Introverted persons have no problems with detailed work. They feel that detailed work is the first trench defence line against the cruel and merciless reality with its ruthless laws of nature.
Unlike extraverts, they will react to stress by withdrawing into themselves. They will, so to speak, try to solve problems individually. They will be more silent and absent-minded professor-like.
It is important not to confuse introversion with anxiety.
Introverted persons have their own inner strength, because they have thought things through. They can withstand stress longer than the very extraverted persons.
One must of course score on introversion or extraversion depending on the position in question.
It is obvious that if you go for a job as a salesman, then you must score well on extraverted, and if you go for a position as a caseworker in an IT development firm, you must score on introverted.
If you apply for a career position in one of the major international companies, it is wise to score well on extraversion. In this kind of firms extraversion is almost synonymous with leadership potential. They prefer handsome young men, who give a good experience, when they talk to them; it gives a sense of a streamlined modern organization.
