What help do you need? The pt interview should be written in essay format. Ask questions like how the pt decided to become pt? Where did she/ he complete studies? What is her specialization? What kind of advice, suggestions does she give to clients? Are there any legal issues? Lastly what message would you like to give to new pts, etc. you can think of many other questions too.. Besides in assignments there are basic questions give.
there is nothing right or wrong... Just find a therapist to interview. I recorded my interview so that I can listen to it later.
hope this helps!
good luck
