Optum interview questions in Phoenix

The recruiter screening & negotiating, then Hiring Manager explanation of the job then Hiring Manager Director who talked about the vision, then the offer came quite abruptly, with a bit of pressure..."here's the offer to you accept now (over the phone)"

I did two phone screens with HR for two different engineering teams. Both of them were very knowledgeable and helpful. However, both times they said they would be setting up an interview with the hiring manager and complete silence thereafter. My advice is to not plan around anticipating the interviews, the phone screens seem to be pointless.
