It will depend on the company.
Firstly, you'll create a profile on roleshare.com.
We will then match you to other candidates and surface roles. Our goal is to make your application process super easy and smooth - no different than any other role. We're still working that through, but have good things coming!
As for interviewing together or separately that will depend on the company and hiring manager's preference.
See the Roleshare Guide in the Toolkit for interviewing guidance and templates.
