Use structured tasks to test and measure onboarding. Particularly for juniors this can be essential for learning and growth plans1. For example:
Create a toy repo, after the employee feels they have a strong feel for git, ask them to perform a series of common tasks that would encounter on a day-to-day basis:
- Staging work
- Making a well formed commit message
- Diff against a different branch
- Rebase a branch with conflicts
- Open a PR on the toy repo
