It’s pretty rare in our field for someone to be able to land one job offer but not a second one.
Sure, there are a lot of applicants banging away hopelessly (because they’re not qualified and those people should not negotiate), but most everyone else in software who can land job offer N can land job offer N+1 without undue difficulty.
IMO, SWEs have never had more “walk away” power since I joined the field about 3 decades years ago.
