I'm interviewing for a basic sales associate position at a pet store. I've only had a job once before and it was an instant hire w/o an interview. I also only worked for a month. I'm so anxious about making a fool out of myself... I can't stop thinking about them asking a question that takes me off guard and my brain just shuts down. Or if I did get hired and was too stupid to figure out how to operate the register, even though that's what I already did for a month at my other job and I did fine. I'm also really anxious that they haven't realized I'm only applying for the summer and will turn me down since I can't work after college starts again. How do I stop panicking? What do I need to be prepared for? I just can't calm myself down no matter what
