Don't put too much emphasis on any form of personality or aptitude test.
In my 31 years of flying,i have come across all sorts,some of whom i would never expect to be in charge of an airliner,quite alarming really.
Aviation,although highly regulated,has the same cross section of humanity as any other profession.
Total professionals,extroverts,introverts,religious zelots,aetheists,alcoholics,manic depressives,you name them,you will meet them.
The one trait you will need is to be tolerant and remain calm,when a colleague is driving you to distraction.
If you work for a major outfit,chances are you will never fly with them again,or at least for a few years.
