How much does HR really believe in personality surveys?

From experience in some big companies, they can rely on questionably scientific pop psychology tests like Myers-Briggs or Insight. If anyone in the place got brains, it's not taken seriously.

It's glorified horoscope and not considered serious by any scientists.

.

depends on whether they're educated
but by and large I'd say only low level managers at gas stations believe in personality exams.

it was a joke when I was young.

'just say what you think they want to hear'

@atheist sometimes it's to listen to your concerns and use them against you XD

They need something to look like they are working

You all bring reasonable points. I had to answer a short survey filled with questions like "Choose the term that most describes you and the one that least describes you among these 5 options"

I got a 10 page pdf back showing my "results" and while some of it was accurate, most of it was completely off or very exaggerated.
