How much I was expecting to be paid. I always remember that one. Well the first time I was naive and maintained that the hirer knew better, they would decide. I was hired though. The next time I already had a job that paid me relatively well, the interviewer was just about to give me a job that would pay me less with the promise of a raise the following budget year, I told them I was not sure. They never called me back and I did not really care much.
