Adding multiple hiring managers and have questions on the process

Content

I am adding 8 new hiring managers for our 8 restaurants and I am unsure of limiting their access to their particular store.  I have only been working with one store and I set her access up so she can only view her restaurant's applicants, but now that I have several more to add, I'm unsure if I follow the same process that all hiring managers will see all 9 locations.  I'm confusing myself and a little lost.
