Careful. Odds are high that you'd quickly get an interview call and CJO... so I wouldn't knowingly burn a bridge by turning down an interview or CJO. In this climate would they consider you again later? Yeah, probably but the industry historical norm would be to hold a grudge so why risk it?

Make up your mind before you submit the app. All the info you need to make the decision is available from various outside sources. You don't need to wait and see if you bond with the HR girls before you make the call, this is not that kind of job. If the bases, schedule, and pay work for you then the cube-dweller culture doesn't matter much... your office won't be a cube and it will have a window with a view.

Yes, this is a better use of your time than fishing for ULCC that you might not actually want to work for.
