I do recall one job application where they made me take a personality test as part of the interview process, I am not sure if it was MBTI or not to tell the truth. It was before I was personally interested in it. This was the same place where the interviewer asked me about my hobbies. When I said I liked to read, he made a face and laughed and accused me of lying, saying that no one likes to read for a fun.
I do think it ought to be a personal tool for self-development. I am extremely disturbed by the idea of it being pushed on school children or forced in the workplace.
Edit: I took the MBTI as part of a voluntary career development counseling program my last year at University. It is used by Universities here in the USA.
