They remained firm that they couldn't budge on salary even a little. Then remained firm as I asked for a signing bonus (denied) and reduced hours (denied). This company doesn't do stock at all and they've already got unlimited PTO so no room to negotiate there.
Meanwhile, their interview feedback indicated I did very well. They unanimously wanted me, and I slightly exceeded their technical expectations for the role.
Seems tougher than I remember from before covid.
(Throwaway since I don't want this tied to my name for my current or future employer to find.)
