The Myers-Briggs Type Indicator (MBTI) consists of 16 personality types, each represented by a combination of four letters, such as INTJ, ENFP, ISFJ, etc.
Without knowing the specific characteristics and traits associated with the "XYZ" type, I cannot provide signs that someone has this personality type. Additionally, "XYZ" is not a recognized personality type within the standard MBTI framework.
If you are interested in understanding the signs or characteristics of a specific Myers-Briggs personality type, feel free to ask about one of the 16 established types, and I'll be happy to provide information on that.
