One of the strongest trends in interview techniques is called B.D.I., or Behavior Descriptive Interviewing.
This type of interview technique was invented to improve employee retention. Too much time and resources were being expended in interviewing and training new employees, only to have to replace them because they were found to be unsuitable for the job.
Human Resources specialists called in to tackle the issue of employee retention and hiring suitability found that often the person who gave the best interview might be the most personable, but was frequently not best fit for either the job for which they were applying, or for the culture of the company.
Research soon showed them several interesting things. The most important of these was that past job behavior was the best indicator of future job behavior.
This led them to the second - the development of the technique of describing past job duties to show how they fit current job requirements, which is the key to behavior descriptive interviewing.
Large companies will often hire HR specialists to facilitate up-coming hiring. The specialists will exhaustively interview current key employees who already hold positions for which interviews will be held, about the activities they undertake in the completion of their job duties.
These specialists then compile and prioritize those activities into key job duties, and use them to produce interview questions.
The questions will then be used to interview potential employees. As this process can be lengthy and expensive, companies will often have interview questions compiled for most of the key positions in the company.
The behavior descriptive questions produced by this method allow the prospective employers to dig deeper than the simple comparison of past duties to prospective duties.
They allow for the employer to have a far more accurate gauge of what to expect from their potential new hire.
