Interviewing for a Sales Professional job

Hello all, I am currently in process to interview for a respiratory position. Haven't had the phone interview yet.
Could anyone give me insight on what to expect in the PI then eventually the F2F?
What the best approach/angle to be successful during the interview process?
if there are any reps currently working as sales prof in respiratory, what is the day to day like? compensation?

Thank you for your help!
