Personality tests are used wherever personality traits need to be included for a research objective or diagnostic decision making.
During my years of working in sales, the typologies according to DiSG® have helped me a lot to understand customers better and to adjust my communication as well as my behavior in a target-oriented way. DiSG® is particularly suitable for people in sales, in advising guests and customers, in complaint management, in teamwork or for the coordination of office and field sales.
ViQ® Visual Questionnaire, on the other hand, goes deeper. It shows hidden potentials and can hardly be manipulated due to the visual assessment. In my experience, ViQ® is particularly suitable for position assessments, development and aptitude interviews.
