Hey cckat! I know exactly how you feel as I was in the same bingle myself! What I did was I pulled my previous cabin crew knowledge and came up with a question that was probably more internal then anyone who hasnt been a Flight Attendant would have thought of for e.g "Regarding your inflight training, are you paired with an actually inflight trainer, or is this a job that the SFS takes care of, and how long until you are checked to line" The video only really covers the surficial side of the job.Your lucky because you will be able to think about questions that are more internal, and you will probably come up with heaps....and it can also add a fresh approach then hearing the same stuff they probably hear over and over again
Best of luck!!!
