Just be yourself and have an interest in pets is a perk. Or owning your own pets or having experience with pets. The managers are super great at least mine are.
What is your biggest weakness? How have you dealt with negative customer interactions? What do your pets mean to you? What pets do you have? What experience in sales do you have? How would you deal with being independent and not having a manager always there to help you? How do you feel about traveling from store to store?
