Last week, we showed you how to upgrade your selection process using HR Technology. In case you missed it, check it out here. Now, it’s easy to list the benefits HR software supposedly has to offer, but based on what exactly? What’s the reasoning behind those benefits? Valid questions, and the reason why we wanted to delve into some of the science behind the funnel we sketched out.

Part I: Thorough Testing

In itself, having candidates do some sort of assessment is nothing new; the infamous pattern recognition test and number series have been around for quite some time. And although both assessments can add value during a preselection process, they don’t give you the full picture when it comes to an applicant’s personality, skills and aptitude.

As stated last week, ideally you assess personality, intelligence, skills required for the job and situational judgement. Today, we’ll have a closer look into the scientific reasoning behind these tests and how they enhance each other.

HEXACO Personality is important when it comes to recruiting people to join your company. A person’s character tells you a lot about their work ethics, their sociability and will help you decide whether or not someone will fit in your company culture.

Personality is testable and the HEXACO personality framework is one of the most valid testing methods out there. It’s also the one we use for our preselection tool TalentPitch. This is how it works: an applicant’s personality is assessed on six different dimensions, each dimension having four facets. Honesty, Extraversion & Conscientiousness are examples of a dimension. If we pick Honesty and look at its four facets we have Sincerity, Fairness, Greed Avoidance and Modesty.

A minimum of 60 questions is required to get a reliable prediction about a candidates personality framework, but versions with 100 and 200 questions are available as well. And logically, the more questions you ask, the more reliable the personality profile you will get.
