Which of the following statements about panel interviews is true?

Panel interviews are designed to involve multiple interviewers who each bring their own perspectives and expertise to the evaluation of a candidate. This multi-faceted approach allows for a more comprehensive assessment, as different interviewers may focus on varying competencies or traits that are relevant to the job role. Each panel member can ask questions and provide feedback based on their individual expertise, helping to ensure that the candidate is evaluated from multiple angles. This can lead to a more balanced and fair decision-making process regarding the candidate's suitability for the position.

The other statements do not accurately reflect the nature of panel interviews. For instance, stating that only one interviewer is needed undermines the fundamental concept of a panel, which is defined by its use of multiple interviewers. Saying panel interviews lack a structured format is also misleading, as many organizations apply a structured approach to maintain consistency and fairness in their evaluations. Lastly, describing panel interviews as less formal than one-on-one interviews does not typically hold true, as the presence of multiple interviewers usually creates a more formal atmosphere due to the collective seriousness of the assessment.
