TLDR: A recent study by researchers from the University of Chicago and Erasmus University Rotterdam found that job applicants interviewed by AI agents were 12% more likely to receive job offers and 17% more likely to remain in their positions for at least the first month. The large-scale field experiment involved tens of thousands of applicants and highlighted AI’s ability to conduct more relevant interviews, though some challenges like technical issues and applicant aversion were noted.
A groundbreaking study conducted by researchers from the University of Chicago Booth School of Business and Erasmus University Rotterdam has unveiled compelling evidence that artificial intelligence (AI) agents are significantly more effective in job interviews than traditional human recruiters. The comprehensive field experiment, involving approximately 67,000 to 70,000 job applicants in the Philippines, demonstrated that candidates interviewed by AI were 12% more likely to secure a job offer.
The research, led by Luca Henkel, Assistant Professor at Erasmus School of Economics, and Brian Jabarian, a researcher at the University of Chicago Booth School of Business, also reported an 18% increase in job acceptances and a 17% (or 16% in some reports) improvement in employee retention during the crucial first month of employment. These findings suggest a potential paradigm shift in hiring practices, particularly for high-volume roles such as those in call centers, healthcare, IT, and industrial sectors.
Applicants in the study were randomly assigned to interviews conducted by human recruiters, AI voice agents (referred to as “Anna” in some accounts), or given the option to choose between the two. A striking 78% of applicants, when presented with a choice, opted for the AI-led interview. This preference indicates a growing comfort and perceived efficiency among job seekers regarding AI in the recruitment process.
According to the researchers, AI interview systems excelled by consistently covering more job-relevant questions and avoiding the fatigue that human interviewers might experience. This led candidates to provide more articulated and pertinent information, ultimately improving recruitment choices. Brian Jabarian emphasized the need to “move from the ‘possible’ discourse to the hard-data discourse, so we don’t lose our rationality.”
Despite the overwhelmingly positive outcomes, the study also highlighted some challenges. Approximately 5% (or 3.2% in some reports) of applicants refused to engage with the AI, citing a preference for human interaction or finding the AI less natural. Additionally, technical difficulties occurred in about 7% (or 8% in some reports) of AI-led interviews. It is important to note that, in all cases, the final hiring decision remained with a human recruiter.

Experts suggest that these findings underscore AI’s potential to enhance efficiency and job matching. The cost savings associated with automating initial interview stages could be substantial, depending on factors like company size, recruiter wages, and job nature. The study advocates for thorough evaluation of AI systems before widespread implementation, ensuring that the benefits are fully realized while mitigating potential drawbacks.
