There is a shop outside that says recruitment. What should I ask her when I go in?

I went in and asked the first staff member, with a slightly polite tone: Hello, is your store still hiring?

If it is the front desk or other staff, they may tell you who is in charge today. If not, they may have to wait. If so, they may have a chance to talk face to face.

If it is convenient, you can prepare a resume and briefly introduce yourself, so that the other party can only know part of his resume in a short time, get ready and dress neatly, and then organize language to answer the other party's questions.
