What is the halo effect in interviewing?

• A. A cognitive bias where an interviewer overlooks weaknesses simply because they made a highly positive impression in one specific area.
• B. The tendency to overemphasize a candidate's negative trait after a poor interview.
• C. A bias that occurs when interviewers rely solely on resume buzzwords.
• D. The tendency to conflate enthusiasm with competence.

Answer: (A)

The halo effect in interviewing is a cognitive bias where a strong positive impression in one area causes the interviewer to generalize and rate other aspects of the candidate more favorably, potentially masking weaknesses. If a candidate is particularly articulate or confident, the interviewer might view their skills, reliability, or fit as stronger overall even if the evidence from past performance doesn’t fully support it. This aligns with the description of overlooking weaknesses because of a highly positive impression in a single area. The other options describe different biases: the horn effect is the opposite tendency to focus on negatives after a poor interview; relying on resume buzzwords is about superficial signals; and mistaking enthusiasm for competence mixes eagerness with actual ability. To reduce halo effects, use structured interviews, clear scoring criteria, and multiple interviewers to anchor judgments to observable evidence.
