You're probably not going to appreciate my reply, but what you ask is precisely the reason we took the DEC command selection process back "in house". If everyone learns the interview questions parrot fashion and can fly the profile with their eyes shut, then what are we really getting?
In the past, people got job offers without being adequately probed but when they started their Sim training, we'd find out "in a heartbeat" that actually they weren't as good as they'd have had us believe. What would then ensue was an embarrassing episode of hand wringing, bull$hit excuses, shifting blame onto others, failing LST's, extra training, poor base training, possible demotion to FO or ultimately termination.
If you're good enough to have been picked out of a bunch of applicants for an interview, then one would hope that given a bit of homework by yourself and paying attention to the brief they give you, then, if you've got a modicum of common sense and can fly to a standard commensurate with your supposed experience, then you shouldn't have a problem.
Ultimately we want to find out about you and see if you can fly so that, putting it bluntly, we don't waste our time. I would humbly suggest that now it's all been brought back "in house", that finding out what questions Fred Bloggs was asked isn't really going to help you as the interviewers are quite good at sifting bull$hit. And the profile is such that the instructors that do it can actually tell whether or not the person can fly; they need to as we've been stung too many times. But quite honestly if you CAN actually fly, it's really not that hard. Just be yourself, be honest and fly accurately. Best of luck.
