Fairness in AI-Driven Recruitment: Challenges, Metrics, Methods, and Future Directions

Dena F. Mujtaba, Nihar R. Mahapatra

TL;DR

The paper tackles the challenge of algorithmic fairness in AI-based recruitment by providing a systematic review of biases across sourcing, screening, interviewing, and selection. It synthesizes fairness metrics, bias mitigation strategies, and auditing approaches, and discusses legal and ethical guidance. The work offers a staged, multi-faceted framework to diagnose, measure, and mitigate bias, and outlines future directions such as standards, large-model auditing, open access, and human-in-the-loop governance. The findings aim to help practitioners implement fair, transparent, and accountable AI-enabled hiring that improves organizational outcomes and public trust.

Abstract

The recruitment process significantly impacts an organization's performance, productivity, and culture. Traditionally, human resource experts and industrial-organizational psychologists have developed systematic hiring methods, including job advertising, candidate skill assessments, and structured interviews to ensure candidate-organization fit. Recently, recruitment practices have shifted dramatically toward artificial intelligence (AI)-based methods, driven by the need to efficiently manage large applicant pools. However, reliance on AI raises concerns about the amplification and propagation of human biases embedded within hiring algorithms, as empirically demonstrated by biases in candidate ranking systems and automated interview assessments. Consequently, algorithmic fairness has emerged as a critical consideration in AI-driven recruitment, aimed at rigorously addressing and mitigating these biases. This paper systematically reviews biases identified in AI-driven recruitment systems, categorizes fairness metrics and bias mitigation techniques, and highlights auditing approaches used in practice. We emphasize critical gaps and current limitations, proposing future directions to guide researchers and practitioners toward more equitable AI recruitment practices, promoting fair candidate treatment and enhancing organizational outcomes.
