The following is a list of common interviewing errors that can breach the validity and reliability of the interview: 1. **Poor Planning** – This often results in unstructured interviews, with minimal information to accurately compare candidates. The more unstructured the interview is, the less valid and reliable it is. 2. **Snap Judgment** – First impressions are key, but should not be used to judge an applicant. Often at times interviewers will make a “snap judgment” within minutes of meeting the applicant or even when they review their test scores or resume. 3. **Negative Emphasis** – Interviewers are most likely to remember and be influenced by the unfavourable aspects of the interview, and opinions can be more easily changed from positive to negative. 4. **Halo Effect** – This is when a positive first impression of an applicant causes the interviewer to view them with a positive bias, which distorts their ability to accurately rate the candidate. For example if the candidate has a nice smile or firm handshake they may be viewed in a positive light before the interview even starts. 5. **Poor Knowledge of the Job** – If the interviewer is not familiar with what the job entitles they will not know what type of person that would be best suited for the position. As a result, they will most likely inaccurately choose a candidate based off a stereotype of what they believe is a good employee. 6. **Contrast (Candidate-Order) Error** – The order that a person is interviewed can affect their rating. For example, a candidate may be viewed more favourably than they actually are if they were interviewed after a series of unfavourable candidates. 7. **Influence of Nonverbal Behaviour** – Nonverbal behaviour, such as more eye contact, head moving, or smiling can positively influence the interviewer’s view of the candidate, and can account for more than 80% of their rating. Studies show that the attractiveness and gender can also affect their ratings – the more attractive a person is, the more suitable they seem are for the position. 8. **Telegraphing** – This is when the interviewer is “telegraphing” expected answers to help the candidates respond correctly to the questions. It can be as obvious as asking a question like “This job can be very stressful. You can handle that right?” or as subtle as smiling or nodding when the candidate responds favourably after a question. 9. **Too Much/Too Little Talk** – Either scenario is not favourable because you will not be able to obtain the necessary information to accurately rate the candidate. This is why experts suggest using the 70/30 rule. Have the candidate speak for 70 percent of the time, and the interviewer the other 30 percent. 10. **Similar-to-Me Bias** – Interviewers tend to view candidates that are similar to themselves more favourably (i.e. candidates that posses the same demographic, personality, or attitudinal characteristics as the interviewer).
