| >How is someone supposed to reasonably negotiate that role? Get a competing job offer. A minimum price lets labor sellers know if it is worth applying or not, and trends in supply and demand for that type of labor (based on which way the minimums are moving industry wide). |
For this reason always try to cluster job interviews together as much as possible so that the offers come out around the same time. This situation is generally going to be very favorable for you as an engineer!
Consider that some hiring manager probably has been played games with for months in terms of head count and interviewing poor candidate after another. When they extend that offer to you, they want you seated yesterday. Mentioning "I have 2 offers, I've had 100% offers for every interview so far, and btw I'm interviewing at a FAANG tomorrow." - that will perk up some interest and can elicit a pro-active better offer.
I've had one outfit ask me, "How much for you to just stop interviewing and come work for us?" This sense of urgency on the employer side is the only time where an engineering employee has more power than the company. Most employers will try everything to make this window of time short - usually by trying to get you to stop interviewing and do no salary negotiation, or give you an exploding offer, or counter and say there are competing candidates.
