Applied at major hospital for bioinformatics position

I recently had a positive onsite interview for a bioinformatics position at a major hospital in NYC. During the interview, I met with eight faculty members, including the department chair, and the conversations felt very collaborative. Some of the faculty even spoke in terms of 'when you start' rather than 'if,' which made me feel optimistic. However, it's been about two weeks since the interview, and I've received no updates. I sent a polite follow-up to HR a week ago and reached out to the hiring manager two days ago, but still no response. Before the onsite, they were very responsive, so this sudden silence is puzzling. I'm starting to wonder if I'm being ghosted or if this is just typical for academic hiring processes. I appreciate any insights on whether this kind of delay is normal.
