What is one way to enhance objectivity in evaluations during interviews?

Both 1 and 3

The correct answer is option 4: Both 1 and 3

Objectivity in interviews is about reducing "gut feelings" or unconscious bias and replacing them with measurable data and consistent processes.

Using Rating Scales (Option 1): Rating scales require interviewers to assign a numerical value to a candidate's response based on pre-defined criteria.  Instead of saying "I liked their answer," an interviewer must decide if the answer meets the "Level 4" or "Level 2" description. This makes it easier to compare candidates side-by-side using quantitative data.

Following a Set Procedure (Option 2): This refers to Structured Interviews, where every candidate is asked the same set of questions in the same order. It ensures that every candidate is evaluated on the same playing field. If one interviewer asks about technical skills while another asks about hobbies, the evaluation becomes subjective and inconsistent. A set procedure minimizes these variables.
