You’d be surprised at the amount of people at Microsoft that their entire career have been at Microsoft (pre-git-creation) that never used Git. Git is relatively new (2005) but source control systems are not.
To have never touched it in the last decade? You've got a gap in your CV.
These are young industries. So most hiring teams expect that you take the time to learn new technologies as they become established.
Turn it around: If I were to apply for a job at Microsoft, they would probably find that my not using Windows for over twenty years is a gap on my CV (not one I would care to fill, mind).
