Recruiters and hiring managers should be involved in the screening process, and definitely make the final hiring decision. Where a third-party can help is in doing the things that are common across employers - a layer of screening that covers many of the soft skills and hard skills specific to that job type, but not specific to the company. Most employers don't do that very well. A third-party benefits from its expertise and focus - intellectual economies of scale, if you will. It can also make the experience much better for candidates. The status quo experience for job-seekers is terrible.
