   Version control will be removed from the repository.

20. In Git, what command creates a Commit Message?

Answer: The command git commit -m "commit message" is used to send a message to a  git commit. A commit message is supplied using the flag m.

21. Give some examples of Git's fundamental operations.

Answer: The following are some fundamental Git operations:

  • Initialize
  • Add
  • Commit
  • Push
  • Pull

22. Give some examples of Git's advanced operations.

Answer: Some examples of Git’s advanced operations are:-

  • Git is-tree: It creates a tree object with the mode and names of all elements, as well as the blob or tree's SHA-1 value.
  • Git bisect: The Git bisect command aids in the identification of problematic commits.
  • Git rebase: Git rebase works in a similar way as git merge. With one exception, it merges two branches into a single branch. The command git rebase rewrites the commit history. 

23. What is the functionality of git ls-tree?

Answer: The contents of a tree object in a Git repository are listed by the git ls-tree command. References to files and other subdirectories inside a directory are contained in a tree object that represents that directory in the Git repository.

24. What is Git Bisect and how do you use it?

Answer: A tool called Git bisect can assist you in identifying the commit that caused a bug or regression in your code. It operates by progressively reducing the number of commits that could have potentially introduced the problem.

Determine a bad commit and a good commit before using git bisect. The bug-free commit is the good commit, whereas the bad commit is the one that caused the bug.

Once you have determined which commits were harmful and which were good, use the following command to begin bisecting:

"
git bisect start
"

25. What is meant by Git merge conflict?

Answer: When two commits to a Git repository modify the same lines of code, a Git merge conflict happens. Git encounters a merge conflict when it tries to reconcile the changes between the two commits automatically.

26. What is the functionality of git clean command?

Answer: Untracked files and directories are removed from a Git repository's working directory using the git clean command. Untracked files are those that are absent from the Git repository or index.

27. When should you use the git config command?

Answer: The git config command is used to configure your Git installation's configuration parameters. For example, after downloading Git, run the config instructions following to set up your login and commit email address in Git:

$ git config –global user.name “<username>”
 $ git config –global user.email “<email id>”

28. What exactly is SubGit?

Answer: SubGit is a tool that allows you to migrate from SVN to Git. TMate is the firm that created it. It transforms SVN repositories to Git, allowing you to work on both systems 

simultaneously. It automatically syncs SVN with Git.

29. How do you resolve a conflict in Git?

 Answer: If you need to resolve a conflict with Git, update the list to make the necessary changes, then execute "git add" to add the resolved directory, and then "Git commit" to commit the repaired merge.

30. Why is GIT superior to Subversion?

Answer: GIT is an open-source version control framework that allows you to execute 

'adaptations' of a job, which show the changes to the code over time and allows you to go back and repair those changes if necessary. Changes may be checked out and transferred by several developers, and each modification can subsequently, be ascribed to a specific developer.

31. Why is branching required in GIT?

Answer: You may retain your branch and hop between the different branches with the aid 

 of branching. You may access your previous work while leaving your current work intact.

32. Mention the numerous hosting options for Git repositories.

Answer: The Git repository hosting functions are as follows:

  • Visual Studio Online
  • Github
  • SourceForge.net
  • Bitbucket

33. What does the git status command do?

The git status command displays the current status of the working directory. It shows which files are in a modified, staged, or committed state.

34. Tell me something about git stash?

The git stash command is commonly used to save the changes made in the file temporarily without committing them to the repository such that the developer can work on other features by switching branches.

35. Can you give the differences between “pull request” and “branch”?

In Git, a pull request is a way to merge the changes made in the branch with the main code. In contrast, a branch is a copy of the main code that allows developers to work independently of the master branch.

Frequently Asked Questions

Q. Can we use Git without GitHub?

Yes, Git is usable independently of GitHub. Git is a distributed version control system, therefore the repository doesn't need to be kept on a single server. This means that even if you don't have internet access, you can still use Git to track your code changes.

Q. What are the scenario-based questions for Git?

Scenario-based questions related to Git may include questions like You are working on a branch, and you find a bug in the main code, and you have to fix it before other developers can continue their work. What should you do? 

Q. Which language is used in Git?

Git can be used with any programming language as it does not have any language-specific dependencies. The main languages of Git include C, C++, Java, Javascript, Typescript, PHP, Python, Ruby, Scala, etc.

Q. What is the main object of Git?

The main object of Git is to manage the source code. It makes the work of the developers more efficient and productive by helping them collaborate and work together. The main object of Git is the commit object, with the help of which a snapshot of the code is taken.

Q. What are the two basic jobs of Git?

Git offers many advantages to developers. Its two basic jobs are: it allows users to track the changes in the source code, and secondly, it allows developers to collaborate with each other.

Q. Which protocol is used by Git?

Git supports several protocols for smooth communication between local and remote repositories. Some important protocols used by Git are local, HTTP, Git, and secure shell.
