Personality Tests

I had a job interview where they gave me a type of “personality test” where I was to mark traits that I saw in myself, and ones that I thought others perceived in me. Then came the “Why am I good for this job” in my own handwriting. I felt like an old woman was going to come into the room and read my palm or some tea leaves.

Do many employers use them anymore? What’s the best way to deal with these type of “tests”?
