Organizations have been screening job applicants based on personality for years using behavioral assessments such as Pymetrics games, which measure up to 91 personality traits that fit into 9 different categories.

In fact, Shue said, “a ton” of companies already heavily use these more obvious estimates of someone’s personality, “they just haven’t been doing that from pictures of a person’s face,” she said. “I’ve known students who don’t get a callback after the behavioral assessment. So, presumably they were screened out based just on personality.”

Derived from a psychology framework, the Big Five personality traits (also known as the OCEAN model) comprise: Openness (curiosity, aesthetic sensitivity, imagination); Conscientiousness (organization, productiveness, responsibility); Extraversion (sociability, assertiveness, energy level); Agreeableness (compassion, respectfulness, trust); and Neuroticism (anxiety, depression, emotional volatility).
