I don't really get this

I haven't been writing much here of the past week and a half as I've been applying for jobs and also going on interviews.

I had the first interview yesterday and it went very well.

"We'd like to offer you the job...I think you'll be very happy here and I'm pleased you'll start in September"

"Well I have another school to speak to first but I'm really pleased about this"

And the after about five minutes they decided to withdraw the offer. I explained I made a commitment to both schools.

They said it showed a lack of commitment.

A lack of commitment to a school I didn't even work for? What?

The arrogance was incredible, they waved the fact they got a decent ofsted inspection in my face and expected me to change my whole professional life for them. What other industry wouldn't even give a candidate 24 hours to decide on a position.

I saw a much better place today.
