Apparently I'm very appointable and very keen so they really liked me but I'm their second choice. He said he's optimistic that another position might come up in the next week or two and if that happens then he'll call me and just offer me the job. So he's optimistic but can't guarantee it. He said that if he calls and I've taken another job then they'll have missed out on me and he'll understand. So back to the drawing board, better start applying for other jobs.
If he were to call and offer me a job then of course I would take it, I need a job and I liked the school. On the other hand I'd feel like I was second best, which obviously I am, and that I was only there to save them going through the interview process again.
