Rémy Cointreau USA interview questions

I was asked to come at a time I initially said I could not do because of work but wound up taking a half day because it seemed like an interesting position. After meeting with their HR representative, I was told to wait for those in Finance. After five or so minutes of waiting, the HR representative approached me to say that there was a meeting that they just "had to attend" and could we "reschedule"? As unprofessional as this was, things happen, so I said absolutely and she told me they'd be in contact by the end of the week. That was over a month ago and after numerous phone calls and emails, I still do not know what is going on. I decided to withdraw my name as if you're going to treat an interviewee this way, how will you treat me as an employee?

1st round phone interview with HR. Asked fairly basic questions and answered any questions I had. HR was comfortable and easy to talk to. Said her notes would go to hiring manager to review after our call. Waiting to hear back
