The science behind Yobs

We are a team of HR practitioners, data scientists, and organizational psychologists working with world-class researchers to continuously validate and mitigate adverse impact from biases.

How it works

The Yobs API enables individuals to provide their responses to job-related questions in an audio, video or text format. Our scientifically validated assessment service then uses trained professionals and natural language processing technology to assess an individual's communication style, work style, soft skills, and the Big 5 personality traits.

Speach and verbal skills

The speaker's naturally spoken answers are transcribed into text automatically in 60+ languages. The content is then analyzed linguistically for word choice, sentence construction preferences, and more using natural language processing. We don´t do facial analysis for bias and privacy reasons.

Vetted for subconscious bias

Our models and datasets are constantly vetted for adverse impact that can arise from demographic, physical, linguistic, and accent differences between individuals. We nudge our clients towards I-O best practices such as structured vs. unstructured interviews, and emphasizing job-relevance of assessments, with intuitive software, assessment reports and implementation guides.

I-O principles to ensure job-relevance

We use best practices in industrial-organizational science to link our assessments to job-relevance. Our pre-built profiles are based on what is proven to make someone successful in a given role. Our bank of recommended questions are designed by experts to generate desirable variance in responses and results. We also perform local job analyses and local job validation to ensure our models predict success on the job.

99.99% quality with review system

Our API generates a confidence score for every report to help ensure the highest quality. Our team of expert reviewers, assisted by quality assurance tools, ensure that every report sent back to you is accurate.

We consistently measure and analyze potential gender bias and ethnicity bias in our assessments.

Yobs is fair and proven to be predictive of success on the job and reduce bias

The science of personality

Our API evaluates the "Big 5", the five most important dimensions of personality and soft skills, in accordance with the Five Factor Model (FFM)—a model that’s used by 85% of the Fortune 500 in hiring and training assessments and is the most accepted by the industry and scientific community.  It is also largely proven to be correlated with job success in many different occupations in consensus literature. In a validation study conducted by researchers in I-O Psychology, Yobs' Big 5 assessment of 500+ individuals was strongly, positively correlated with the experts' assessment of these individuals. Other technologies benchmarked, such as IBM Watson, significantly underperformed the Yobs API.  Click on each trait to learn more about how they may influence workplace success.
