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.

It was nice and smooth and very intuitive. I liked how I had help from the website to prepare for the interview and so I was able to fully explain my previous experience.
