Definitely not for all companies let alone all positions.

You can get it from similarly positioned positions. For a simple example, you can google average starting salaries for your major. You can submit your resume to AI and ask it what your salary should be. You can go to a recruiter, who makes money by getting you as high a salary as possible (and they do know their business and their clients).

I've been on both sides of the negotiating table. The idea that the employer dictates terms is not reality.
