No need to be nervous. If they called you to interview, you are basically a shoe-in. As long as you don't completely bomb the written, talk to the recruiters and show them someone can get along with you for four days in the cockpit, demonstrate at least a mediocre scan in the sim, and don't lie about anything on your paperwork and you will be getting a call for a class date. We need people badly. Do you live in one of the three bases or plan to commute to CLT? There's a bit of a backup right now for CLT, and commuting to TYS or DAY for reserve is not fun.
