The Myers-Briggs Personality Type Indicator was developed during the Second World War to determine personality types and the kind of jobs suitable to them. Now seven decades on, several sophisticated assessment tests are conducted industry wide to determine best fit for respective organizations. A formal hiring process I used by around three-fifths of firms as per business intelligence firm Aberdeen Group. In fact, market research conducted by Deloitte clearly states that this assessment industry has grown by nearly forty percent over the past five years. More than just skills and behaviour, likely consumer assessments are scored by Baltimore based Pegged Software that caters to the health care industry. Using this, top performers can be modeled. Also roles can be clearly defined based on organizational requirements.
