We use a proprietary tool consisting of a combined test examining: personality, dimensions of culture and diagnosing the reliability of the answers. In addition, we applied a unique proprietary solution “FRESH” and “DYNORM”, which deprives our solution of the problem of multiple alternatives consisting in progressive test obsolescence and mismatched norms. The psychological part is based on the IPIP/BFAS psychological test with 100 questions, adapted to the language of the user, normalized on more than 1,000 adults of working age. AC > 0.85, Omega > 0.86.
