Applied at Hardee's for Unknown

I have an in-person interview at Hardee's tomorrow at 2 PM, and honestly, this is one of my last resorts for finding a job. I don't have much experience to speak of, just some minor embellishments about babysitting and being a teacher's assistant. The location is super convenient since I can walk there, especially since I currently don't have a car. I'm starting college in the fall and really need to save some money for myself and my future. I’m feeling a bit anxious and would love some advice on how to ace this interview step-by-step. I had another interview at Taco Bell, but it fell through because my sister works there, and the manager who was hiring didn't like her. I also have a backup interview at Chipotle, but it's much farther away, so I'd prefer to get this job at Hardee's. I’ve received some tips from friends and online, like showing up a bit early, being reliable, and conveying my eagerness to learn. I plan to dress appropriately—clean and sensible clothes, hair pulled back, and to be polite and friendly. I just hope I can make a good impression and land this job.
