I hate assessment tests. Emploeyers have increased the use personality and aptitude tests to candidates in order to find the "right fit", but these tests flawed, usually under a time constraint (with several questions) and, sometimes, requiring a candidate to recall old algebraic formulas that he or she doesn't use--but that doesn't mean the person isn't intelligent. Also, many people have test-taking anxiety. I do. I always have. When I took tests in college, I bombed miserably. Even had to take basic algebra becaise my nerves were frayed and I am easily distracted (which I later found out was due to undiagnosed ADD).

Likewise, personality tests are flawed. Too often, you're forced to choose whether you'd rather be a sociopath or a doormat. You're also expected to be this golden unicorn that is charismatic and convincing ( without being that sociopath) and intelligent and warm. Also, suspect that if it's between you and an incumbent, if you're below the "Golden Unicorn" Score, which lets say is a 95, your resume is likely to be tossed in the "junk mail", if your competitor tests better than you.

It is very frustrating and not too mention time-consuming to take these tests. Also, according to an article I saw on Quora, some questions are actually ones that are likely to be illegal because they are related to mental illness, which is protected by the ADA.

This all sucks because really, it's just boiled down to employers using these tests as another way to "weed out" applicants and keep the process moving fast. However, they could be missing out on a really great employee.
