Creating A New "User" When Hiring A New Employee?

Summary

How do I automatically create a new user when we hire someone?

Hi - 

I think I saw the option where a new user profile would be created when we hire someone new.  I thought it was an option to click on when I moved them through a "status"

Where would I find that?

Also....if this is possible.....what access are they assigned and are they automatically notified that they have been added as a new user?

Ideally they would not be notified when it's created....also...we would need to go into their user profile and change their email address to our company one.
