Should I go to this job interview tomorrow or not?

So I currently have a position as Asset Protection Associate at Walmart that pays $8.95 an hour. I have an interview tomorrow for a Billing Clerk/Office Assistant position at Cooper Tire that pays $11.00. I am not really concerned about the money. The Cooper Tire position works a 2-2-3 schedule, idk if that's good or not. But I've always wanted an Administrative position. My dilemma is: I have an interview next week for Medicaid Specialist and I don't want to waste anyone's time by going to other interviews because the Medicaid position is the 1 I really want. I've only been at Walmart for a month, is it going to seem like I'm job hopping or what? Idk what to do, really confused
