Git

Git is the world's most widely used version control system — the foundation of collaborative software development. Every professional developer uses Git daily, and fluency in Git's branching model, workflows, and collaboration features is a baseline expectation for any engineering role.

What is Git?

Git provides distributed version control with a powerful branching model, comprehensive history tracking, and merge/rebase workflows. Core knowledge includes commits, branches, merging, rebasing, cherry-picking, stashing, reset/revert, remote repositories, pull request workflows, SSH authentication, .gitignore management, and resolving merge conflicts. Advanced usage includes Git hooks, submodules, git bisect for debugging, and tag management for releases.

Why Git matters for your career

Git is the universal infrastructure of software creation. Teams that use Git effectively ship code confidently, collaborate without conflicts, maintain clean histories, and recover from mistakes instantly. Developers who understand Git beyond the basics — rebasing, bisect, reflog — dramatically reduce time lost to version control issues.

Career paths using Git

Git proficiency is a baseline expectation for every Software Engineer, Data Engineer, DevOps Engineer, and Data Scientist working on code. Advanced Git skills are particularly valued in open source maintainers, platform engineers, and release engineering roles.

Frequently asked questions

Git merge vs. rebase — which should I use?▼

Use merge for preserving the complete history of feature branches (creates a merge commit). Use rebase for cleaning up local commits before pushing or for keeping a linear history on long-lived branches. The rule: never rebase commits that have been shared with others.

What's the difference between git reset and git revert?▼

git reset moves the branch pointer backward and can modify the working directory (risky for shared branches). git revert creates a new commit that undoes changes from a previous commit without rewriting history — the safe choice for shared branches.
