It just goes to show that it doesn't matter if someone screws around with you so long as you've got your head screwed on the right way.
To be sure, though, I remember reading that those with "the right stuff" to be astronauts tend not to be mavericks. Rather, they tend to be people who remain extremely calm under pressure, a quality that comes with experience no doubt, but some naturally fare better than others. However, they also tend to be anal-retentive, with a keen eye for details. I suppose that's what the interview was designed to discover.
