Has anyone ever had an experience where they were positive they had a good chance at the job, but nothing came of it?.
It does happen from time to time. I had an on-site interview that went well. My last interview was with the CEO and founder of the medium-sized company, and he said, "If you've made it this far, you basically have the job." One week later I got rejected via email from a woman in HR I had never met or talked to. Sadly, I'll never know the full story.
