Question 1

In a Git workflow, what is the role of a 'code owner' file (e.g., CODEOWNERS)?

Accepted Answer

It automatically assigns reviewers based on file paths when a pull request is opened

Answer

A CODEOWNERS file maps file patterns to responsible team members, causing the platform to auto-request reviews from those owners when the relevant files change in a PR.

Question 2

What is semantic versioning (SemVer) and which format does it follow?

Accepted Answer

A three-part versioning scheme; format MAJOR.MINOR.PATCH

Answer

SemVer uses MAJOR.MINOR.PATCH where MAJOR increments on breaking changes, MINOR on backwards-compatible features, and PATCH on backwards-compatible bug fixes.

Question 3

Which Git feature allows developers to save uncommitted changes temporarily without creating a commit?

Accepted Answer

git stash

Answer

git stash temporarily shelves uncommitted changes in a stack, allowing the developer to switch context and later restore those changes with git stash pop.

Question 4

What is a 'fork' in the context of Git collaboration platforms like GitHub?

Accepted Answer

A copy of a repository in your own account, used to propose changes via pull requests

Answer

Forking creates a personal copy of another user's repository, enabling you to freely experiment and submit contributions back via pull requests without write access to the original.

Question 5

What does 'git bisect' help a developer accomplish?

Accepted Answer

Identify the specific commit that introduced a bug using binary search

Answer

git bisect performs a binary search through commit history, marking commits as good or bad until it pinpoints the exact commit that introduced a regression.
