1. What is Git and how does it differ from other VCS?
Git is a distributed version control system where every developer has a complete copy of the repository. Unlike centralized systems like SVN, Git works offline, supports fast branching, and handles merging efficiently. It tracks changes using snapshots, not file differences.
2. What is the difference between git merge and git rebase?
Git merge creates a new merge commit combining two branches while preserving history. Git rebase moves commits to the tip of another branch creating a linear history. Use merge for shared branches and rebase for cleaning up local feature branches before merging.
3. Explain the Git branching strategy.
Popular strategies include Git Flow with develop, feature, release, and hotfix branches. GitHub Flow uses main branch with feature branches and pull requests. Trunk-based development uses short-lived branches merging frequently to main. Choose based on team size and release frequency.
4. What is a pull request and code review process?
A pull request is a proposal to merge changes from one branch to another. It enables code review where team members review code for quality, bugs, and standards. Reviews include inline comments, approvals, and requested changes. Use templates for consistent PR descriptions.
5. How do you resolve merge conflicts?
Merge conflicts occur when two branches modify the same file lines. Git marks conflicts with special markers. Resolve by editing the file to choose the correct changes, then stage and commit. Use git mergetool for visual conflict resolution. Prevention is better through communication.
6. What is git stash and when do you use it?
Git stash temporarily saves uncommitted changes without committing them. Use it when you need to switch branches but have work in progress. Commands include git stash save, git stash pop, git stash list, and git stash apply. Stash can include untracked files with -u flag.
7. Explain git cherry-pick and its use cases.
Git cherry-pick applies a specific commit from one branch to another. It copies the commit creating a new commit with the same changes. Use it for applying bug fixes across branches, selective feature porting, and recovering lost commits. Avoid overuse to maintain clean history.
8. What is git reset vs git revert?
Git reset moves the HEAD pointer and can unstage or discard commits. It rewrites history and should not be used on shared branches. Git revert creates a new commit that undoes a previous commit without rewriting history. Use revert for public branches and reset for local changes.
9. How do you write good commit messages?
Use imperative mood in the subject line. Keep the subject under 50 characters. Separate subject from body with a blank line. Explain what and why in the body, not how. Reference issue numbers. Use conventional commits format like feat:, fix:, docs: for automated changelogs.
10. What are GitHub Actions and CI/CD pipelines?
GitHub Actions automate workflows triggered by events like push, pull request, or schedule. Define workflows in YAML files. Common uses include running tests, building applications, deploying code, and checking code quality. They integrate with the entire GitHub ecosystem.
Conclusion: Git mastery is non-negotiable for every developer. Practice branching strategies, conflict resolution, and collaborative workflows to excel in your interviews.
