I wouldn't worry about it, No1.
I think the idea is that the real you shows through, regardless of what you do, so relax and treat it as a jolly.
As I remember, a pilot is supposed to be a "normal extrovert". I've never heard of anyone not getting a job because of the results of one of these tests, and I've come across some pretty weird characters.
In fact, I'd go so far as to say all the pilots in all the bases I've worked were definitely very odd indeed.
Except me, of course.
