I hate psychometric tests, they feel useless and for a long time I thought they were. But
Science says differently. and I'm not always a fan of companies outsourcing the initial recruitment process (I had a terrible experience with CTC now L3 doing just that), but it's a stretch to say that Kura know nothing about aviation. They are human factors experts and have an entire department dedicated to recruitment for the aviation indunstry, staffed by current airline pilots and similar folks.
It's an unfortunate part of the process. We just have to jump through the hoops and suck it up.
