Walmart Customer Service Manager interview questions

The person up front sent me to the wrong place, I sat on a bench for 15 min until a manager saw me sitting with wearing business attire and assumed I was the job applicant. He took me to a room and pulled out my application that had a sticky note on it. He walked me down to another room where he sat me down and told me that even though they had called me to interview for CSM, there actually wasn't any positions open, and instead just offered me a cashier position after asking no questions and said that a CSM position would open up very soon and I could interview then.
