I work for a company in the legal recruiting industry (https://hireanesquire.com/) and we've been trying to tackle some of the biggest issues with recruiting -- albeit specifically for the legal industry.
At the end of the day, our goal is to create successful job placements. We've learned that there is surprisingly a lot of science in I/O psychology behind predicting job performance based on personality traits [0]. We've been developing an assessment system with a behavioral psychologist to measure personality traits that could predict a successful job outcome. To be honest, I'm surprised this hasn't caught on with the recruiting industry already. It's been working out well for us and I would expect to see more of this across different industries in the future.
