If you get an interview, know Jazz's history. All the prior airlines that merged to become Jazz. When AC owned them, when they sold them. Know what Chorus is, know who the CEO is of Chorus and the President of Jazz. Know the bases, and fleet. They will ask all of the above.

Then just do your best and try to have a few scenarios from your hopefully 703 time so you have something to talk about. A lot of "tell me a time when" stuff in the interview. When they ask you tell me a time you made a mistake, don't be like "I left the chicken strips in the fryer too long"... give them a real answer. What you did, what you learned from it, etc.

Good luck. Jazz is a good place to work overall, just make sure you temper your expectations on the whole flow thing to AC. But if you go in with your eyes open you'll learn a lot and be at a pretty decent company with good scheduling rules.
