UCHealth interview questions

Denver Metro Area, end of April/early May 2023. TLDR; experience was fine overall, but in the end, I was offered $20/hour. I tried to negotiate since the posted range was $19-$24, was told his "hands were tied," and I declined the offer. I first spoke with a recruiter over the phone. It was VERY standard, just asking about availability, schedule, etc. I asked questions about the role, expressed my skills and what I anticipated the role to be like. He was impressed and shared that he thought I'd do very well in the interview. I was scheduled for a virtual interview next. The interviewer was really nice, great experience. She went over what locations I could work in, any time off I might need, etc. Then she asked me a bunch of behavioral interview questions. Tell me about a time when... conflict with a coworker, dealing with a difficult customer, learning a new computer system, etc. There were 4-6 questions. She gave me an opportunity to ask questions and told me they'd be in touch shortly. Later that day I received an email request to submit 5 references into their online system. It sent them an online survey of some sort. That same day, I got a call from the recruiter offering me the job, pending references. I was offered $20/hour. I asked for three business days to think about it and to make sure my references had a chance to respond. I called a couple days later and tried to negotiate a higher wage. The posted range was $19-$24. The minimum required experience was "none." Preferred experience/skills was customer service, working independently, assisting patients check in, insurance verification, etc. I don't have a lot of formal healthcare experience, but I have 9+ years of customer service experience in a variety of roles, 4 years of HR experience, and 2 years tech industry experience. I also have a B.A. I was willing to take $23, maybe even $22, because I wanted to start a long-term career with UCHealth given the growth opportunities. I'm flexible with my schedule and with the location I travel to. I made my case to the recruiter and he said his "hands were tied." I politely declined, it's just not a sustainable wage in this area. Also, why post such a wage range if there really isn't a range? Just an FYI for people interviewing! Maybe ask about wage upfront!
