I would simply say "yes", I do expect one, and if you don't pay me, I will not show up
. Actually, I've always maintained that I was "negotiable" (to the recruiter types), but once the position is "secured", and the offer has been extended, it's usually been "OK by me". IMO, don't eliminate yourself "early in the game" by a "number"...if they really want you, they will pay you what you're worth (or more)
!
ps: One can always decline their first offer...I have.
