Git Certificate

# Git certificate - outline

## Part 1 - exam (45 min)

Topics:
- Working tree, index, HEAD
- Branching strategies (trunk-based, GitFlow, environment branches)
- Merge vs rebase vs cherry-pick
- Recovery: reflog, bisect, restoring lost work
- Collaboration: signed commits, CODEOWNERS, protected branches
- Submodules vs subtree vs monorepo

Passing mark: 70 percent.

## Part 2 - practical (take-home, ~3 hours)

Demonstrate the skills end-to-end:

Task A - Recovery:
- Given a repo with a recent bad force-push, recover the lost branch using reflog
- Document the recovery commands you used

Task B - Clean history:
- Take a messy 12-commit feature branch and rebase it into 3 logical commits
- Use --autosquash with --fixup commits

Task C - Bisect:
- Find the commit that introduced a regression in a small repo
- Document the bisect transcript

Task D - Collaboration:
- Fork a public repo, add CODEOWNERS, sign your commits, open a PR with a clean summary
- Wire pre-commit hooks (prettier, eslint) so the PR is green

Submit a Git repo + a markdown file documenting each step.

## Grading

- Recovery (25 percent)
- Clean history (25 percent)
- Bisect transcript (20 percent)
- Collaboration PR + signed commits (30 percent)

## Tips

- The certificate is calibration; the documented transcripts are what employers will read
- A clean rebase before a PR is the single best signal of seniority on a team
