Interviewer Illusion

The interviewer illusion describes the tendency to people who are interviewing an individual to overrate their ability to interview and choose the best candidate. People normally feel that they can discern information about an individual very well and are more likely to overrate their instincts or 'gut feelings' about who is the correct candidate.

Cognitive biases can alter the perceptions of an interviewer along with the mood and preconceptions that the interviewer has. This phenomenon can occur due to the interviewer looking back at previous hires - in business, for instance, they are more likely to follow the careers of the successful people they hire and that makes their interviewing skills seem more proficient than they actually are.
