Git is the standard version control system used by every development team in 2026, essential at companies like GitHub, GitLab, Atlassian, and every tech organization. Whether you're preparing for a Software Developer, DevOps Engineer, or Full-Stack Developer role, these top 10 Git interview questions will help you prepare.

1. What is the difference between git merge and git rebase?

Merge creates a new commit combining two branches, preserving complete history. Rebase replays commits from one branch onto another, creating a linear history. Merge is safer for shared branches. Rebase produces cleaner history but should not be used on public branches.

2. Explain the Git workflow: working directory, staging area, and repository.

The working directory contains actual files. The staging area (index) holds changes marked for the next commit using git add. The repository stores committed snapshots permanently. Changes flow from working directory to staging to repository. git status shows the state of each area.

3. What is git cherry-pick and when do you use it?

Cherry-pick applies a specific commit from one branch to another without merging the entire branch. Use it for applying hotfixes to multiple branches, selectively moving features, or recovering specific changes. It creates a new commit with the same changes but a different hash.

4. How do you resolve merge conflicts in Git?

Conflicts occur when the same lines are modified in both branches. Git marks conflicting sections with conflict markers. Open the file, choose the correct changes, remove markers, stage the resolved file with git add, and complete with git commit. Use tools like VS Code or git mergetool.

5. Explain git stash and its use cases.

Git stash temporarily saves uncommitted changes without committing them. Use git stash to save, git stash pop to restore and remove, git stash apply to restore and keep. Useful when switching branches with uncommitted work, pulling updates, or temporarily shelving changes.

6. What is the difference between git reset and git revert?

Git reset moves the branch pointer backward, potentially removing commits from history. Git revert creates a new commit that undoes a previous commit's changes. Reset rewrites history and is for local changes. Revert is safe for shared branches as it preserves history.

7. Explain Git branching strategies.

Gitflow uses develop, feature, release, and hotfix branches. GitHub Flow uses main with feature branches and pull requests. Trunk-based development uses a single main branch with short-lived feature branches. Choose based on team size, release frequency, and project complexity.

8. What are Git hooks and how do you use them?

Git hooks are scripts that run automatically at specific Git events. Pre-commit hooks validate code before committing. Pre-push hooks run tests before pushing. Commit-msg hooks enforce commit message formats. Store in .git/hooks directory or use tools like Husky for team-wide hooks.

9. How does git bisect work?

Git bisect uses binary search to find the commit that introduced a bug. Start with git bisect start, mark a bad commit and a good commit. Git checks out the middle commit for testing. Mark each as good or bad until the problematic commit is found. Efficient for large histories.

10. What is the difference between git fetch and git pull?

Git fetch downloads new data from remote without integrating it into working files. Git pull is git fetch followed by git merge. Fetch is safer as it lets you review changes before merging. Pull is convenient but may cause unexpected merge conflicts. Use fetch for more control.
