Why don't you let the kid interview guys? Hiring "mins" aren't set in stone... He's as green as can be, you're not painting a very positive picture for the poor kid.
Jake, go in with an open mind. It's important to not mislead or hide anything when it comes to airline apps/interviews. You're not the first to "misunderstand" how the process works and what's expected. I wouldn't worry about all the razzing you're getting on here. If you're qualified and fit the mold, you'll get the job. Either way, the interview will be a good experience. There will be plenty of hiring going on in the next couple of years, so chin up and best of luck!
