It was pretty easy just be prepared to have at least 4-5 examples of ways you've helped customers. Personally I come from a airline background and the lady interviewing me knew that, I felt pretty confident with my answers and I even used STAR method on all my examples. Sold the stapler they ask you to sell at the end and always ask how they are going to pay for it. It will help :) The lady that interviewed me I felt she discriminated against me. She even voided my application before all the hiring was done!!! There was another supervisor that was in our interview and she said I was the best interview that whole day. I will be writing Delta Airlines about this matter and how I feel it was unfair.
