Can you try teaching at your local university meanwhile?

EDIT: The reason I ask, this is something I wouldn't mind doing but I've never really considered due to a lack of credentials.

Not sure if I'm misreading, but are you saying interview was cut short / you had an interview lined up that just got pulled at the last minute? If that's the case -- don't worry about it. This is like organizational maturity level of 0, I had this happen exactly once in my early career and it screwed me up for a little bit. So if that's what happened and I didn't just misread -- don't spend any time taking it to heart.
