Questions About Hiring Processes

I recently went through the interview process for a position and had a great experience. I initially had one interview that went well, and then I was referred to another role where I had two interviews, the final one being with the director. I received positive feedback from recruiting, indicating that I’m a top candidate and should be hearing back soon.

However, I noticed that the same position was posted again last week, and now I have three applications for the same title. Is this a common occurrence? Can anyone explain why a role I applied for has been reposted like new? If I were a recruiter, how would I interpret this situation? Is this considered normal in hiring practices?
