If your interview is with Gary, the recruiter as was ths case when I was hired then just relax and be yourself. He couldn't be a nicer guy and he just wants to make sure you'll be happy there. It's important to understand exactly what you're getting yourself into as it's not for everyone. There is a standard sim eval in a brand new Elite unit - the usual stuff and a simple written. It's all very basic but apparently still too much for some people.
You'll also meet with Ernsst, the D.O. also a super guy he want's to make sure you'll last long enough to be worth training. Nothing tricky is involved. Be prepared to sign a 6 month contract, however you simply have to return your $1000 bonus check if you leave early. I don't know about ORL but, I'd take anything to quit instructing. It's fun!
