How should interview panels be composed?

• A. A single interviewer for consistency.
• B. Panels selected by seniority only.
• C. Diverse panels representing roles involved, with a clear interviewer guide and calibration to maintain consistency.
• D. Panels consisting of external consultants only.

Answer: (C)

Dusing a diverse panel that includes representatives from the roles involved, together with a clear interviewer guide and calibration to keep scoring consistent, is the most effective approach. This setup ensures the interview assesses the actual needs of the job from multiple angles—technical capability, team fit, and workflow reality—rather than relying on a single viewpoint. A structured guide ensures every candidate is asked the same core questions and evaluated against the same criteria, while calibration sessions align interviewers on what high and moderate performance looks like, reducing variation and bias. This combination improves fairness, defensibility, and the likelihood of selecting someone who truly fits the role and team. In contrast, relying on a single interviewer lacks breadth and can introduce bias; selecting panels by seniority alone can overlook practical expertise and team needs; and using external consultants only may miss internal context and alignment with organizational culture and goals.
