It’s more complicated than that. You’re an engineer with a certain degree of experience and the recruiter will have an idea of how much that’s worth when they start the conversation with you, so they know up front how much money they stand to make as a ballpark figure, and how much work is worth putting into getting you an offer. Once they get you to the offer stage, and most of the work is done, they want to close the deal as soon as possible for as much money as possible. They know the band for the position so, if you’re lowballing your ask, they have every incentive to bump that up. On the flip side, if you’re asking for something on the top end of the range, and it looks like a long negotiation, they’re looking to spend a lot of incremental time for not a lot of incremental money, so it’s better to get you to accept an offer - any offer.
