What re the differences between recruiters and sourcers at a company?

In typical companies, sourcers are responsible for the upfront outreach of new, passive candidates. Sourcers leverage a variety of tools including LinkedIn, blogs, GitHub, etc. to find potential candidates and then try to contact them directly. It is the sourcers responsibility to identify as many viable candidates as possible for a role. A recruiter is responsible for managing the entire recruiting process once a candidate is identified. Recruiters will help schedule interviews, help the candidate prepare for interviews, and ultimately manage the offer process for the candidate. Recruiters are also responsible for managing the relationship with the hiring manager for a role. They are the point of contact for the entire recruiting process and are responsible for ultimately filling the role.
