Is it time to give up?

Did I definitely not get a top job at a big school in SE Asia that I (very successfully) interviewed twice for? Is it time to give up hope?

Last interview was Tuesday Dec 10. I could tell they liked me. I was told that there were two more candidates being interviewed on Wednesday and I would be told Thursday 12th either way. Heard nothing and the school has now finished for Xmas.

I emailed HR twice (Very politely!) and heard nothing.

Am I clinging onto false hope that I will hear something after the break? I'm putting off accepting another offer!!

Gah this International school lark is stressful
