Holland's vocational guidance test allows you to determine the most appropriate field of activity and profession, based on your interests and preferences.
The test was developed by the American psychologist J. Holland. He established a link between the psychological type of a person and his profession and developed a scale of adaptation of various personality types to six professional fields.
This application allows you to quickly and conveniently take the test, get the result according to the developed scale, as well as get additional help on each type of personality.
What is it for? When choosing a profession, you need to consider your professional type. If the profession does not correspond to your personality type, the work will be given to you at the cost of considerable psychological stress.

I wish you success!
