Prepare by conducting a “job analysis”
Interviewers should consult with at least one “Subject Matter Expert” to generate a specific list of the most important aspects of the job and what is required to perform it successfully. Not only will this make the interview more relevant to the job, but job candidates and interviewers will also view the interview more positively.
Prepare questions in advance
An interview format in which all job candidates are asked the same specific questions further ensures that information obtained from candidates is relevant and comprehensive. This method also helps avoid irrelevant content. Asking uniform questions makes candidate responses more directly comparable.
Prepare to be flexible
What if the interviewer asks a pre-developed question, but the candidate doesn’t provide enough information? Interviews that simply move on to the next question at this point, without leaving room for follow-up questions often do not collect enough information from candidates. Furthermore, both job candidates and interviewers perceive this format more negatively.
Ensure the interview isn’t too short or too long
Since it is important that all candidates get the same opportunity to answer the same questions — without feeling rushed — it is generally best to limit the number of interview questions. A good rule of thumb is to ask no more than four to six questions in a 30-minute interview, and no more than eight to 12 questions in a one-hour interview.
Focus on the interview during the interview
Despite what some experts recommend, the evidence suggests that soliciting candidates to ask questions too soon reduces the interview’s reliability. Candidates should only be solicited to ask questions after the conclusion of the interview, allowing engagement on a more personal level.
Include more than one interviewer
The use of multiple interviewers greatly increases the reliability of the process. Different interviewers in separate, subsequent interviews are more likely to agree on the right candidate.
Take detailed notes:
Note taking creates a professional atmosphere for the interview and makes a candidate feel respected, listened to and encouraged. And since human memory is limited, most interviewers can’t remember every candidate’s answer to every question. Making a set of specific notes for each interview also allows interviewers to be specific about why they came to certain conclusions about candidates.
