1. Must-Have skill.
Git is a tool that many companies will use in their daily development. So your Git skills can help you to get a job.
2. Opensource your personal profile
If you want to show your skills level to a recruiter or a hiring manager, your code maybe the best way for you to demonstrate your skills level. Having your project opensourced on Git would allow people to see your code and potentially improve your code quality
Thus far, these are all I can think of, but may add to this list later.
