Signs you are not getting an offer

For context I work in finance (asset management). The work can be high stress so that comes with very dry or cold people working in the field. I have about 5 years of work experience at a competitor. My major is not related to what I’m doing at all. And frankly it is very competitive and my resume is subpar in this industry.

I got a first round interview and initially thought I was unqualified. This would be building off my current experience which is related enough. I completed a hire view answering a few questions. That led to a second round Interview. And did really well there and landed a 4 hour long final round.

I met w 4 individuals, the team lead, the COO, and and both managers (co management id be reporting too) now
