What is Candidate Sourcing?
Candidate sourcing is the proactive identification and engagement of potential candidates who have not applied to your role. It covers Boolean search on professional networks, talent-pool re-engagement, referrals and outbound outreach, and it feeds the top of the hiring funnel alongside inbound applications.

Sourcing and inbound applications solve different problems. Sourcing reaches passive candidates who are not looking, which matters for scarce senior and specialist roles. Inbound flow dominates for high-volume and generalist roles, where the constraint is not finding people but evaluating the many who already applied.
Diagnose the actual bottleneck before investing. If you receive 300 applications per role and interview 12, sourcing more candidates will not help — the constraint is screening throughput, which is solved by interviewing every applicant rather than by adding more of them.

Talent Pool
A talent pool is a maintained database of candidates who are potential future fits — silver-medallists from prior searches, sourced prospects, referrals and past applicants who consented to be retained. It shortens future searches by starting them with warm, pre-qualified candidates.
Boolean Search
Boolean search is a query technique combining keywords with the operators AND, OR and NOT, plus quotation marks for exact phrases and parentheses for grouping. Recruiters use it to search résumé databases and professional networks with far more precision than plain keyword search.
Recruitment Marketing
Recruitment marketing applies marketing practice to talent attraction: employer brand, careers-site content, job-post copy, distribution channels and conversion measurement. Its objective is a larger and better-matched applicant pool for each open role.
Hiring Funnel
The hiring funnel describes the narrowing progression of candidates from awareness of a role through application, screening, interview, offer and acceptance. Measuring conversion between adjacent stages isolates exactly which step is losing candidates and why.
