My friend has taken the MBTI multiple times and almost always she gets a different answer. I have an idea of what she might be but I am not positive so I thought I might paint a picture of her to see if anyone has any insight.
In high school: She was on the honor roll, in national honor society, and in the debate club. She worked hard for her grades and was obsessed with flashcards to study with. She had a small group of friends, girls and boys.
College: She went to college for film (watching movies/collecting them is her biggest hobby) but dropped out because she was unsure if that's what she wanted to do and felt she was wasting money.
She is generally a lively person, always wanting to play games (board games, guessing games, etc.) and is pretty funny/sarcastic. She can be moody though and when she is in a bad mood she mainly just shuts down and only gives one word responese and such. Her room is usually orderly although cluttered with posters, records hanging from the ceiling, twinkle lights, etc. She has a huge phobia of being called on in class and can get pretty anxious in some social settings although she loved debate and when she's with people she's comfortable with, is loud and outgoing. She is currently working as a manager at a movie rental store and loves her job. Sometimes she spaces out in conversations and you have to say things a couple of times to her before she focuses on it. She always wears cute outfits, nice makeup and does her hair well.
Any ideas? If you need more specifics or feel like there is certain information that I could give that might offer more insight, please let me know.
Also, here are the types I know she has tested as: ENJF, INFJ, ESFJ, and ISFJ. So it seems as though F and J are constants.
