Which method is commonly used to assess the reliability of an interview process?

The method of comparing the ratings given to candidates by multiple interviewers is commonly used to assess the reliability of an interview process because it establishes a level of consistency across different evaluators. When multiple interviewers provide ratings for the same candidates, their assessments can be compared to see if they align. A high degree of agreement among interviewers suggests that the interview process is reliable, as it indicates that the evaluations are not heavily influenced by individual biases or subjective interpretations.

This method helps to identify whether the interview criteria are clear and consistently applied, contributing to a fair and objective assessment. In contrast, relying on a single interviewer's ratings can introduce personal bias and variability into the evaluation process, leading to questions about its reliability. Other methods, such as conducting personality tests or analyzing hiring trends, do not directly measure the consistency of the interview process itself and therefore do not effectively assess reliability in the same way.
