Hi,
my experience with internship interview was simple they asked me scenario questions e.g how to deal with employees if there is conflict or medication errors e.t.c i had a few questions about what reference sources to use if i didn't know the dosage or was not familiar with a drug.I had some clinical questions on diabetes treatment drugs too.
My advice would be to be confident in what you answer, take time to think about your answers and imagine it as if you were already an RPH how you would handle your pharmacy, if its a face to face interview remember to appear proffessional.
I did not get a questionnaire but then again it was 2 years ago so things might have changed.
Good luck to you all and do not panic, if you made it through FPGEE you will pull through.
