Congrats on the interview. I've been with AirShare for almost 10 months. I'd be glad to answer some questions to help you decide if its somewhere you'd like to be.
Even though this sounds very cliche' my only tip for the interview is to be yourself and use a napkin at lunch.
The schedule isn't all that bad, it just takes getting used to. Some months are busier than others.
I'm only flying Phenom 100 and here is a breakdown of my past few months.

This is a good company to work for. When your on the road you get to pick your own hotels and eat where you want. Meal allowances are $15 breakfast, $15 lunch, and $30 dinner. Occasionally you'll have some layover days and get to have some real fun on the road. Maintenance is top notch. When/if something breaks you don't have to worry about writing it up. You will not get yelled at or told to write it up in base. Coming from 135 freight this to me is amazing haha.
