What type of evaluation interview error occurs when an interviewer rates a candidate high or low on all traits based on a single impressive or unimpressive characteristic?

Explanation

• Halo Effect occurs when one positive trait (e.g., strong communication or physical appearance) causes the rater to evaluate all other traits favorably.
• Horn Effect is the reverse: one negative trait skews all other ratings downward.
• Contrast Error occurs when a candidate is evaluated relative to previous candidates rather than fixed job standards.
