i think all series of the dash are either exactly the same or very similar in the cockpits. no, you'll be sitting in the right seat, i'm sure you know piedmont is practically begging for f/o's and will give just about anyone with a solo cross country endorsement a job, but as of right now they're not hurting for captains, so no left seat during the sim. i wouldn't study approach speeds or anything like that for the sim ride, you would just be wasting your time, and they tell you roughly what speeds and what not that you will be shooting for anyway. same with torque settings, a captain will be flying with you in the sim and will set up all radios, tune identify and everything else for you including the torque, they will tell you before the sim that if you want to go faster, tell the captain more torque, slow down, less torque, simple as that. they're are only looking for basic insturment skills during the sim so don't sweat it too much. hope this helps, good luck with the interview.
