Oak Street Health Community Outreach Associate interview questions

I was contacted a few days after I applied online. The phone interview went well, basic questions. Next thing you know, they scheduled me for an in-person interview. I was very excited. This position seemed very interesting to me. After I left the interview I had positive vibes, the manager seemed to like me and promised that in a few days I will be contacted for the next interview. Also, I was told that I will be called for an interview at a different location since I am bilingual. A few days later, I get an email from HR saying they are no longer interested in me and yet a few hours later I received an email to schedule a phone interview. I was confused, and assumed there was some mistake. Here comes the day of a phone interview, I called the same recruiter who I talked to at the very beginning. He started asking me the same questions as the first time. When I told him, I have already spoke with him on XY date and was already interviewed by a manager he says: Oh, ok, good bye. I was lost, and politely asked about the positions I've applied that were very promising. He shortly answered, saying the position is closed and hangs up without letting me to say a word! Very rude and unprofessional.
