Interview at Hollister (Fragen)

Hi everyone! So I applied (as a joke kind of) in Hollister as a Brand Sales Associate a week ago and they emailed me last week I have an interview. So here I am bisschen anxious and I just would like to know what kind of questions do they ask? The job ad was both in German and English but I assume the interview will be in German correct? And I don't know, if you worked in Hollister, any other things that would help me prepare myself, thank you! 😭🥲
