Welcome to FreeCAD and the forum.
@work i am using now for nearly 14 years Solidworks.
Since most 3D CAD-Systems are similar in their basic workflow
I think learning something in general and learning a 3D CAD system
is always a good idea.
It might give you also a first "plus" in your Job-Applikation-interview,
showing you are willing to learn and you took initiative ...
