PDI Health interview questions

I applied on April 22nd and was emailed for an interview scheduled for May 7th. On May 7th, I received a text message that my interview must be rescheduled for May 13th (no other options were given). On May 13th, I logged in for my interview, and the recruiter never joined the call. When I emailed the recruiter, she was out of the office that day. I emailed the person listed on her out-of-office message, and a few hours later, I was told that she is no longer with the company and that someone would get back to me. I was then confirmed for an interview on May 22nd. I was told that I was interviewing for the role of the person who scheduled the interview (which is strange because she had a different job title). It turns out that it wasn't an interview; it was a 10-minute call to talk to me about the role and ask me one question: Why am I interested in working there? I was told I would be scheduled for an actual interview if they were interested. It is now June 3rd, and I have never heard back from them. This is not how a company should treat a candidate; This process was very unorganized
