Candidate Sourcing

Glossary of HR Terms Candidate Sourcing

What is Candidate Sourcing?

Candidate Sourcing is the proactive process of identifying, attracting, and engaging potential job candidates, both active job seekers and passive talent, before they apply to open positions. It involves using multiple channels such as job boards, social media, networking, and talent databases to build strong pipelines for current and future hiring needs.

Why it matters

Relying only on applicants who respond to job postings limits the talent pool. Candidate sourcing expands reach, improves quality-of-hire, and reduces time-to-fill by ensuring a steady stream of qualified prospects. Strong sourcing strategies also help companies compete in tight labor markets and fill specialized or hard-to-hire roles.

Where it fits in the HR stack

Candidate sourcing sits within the talent acquisition and recruiting layer of the HR stack. It is often powered by ATS (Applicant Tracking Systems), CRM (Candidate Relationship Management) tools, and sourcing platforms (e.g., LinkedIn Recruiter, Entelo, or SeekOut) that integrate with HRIS once a hire is made.

Common use cases/Examples

  • Building a pipeline of software engineers using LinkedIn Recruiter or GitHub.
  • Engaging passive candidates through personalized outreach campaigns.
  • Hosting university recruitment events to identify early talent.
  • Using AI-powered sourcing tools to match skills with open roles.
  • Maintaining a talent pool for future hiring needs.

Examples of companies that use it

  • Tech companies like Google and Microsoft, which invest heavily in sourcing top technical talent.
  • Enterprises such as Deloitte and PwC, which use large-scale sourcing strategies across universities and global markets.
  • SMBs and startups using platforms like Greenhouse Sourcing Automation, Hired, or Lever Nurture to find candidates in competitive niches.

FAQ

Recruiting covers the entire hiring process, while sourcing focuses specifically on finding and engaging candidates before they apply.

Yes. Sourcers identify and reach out to candidates, while recruiters manage interviews, candidate experience, and closing offers. In smaller companies, one person may do both.

Passive candidates are individuals not actively applying for jobs but who may be open to opportunities if approached with the right role.

Partially. AI-driven tools can scan databases, job boards, and social media to suggest matches, but human judgment is still key to personalization and relationship building.

Key metrics include source of hire, response rates, quality of candidates sourced, time-to-fill, and pipeline diversity.
