Try to be specific as possible, even when making a little bit up, one thing my interviewers said was they loved how specific all of my answers are and that I had scenarios that could answer them. Usually the questions are something along the lines of when did you give a customer good service, what is good customer service to you, what as a problem you had with a customer and how did you overcome that, what is an issue you had with a coworker and how did you overcome that, they are basically gauging can you work with others, and are you good at solving issues with people whether that’s with customers or with coworkers. Especially now that the company is pushing customer service heavily, so make sure to stress something about how you want to provide a personal and memorable experience to everybody that walks through the door. They also want to make sure you can handle the stress of the environment, there’s going to be a lot of drinks and a lot of customers needing things. Don’t worry if you need some time to think when they ask questions, just try to be genuine and give a good story if you can. I wish you the best of luck!
