We're glad to hear you left the test feeling confident (ie. you found it super easy/straight forward). One caveat to keep in mind with CASPer is that the test is anything but straightforward. An SJT that may "seem" straightforward, typically isn't.
Notice that on the official takecasper.com under the following FAQ, "Do I need to Study for the test?", the response is very vague, "The general literature suggests that situational judgment tests (SJTs) are relatively immune to test preparation, i.e. that coaching is unlikely to provide benefit." The general literature actually suggests that behavioral SJTs such as CASPer ARE susceptible to faking and coaching effects. With CASPer, applicants are generally left in the dark. With CASPer, applicants are not explicitly provided with a roadmap of the personal and professional characteristics assessed etc, and combined with the fact that applicants do not receive a score, it's easy to see why this test is different than other tests, that are more transparent.
CASPer answers are rated on a likert scale by raters (all done by people, not by a machine) and the results are used to rank your candidacy. If you rank poorly, it hurts your chances of moving on to the next stage in the process.
