Sands Inn & Suites interview questions

Had a pre-screening phone call before being offered an interview a few days after. When I arrived, the manager informed me no one told them that they had an interview. She asked me what I was looking for, to which I responded with everything the listing offered (full-time, benefits). She then informed me that she already filled the position. Overall, very unprofessional. I do not blame the manager, but HR should have been communicating with them.
