Illinois Public Health interview questions

There is a four part interview process based on what was shared with me at the first screening interview. Screening interview, panel interview, interview with potential supervisor, and interview with leadership after a verbal offer is given. The screening and panel interviews were fine for me, I then received an email communication that I was no longer being considered. A few months later I got an email saying "next steps in your application" and asked me for a third interview the next day. I took it and asked for clarification in professional terms since I figured a conversation face to face is better than delayed emails. The supervisor assured me I was one of their top three choices and apologized that there was a mistake with the rejection email. I probably was at the bottom of their list and the other candidates withdrew is my guess. After that interview I was ghosted and no one responded to any of my communications. The interviewers didn't seem prepared, disorganized, and they didn't answer the questions I had for them very well. One of them answered about a completely different position that the one I was applying for too. Timeline: I applied in August, screening in Oct., panel in late Nov., then third interview in Feb.
