It's quite easy process and there is nothing to be feared. if you know stuff explain it honestly. Do not lie ask for initial training politely and they may offer it.

Fairly informal, lasted around 10 minutes. Was asked about my experience, working in a team, status for working in Canada (as I'm over on an open work permit). Was also asked about salary expectations and said I was happy with the range stated in the advert ($18.60-23.50), but was then told it would be Ontario minimum wage ($17.60)... The job was just stated as part-time but sounded like a zero hours position from the interview, so definitely wary about applying for future part-time roles here again, or at least at the Prescott branch...
