This document provides an introduction to the Myers-Briggs Type Indicator (MBTI) personality assessment and the Strong Interest Inventory (SII) interests assessment. It defines personality and interests, explaining that the MBTI and SII measure inherent preferences rather than skills. The MBTI is based on Jung's personality theory and measures preferences in four dichotomies: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, Judging/Perceiving. The SII compares individuals' interests to occupational themes. Both assessments can provide insight into career fit and exploration rather than selection.
