GitHub / GitLab / Bitbucket

Also written as GitHub, GitLab, Bitbucket, Bitbucket Server

Websites that host Git code repositories for teams, adding pull or merge requests, code review, issue tracking and built-in pipelines. GitHub is the most widely used; GitLab and Bitbucket (Atlassian's, often paired with Jira) are common inside companies.

Think of it like

A shared office for code: the filing cabinet, the review desk and the noticeboard in one place.

Junior or senior?

Table stakes for any developer, so not a differentiator.

Senior sounds like

Has set up branch protection, review rules or pipelines for a team.

Ask them

“What rules did your team set up on GitHub or GitLab for reviewing and merging code?”
