How can you talk about salary if you don't know the job ? I certainly won't negociate the same money for a start up, a big co, a remote work, a borring one, one with hard challenges, one with long hours, one with benefits, location, travelling, fancy clients, bonuses, shared values, etc. After a first call, I won't know remotly what I need to know what to negociate for, and giving any price is most probably setting wrong expectations that will be very hard to come back from later. It seems lose-lose to me. Besides, i have several offers at the same time. I put my recruiters in competition.
