In most cases they still perform better than in-house HR/Recruiter departments. Their's job is to adverse job opening to as many candidates as possible and do initial filtering on location, salary and tech stack. For a jobseeker they are good because they often work with multiple companies to match you with a company or pass your resume to another requiter that have jobs with better fit. They can get you pass initial screen where clueless HR would reject yours resume because of spelling error. They often can provide information on hiring process based on experience with previous candidates. For a small company that cannot afford having a dedicated recruiter, they are an easy way to outsource responsibility of finding people. For a large non-tech company they are better than in house HR because they have basic understanding of the market.
