The Need for Hiring at Scale

Global companies like Hilton and Unilever recruit for thousands of roles annually—Hilton fills over 100,000 positions, and Unilever processes 1.8 million applications yearly (SHRM, 2025).

AI addresses these challenges by automating repetitive tasks, improving efficiency, and personalizing candidate interactions.
