AI Phone Screening vs Traditional Interviews: A 2026 Cost-Benefit Analysis

In 2026, the hiring landscape continues to evolve, with staffing agency owners grappling with the decision between AI phone screening and traditional interviews. A surprising statistic reveals that 72% of candidates prefer phone screenings over in-person interviews, citing convenience and efficiency. This shift highlights the need for staffing agencies to reassess their recruitment strategies. This article delves into a detailed cost-benefit analysis to help you make an informed decision about which approach to adopt, considering real numbers, specific metrics, and industry examples.

Understanding the Cost Dynamics of Traditional Interviews

Traditional interviews often incur hidden costs that staffing agencies might overlook. According to a 2026 study, the average cost of conducting a traditional interview is approximately $300, encompassing expenses such as scheduling, interviewer time, and candidate travel reimbursement. With an average of 10 interviews per hire, this can total up to $3,000 per hire. Moreover, the average time spent on each interview is around 45 minutes, leading to a significant time investment.

Key Limitations of Traditional Interviews

• Time-Consuming: Scheduling and conducting interviews can lead to delays in filling roles, with an average time-to-fill of 42 days.
• Subjectivity: Traditional interviews are often influenced by bias, affecting candidate selection.
• Limited Reach: Many candidates may not be able to attend in-person interviews, narrowing the talent pool.

AI phone screening technologies have emerged as a cost-effective alternative. NTRVSTA's AI phone screening solution, for instance, reduces screening time from 45 minutes to just 12 minutes per candidate. This efficiency not only accelerates the hiring process but also significantly cuts costs.
