Building LinkedIn's Hiring Assistant: an agentic AI for recruiter sourcing, evaluation, and engagement at global scale

Candidate sourcing and evaluation are the most resource-intensive parts of recruiting, combining high-value decision-making with large volumes of repetitive pattern-recognition tasks that require human micromanagement to keep pipelines updated.

Outcome

Hiring Assistant reached global availability, enabling sourcing across 1.2+ billion profiles with enterprise-grade throughput and evaluating candidates in seconds via custom fine-tuned LLMs, freeing recruiters to focus on high-value work.

What failed first

A simple ReAct-style architecture was found insufficient for enterprise-grade recruiting: LLMs did not follow instructions reliably, produced hallucinations, and complex reasoning introduced unacceptable latency.
