First thing I would advice is read the email you get thoroughly. On the email they will talk about assessing you on 5 behaviors in the questions. Think about your examples before hand they literally question you on each one. These examples don't even need to be work related but helps. The interview I had they didn't look at a CV they are looking how you will fit into the group, so make your answers relatable. Ask them questions about the happiest and most important day they have had working for the company? Remember as much as they are looking for a customer member, you're also looking for a positive work environment.

I had a very positive interview experience with Co-op. Syed Hussain was kind, patient and welcoming from the beginning. English is not my first language, and I was nervous, but he made me feel comfortable and gave me time to express myself. He listened carefully, treated me with respect and created a friendly atmosphere throughout the interview. I truly appreciated the opportunity and left the interview feeling confident and valued as a candidate.
