I've heard a few times that if you don't hear anything regarding your last teaching interview within 3 days it's unlikely you'll get the job. On one post on this site, it seems posters got some indication they were being hired immediately. The last time I was hired for a teaching job I heard from HR the next morning that I was recommended for a teaching position and that they needed to conduct a background check. The time before when I was hired at a Private school, I wasn't asked questions but rather was hired on the spot due to a recommendation. What are your thoughts??
