The work problem
A recruiter's job mixes work that needs judgement with high-volume pattern recognition. Sourcing and assessing candidates are the most labour-intensive stages. LinkedIn faced a scale problem of finding and assessing candidates among more than 1.2 billion profiles.
Technology and data
Hiring Assistant creates a separate agent instance per recruiter and runs on asynchronous messages. At the centre sits a supervisor agent that interprets the request and distributes work to sub-agents. Plan-and-Execute was chosen over ReAct. A planner builds a structured plan and an executor uses tools in a ReAct fashion. The sub-agents are split into requirement definition, candidate sourcing, assessment, outreach, screening, learning and memory. The sourcing agent uses LinkedIn Recruiter Search and Recommended Matches and looks at talent supply and movement through the Economic Graph and Talent Insights. The assessment agent gathers profiles, résumés and past contact records and produces a recommendation with reasoning. A custom LLM dedicated to assessment was built, and speculative decoding was used to cut response time.
Results
LinkedIn did not disclose performance figures. Instead it said assessment starts only after the recruiter first reviews the qualification requirements and a Responsible AI policy check has been run. Whether to move a candidate to the next stage is the recruiter's decision. Changes to qualification requirements proposed by the learning agent are also applied only after recruiter review and approval. It said memory data stays inside that recruiter's environment and is not used for LLM training.
Limits and open questions
The source gives no figures for a shorter time to hire or a change in hiring quality. It is also not material that demonstrates results at a specific client company.
