Personality tests are a load of garbage in my opinion. I would be much more concerned about your ability to pass the exams, competently operate the aircraft, are you resilient enough to get through the arduous training course. Also, could you handle the pressures of being a pilot, early mornings, late nights, time zones, corporate pressures, being rushed, one thing after another going wrong all day......?
Thankfully, the world is full of different personalities and we aren't all the same, so you can't expect pilots to all have the same personality. Most experienced Captains should be able to separate the personalities that will fit and won't fit at the interview stage.... trying telling that to Human Remains though! A good way to figure out if you've got the personality, along with many other necessary attributes; is to find an experienced PPL instructor and learn to fly.
