Macy's Office Associate - PT interview questions

Applied online and the interview was arranged through their recruiting software, which means I talked with no one on the phone. Had several emails asking me to be sure to advise them if I couldn't make the interview. Day of the interview, waited for 40 minutes before someone walking into the office asked me if I had been helped. After overhearing the office staff discuss their scheduled interview times (no one claimed the 2:00 pm interview, which was me), someone came out and said she'd interview me. Interviewer was from a different department and she had no openings, but explained that the person who was supposed to interview me was too busy. This begs the question: Why am I here? Interview questions: Why do you want to work at Macys? Do you have any sales experience? What would you do if you saw an employee steal something? Typical retail behavior-based questions. After she was done asking questions, I said I was there to interview for a part-time office position. With a wave of her hand, she said that position had been filled. Then she asked me about my availability to work and I showed her the printout of what I filled out online for days/hours I could work. She suggested a couple of positions that might fit my availability and would forward her resume notes to a hiring manager in the store. Two days later I got an email from Macy's computer saying that my availability did not match the office assistant work days/hours. Although no interview is a waste of time because I always learn something from it, this interview was insulting. A five minute phone call from the office assistant hiring manager would have cleared up my work availability fit for that position, even if the computer couldn't. Instead, that hiring manager (for the office assistant position) wasted another department manager's time and my time because he/she was too busy. I guess that's what happens when a computer determines who's qualified to perform a job. The more time you save not looking at someone's application, the more time you can spend wasting someone else's time. I wasn't impressed.
