Which of the following is an example of selection device reliability?

In the context of selection device reliability, the primary focus is on the consistency and dependability of the measurement tools used to evaluate candidates. The scenario where a superior job performer received a low interview score from all five independent interviewers demonstrates a lack of reliability in the selection device—specifically the interview process.

The reliability of a selection device is often assessed by checking whether different interviewers arriving at varying conclusions about a candidate's potential can influence the reliability of that assessment. In this case, multiple independent interviewers consistently rating a top performer poorly indicates something is likely flawed about the criteria being used or their application, thus highlighting reliability issues. This consistency in scores, even if negative, points to the importance of ensuring that selection devices yield results that are not just accurate but also consistently applied across different evaluators.

The other options may showcase different aspects of assessment but do not illustrate reliability in the same manner. For instance, having a candidate perform poorly in both tests and an interview demonstrates a potential correlation between assessment methods rather than their reliability. Similarly, conducting all assessments with the same interviewer may suggest bias rather than reliability. Averaging scores from multiple tests could lead to a better understanding of a candidate's abilities but does not inherently ensure that the devices themselves are reliable
