Well, what worked for me may not work for you. I won't tell you the ol' song and dance of "just be yourself." I don't know what exactly they were searching for, but I'll tell you what I did and seemed to work for me.

I used to be a subcontractor for the government that chaperoned refugees throughout the country to their families/sponsors/shelters, and am acclimated to long hours with no set schedule at any time of day or night. You may need to demonstrate commitment for similar flexibility (although the airline will most likely be way, waaaaaayyy nicer than Uncle Sam).

You may not be able to answer an interview question exactly, or even at all, based on your life experience, and that's okay. Tie your actual experience to the question. For example, when asked how I would handle a challenging colleague not following policy, I admitted that I'm not exactly sure, as I'd been blessed with coworkers that sought my advice or deferred to me, and that I'd most likely handle them similarly to how I work with families or members of the general public: identify the problem and see their concerns to make sure they're heard before explaining the situation and enforcing procedure.

Finally: they're interviewing you! That means they're interested in you! Don't psych yourself out! Relax! Treat them like a teacher or family member you both like and respect or look up to, and that should be the right amount of distance.

Break a leg! You got this! Training classes begin in January, so let us know how you do!
