Usually a redbird at Daytona. If I am remembering correctly, it's at Phoenix East. If you can, I would recommend flying a couple of hours in one getting used to how it handles. You will shoot an ILS to mins more than likely and go missed as published. As far as the tech, be familiar with Jepp plates. You don't have to be an expert but just be familiar with them. Understand the briefing strips and how to brief as you'll be asked to brief a plate. Know your typical airspace and cloud requirements along with weather mins and alternates etc. Basic stuff. They are trying to get a feel for where you are and where your head is as well as your level of preparation. There is no trickery or hidden agendas or gotchas. Pretty straight forward. They want to see if they can spend a week with you on the road essentially. Getting a feel for you and your character and how you act and your attitude. HR is basic questions. You still need to be prepared. Don't go in blind. Dress business casual. Slacks and a button down shirt with or without a tie is my recommendation. I think a suit is overkill. They'll be in a polo and slacks doing the interview most likely.

Good luck.
