Just generic questions you should be able to answer. If you're currently employed, they will ask why you're leaving your current job. Be prepared to answer that. Even if you have social anxiety, you could ace the interview. After the interview, they give you a tour of the warehouse before you make a decision to join. If it goes well, you could get a job on the spot, which is so rare in this day in age. Be sure you know what shift you want and know what the hours are.
