One of the most popular is the Myers-Briggs Type Indicator, which asks a series of questions to determine which of 16 different personality types you are. About 88% of Fortune 500 companies have used this test to better understand their employees and new hires.
Myers-Briggs personality types are based on four buckets, which can be "filled" in one of two ways: introversion (I) or extroversion (E); intuition (N) or sensing (S); thinking (T) or feeling (F); and judging (J) or perceiving (P).
Your four-letter type is meant to help you determine your strengths and weaknesses in all aspects of your life, including work. This is how each type plays out in the office.
