OPI (Occupational Personality Inventory) is an advanced psychometric that is published by Kenexa, the World’s second largest human skills testing organisation.  OPI is a complex tool that looks at 25 specific personality traits within the workplace and is based on Karl Jung’s widely accepted ‘big-five’ model of personality.  OPI is a self-report questionnaire, i.e. it is completed online by the candidate, and provides an in-depth profile that can be used for both recruitment and development.  OPI typically takes around 45 minutes and is 250 questions where the candidate are presented with behavioural statements and are asked how much the statement refers to them in the workplace on a scale from 1 (not at all like me) to 5 (very much like me)
