    The question in the first paragraph comes from a test called the Kiersey Temperament Sorter. It is an attempt to discover how people solve problems, rather than what they know. This is often called an aptitude test.
    According to Mark Baldwin of Alliance, many job applicants in China are finding this type of questions difficult "When a Chinese fills out an aptitude test, he or she will think there is a right answer but they may fail because they try to guess what the examiner wants to see."
    This is sometimes called the prisoner’s dilemma. Applicants are trying to act cleverly in their own interest, but they fail because they don’t understand what the interviewer is looking for. Remember that in an aptitude test, the correct answer is the honest answer.
