The only employment tests I have ever taken was at a jackass employer Reynolds & Reynolds... the stuff everyone in a backroom with computers where you do multiple choice questions with time limit for each (~50 questions each, about 5 sections) on the following subjects:
1) Patterns (IE: The one's where it has a triangle in a square, and in each square the triangle is rotating. What is next)
2) Simple math although as you continue it becomes harder. By harder I mean instead of being able to do 6x8 = 48 in your head, you start having to write out long division and it takes way more time.
3) More patterns
4) One other one I can't recall.
5) Long word problems (By long I mean ~6 sentences with technicalities) that involve math to solve.
All of which NONE was based on the job, industry, etc... Pathetic. I honestly wonder the legalities of such 'testing' for employment. I can do math - however the problem I have is the massive time limit on all of the sections. Hell, my fiance comes from a different country and doesn't read English fast (from what I get, she doesn't have the power to skip over assumptious words) - she was approved for extra time on tests like the SAT yet is incredibly smart. My handwriting is ugly and slopping long division on scratch paper while reading word problems is absolutely insane to justify workability.
