American Medical Association Manuscript Editor interview questions

After inviting me for phone interview, the AMA stood me up, i.e., they just didn't call. About 45 minutes after the appointed time for the interview, I replied to the email inviting me to interview and said that I was disappointed that the interviewer could not keep our appointment and hoped we could reschedule. Perhaps the interviewer had a family emergency; I wanted to give her the benefit of the doubt. A few minutes later, she called and told me that the job had already been filled and I am overqualified anyway. I was confused by this. If they already made an offer to someone, why did they invite me to interview? And if they thought I was overqualified, why did they invite me to interview? Then, the interviewer asked what my salary requirements were for the nonexistent job and before I could refuse to answer such a ridiculous question, she said $90K was too much. Then, she gushed about excited she was to received my resume and how much great experience I have. Then she pressed me again for my salary requirement for the nonexistent job. I didn't respond with a number. Finally, she encouraged me to reapply because these positions turnover "all the time." Today, I received a rejection letter thanking me for our great "phone interview," and stating that they were pursuing candidates whose experience aligns better with the position.
