Any store loves to hire people who are passionate about their company. Good customers are your best advocates, so it's a great idea to turn them into dedicated employees. Now is your opportunity to share any specific customer experiences you have had there. Be sure to tell the interviewer how frequently you shop at their bookstore.
"I frequently shop for books for myself, and others, at your bookstore. I appreciate that you offer free coffee to keep me shopping for awhile and have the latest selection of books that interest me. Your gift section is great as well. I would say that I shop here at least twice per month."
Entry Level answer example
"I have shopped here many times before and am a big advocate for supporting local business. Every experience in your bookstore is positive which is why I am applying here. Your customer service is excellent, and your coffee shop makes the best macchiatos!"
Experienced answer example
"I shop for books here probably once per month. Your customer service comes through when needed, which is what keeps me coming back. I once custom ordered a book from your store. There was an issue, and the book did not arrive for six weeks. Your team went above and beyond in keeping me informed and providing 20% off when the book finally arrived. That level of customer care is not something you can find on Amazon or elsewhere. It was the personal touch that keeps me an avid customer."
