It was really easy, very basic questions were asked. Just be yourself, be confident. The interviewer told me about the duties to be performed, his past experiences with customers and how to behave with the customers.
I applied in-person. The process took 2 weeks. I interviewed at Rabba (Toronto, ON) in Feb 2016
Interview
It's was pretty easy, I just had one interview where the ask basic question about my experience with customer service and my availability, it is a 24 hours store so if you have a flexible schedule it will work in your favor.
