About this paper

Nima Yazdani, Aruj Mahajan, Ali Ansari

An LLM-driven recruitment support system, Zara, provides personalized and structured post-interview feedback to candidates and automates query resolution using OpenAI's GPT-4o. This system successfully resolved 75% of candidate inquiries and achieved a 4.37/5 NPS for AI interviews, alongside improved technical question quality and conversational dynamics.

Key insights

  • Large Language Models can be effectively deployed to provide scalable, personalized candidate support, addressing a long-standing challenge in recruitment feedback.
  • Implementing chain-of-thought and few-shot prompting with explicit guardrails enables LLMs to generate structured, constructive, and role-specific feedback while mitigating negative language.
  • Integrating RAG systems for query resolution substantially reduces the administrative burden on recruiters and ensures timely, consistent candidate communication.
