You'll face Git interview questions in software developer interview rounds. The following Git interview questions and answers will help you nail your upcoming interview.
Git is a DevOps tool for source code management. It is a free and open-source version control system used to handle small to very large projects efficiently. Git is used to track changes in the source code, enabling multiple developers to work together on non-linear development.
Your interviewer can ask you about the following commands individually, or you may have to draw comparisons between them. You must prepare this crucial Git interview question thoroughly. The following table enumerates some key commands and their functions:
Git Commands and Functions
git config: It configures the username and email address.
git add: This command adds one or more files to the staging area.
git add <file_name>: It specifically adds files one by one.
git init: This command initializes an empty Git repository.
git commit: It allows you to commit changes to the head but not to the remote repository.
git stash: It provides a clean working directory for other tasks while pushing the current working directory state and index to the stack for future use.
git stash drop: It deletes the stashed element (last-added stash item by default) from the directory. Can also delete a specific topic included as an argument.
git stash pop: It discards the specified stash (topmost stash by default) after applying it.
git pull: It pulls innovation or commits from a specific branch of your central repository. It also updates your object branch in your local repository.
git fetch: It pulls all new commits from the desired branch. It then saves it in a new branch in your local repository.
git merge: It reflects the git fetch changes in your target branch. You can use git merge and specify the name of the other branch to bring it into the target branch.
git branch - merged: This command records the branches merged into the present branch.
git reset --mixed: You can use it for undoing changes of the working directory and the git index.
git merge --abort: It stops the merge process and returns back to the state before the merging occurs.
git revert: It creates a new commit to undo the changes of the previous commit. This command adds a new history without modifying the existing one.
git reset: You can use this command for undoing the local changes done in the git repository. It operates on the git index, commit history, and the working directory.
git status: It shows the difference between the working directory and the index.
git clone: It generates a copy of a current Git repository.
git remote: It helps you create, view, and delete remotes associated with the local repository.
git branch –d [head]: It simply deletes a branch.
git branch -d <local_branch_name>: You can use this command to delete a branch locally.
git push origin --delete <remote_branch_name>: You can use this command to delete a branch remotely.
git reflog: It tracks every single change made in the repository references and maintains the branches/tags log history, and thus gets the name reflog (reference + log).
git annotate [<options>] <file> [<revision>]: It annotates each line with information from the commit which introduced that change. It can also optionally annotate from a given revision.
git cherry pick: It introduces certain commits from one branch into another branch within the repository.
git bisect: It performs a binary search and detects the commit that introduced a bug or regression in the project’s history.

Here are some advanced Git interview questions for senior developers to help you ace the challenging interview rounds.
You must consider the following reasons while answering this Git interview question:
This Git interview question tests your branching knowledge with Git. You must elaborate on how you have utilized branching in your past activity. You can consider the following points while answering such Git interview questions:
Feature branching: A component branch model stores a majority of the changes for a specific element within a branch. The branch is converged into master when the item is tested and approved by automation.
Task branching: This model allows each assignment to be actualized on its branch with the undertaking key included in the branch name.
Release branching: You can clone the create branch that has procured enough features for a discharge to frame a release branch and begin the following discharge cycle. You cannot add new features after this point. It is the bug fixes, documentation age, and other release-oriented assignments that go in this branch.
The tool that migrates SVN to Git is termed Subgit. It effectively detects the settings of your remote SVN repository and downloads SVN revisions. It then converts them to Git commits, thereby emerging as a stable solution for a company-wide migration from SVN to Git. The primary reasons for using Subgit are as follows:
This is one of the most frequently asked Git interview questions. There are several advantages of the forking workflow over other popular git workflows, and you can compare them. You can highlight the following points while answering such Git interview questions.
Given below are some of the advanced Git interview questions for your practice:
This completes the list of important Git interview questions that will help you assess your preparation and learn vital topics at the same time.
