Dillard's Visual Merchandising Manager interview questions

My first interview went well and was fairly quick, about 10 minutes in I was told that she was going to look for her store manager. After about 15 minutes she came back and asked me if I would be okay with waiting about 20 minutes to speak to the store manager. I said yes, no problem. I proceeded to wait 30 minutes before the store manager greeted me and took me to her office. After a few minutes of looking over my job history, asking detailed questions of each job that I have had even ones that are from over ten years ago, she asks why I want to leave my current job. I inform that I am looking for something closer to home and somewhere that can accommodate my needing Sundays off. She informs that Sunday availability is needed. I let her know that the position I applied for and was interviewing for stated Monday-Friday in the job posting. She then tells me that the position I was interviewing for was already filled. This was upsetting as I would have not been interested had I known this prior. I found this interview process to be misleading, unprofessional, and a general waste of my time.
