Concepts you should be able to explain
Be prepared to explain the difference between Git and GitHub, repositories and forks, branches and pull requests, issues and discussions, GitHub Actions, secrets, environments, releases and branch protection.
Scenario-based questions
Practice situations such as: How would you safely publish a local project? How do you contribute without write access? How do you prevent direct pushes to production? How do you recover after committing a secret? How would you design CI for a pull request? How would you deploy only an approved release?
Professional mindset
GitHub expertise is not memorizing buttons. It means designing a workflow that makes collaboration traceable, automation repeatable, access controlled and releases reproducible.
