How do organizations identify, assess, and hire top talent while navigating complex legal, ethical, and psychometric landscapes? This advanced doctoral seminar offers a rigorous exploration of the theory and practice of employee selection. Rooted in the industrial side of I-O psychology, the course critically examines the criterion problem, validation strategies, and diverse assessment modalities—from traditional cognitive tests and structured interviews to the frontiers of algorithmic and AI-driven hiring. Students will bridge the gap between academic research and applied practice, learning to design legally defensible selection systems, evaluate assessment fairness, and translate complex psychometric data into strategic, evidence-based organizational insights.
