RAT 5 & fireflybob ,
yep, been there done that too. Total and utter tosh, and like you, I was astonished at both who was accepted, & the excellent candidates (not including myself here
) that were dismissed out of hand.
It was a great money spinner for some folk though, and every few years a new iteration of it springs up & becomes the "gold standard" of selection procedures.
Totally totally meaningless, & they end up with the same spectrum of aces & turkeys as would be the case had they just picked names out of a hat at random.
