I told the interviewer thank you, and good fortune anyway.

(I had been expecting this.)

I'm sorry

Next one?

It pays to be polite. If the one they did hire does a bunk on 'em (happened to me) they might come back to you.

marfita: Oh, they were very nice the whole time, sure.

Oh noes! I hope the next one will be the good one for you!

Does't mean you aren't awesome, and perfect for the job. HR processes sometimes steamroll good talent.
