ACU-Serve interview questions

Received an email followed by a timed test. Two weeks later, scheduled interview - was told webcam on is mandatory. Day of interview arrives, I'm the only one with the webcam on. Asked for a general pay range (so I could determine if going further in the process was even worth it for me) and they got snobby with me. Very unprofessional.

I had a teams interview that was scheduled for 30 minutes, but lasted more like 45 minutes due to us having an engaging conversation. The interview went great and the person interviewing me explained in detail that what they were looking for was exactly what I had been doing for five years. I explained how I had gotten promoted every year while working for another RCM services company, and that I had dozens of references available that I could send them. They also had me take a test before hand, and the person interviewing me told me that I got a 91% on that test. The interview candidly told me that this position was important to hire for, but nobody on their current team was good enough to promote into the role. The interviewer asked me for my salary preference which is hard for me to answer because I am essentially just desperate to live and am willing to take virtually anything at the right company. I was most recently earning over 100K in a similar position as this, so I put in 80K as im willing to take a huge salary decrease. The interviewer told me that since I had put 80K and the management team still wanted to interview me, that it must have been fine to them. The next day the interviewer emailed me and told me that 80K was too much actually so they would not move forward with me. I did reply and let them know that money should not be the focus here, and i would be willing to negotiate down to 60K maybe? but I was ghosted after that. I would avoid interviewing with this company as they do not seem to be lead by a competent executive staff.
