Being able to have a personal account of BC Hydro's services will help you assess what their company is like. When you're asked this question, the interviewer really wants to know what you think of the company from the customer side, and also wants to find out what you've heard or witnessed. If you aren't a customer or never have been, you can be an exceptional candidate by calling their office and inquiring about their services - even if you don't need them. It will get you familiar with the organization so that you can truthfully tell the interviewer about your experience with the company.
