DaVita PCT Position interview questions

I had applied online a week prior, received an email requesting a phone interview at my discretion. Used a calendar link, and selected what works. Interviewer called at scheduled time. This was a preliminary interview, however, it was super positive--not like here's the job and $30/hour positive--but you could feel night and day between DaVita and another international dialysis competitor of theirs. Interviewer had seen my application, saw my experience (I have experience), asked if my certification was current. Explained the position slightly (where it is). Asked me if I had questions, which I felt was odd, but I haven't interviewed much. I know they ask you that question, but he didn't ask me any critical thinking questions before asking me that. I don't know if that was like step 1 of 5, as I've read on here; or was it step 1 & 2 of 5. I'm not sure, but I had interviewed the day before with a dialysis company I previously worked for (left them--main reason was super unprofessional--surprise they still are) and to me, personally, this was a much more positive experience. He told me who would follow up, their name, and their back up if they didn't contact me this week. Told me to call his cell if I don't hear anything by Friday, and did say he'd be OOT and gave me the name of the woman who was covering him on that day. All-in-all, I felt like it was a neutrally positive interview. If they offer me a job, boy, I'm taking it.
