I completed interviews with my intended manager and HR about work conditions and salary, we had agreement on the particulars including dates, then the organization (multinational corporation purchased a Europan unit I applied to) mandated aptitude test, composed of some sort of mental abilities test and a personality test. "All employee must take the same test and reach a threshold". All from some external party sold their aptitude test services, used by the company for about 2 years as I understood (being a recently researched and perfected technique as I recall). I had a chance to see a practice test before completing the real one. The mental abilities test had generic IQ test like 'complete the sequence' but about half was 'calculate the sales figures of the hypothetical organization based on given situation' kind of tasks, in overall way too much for the allocated time, impossible to complete (testing the endurance against stress, ability to balance accuracy and pace I take, but I only reached about 1/4 being unpracticed in the topic). What?! Engineering position is tested by fast financial calculation? Then came the personality test, similarly with quicker than comfortable pace selecting most relevant answer of the three choices. But all were important depending on the circumstances (which was unspecified) and actually could, and in most cases should coexist (like what is more important to you, choose one: honesty, completing allocated tasks, client satisfaction).
I contacted HR saying that this is not a test that could measure me reliablty considering I have no practice in very fast financial calculations (can do slowly, but they emphasized the importance of pace with accuracy) and that I am forced to give random answers in the personality part, depending on what is my mood at the moment (basicaly mad about these idiotic tests). They told I must complete it and this is 'the base of allocating responsibilities and determining advancements in the company'.
I chose to withdraw my application instead (despite being without job for some months and the position looked promising). I do not want to work somewhere where they make this kind of across the board uniform and abstract tests the base of my evaluation (even if they just claim they do, since it is very difficult to imagine they could reliably do so).
