Yeah, I wonder how truly effective these tests are over more tradional means. Of course there has to be some type of evaluation process.
Like other parts of the selection process, one needs to navigate through the hoops the best they can. If one trips at one stage, take a breather, wait the required time, then reapply.
No need to take any of it to personal. Include some self evaluation in the mix too. Enlist professional help also when appropriate.
