True - there is no flexibility but that's kind of the point. The situation you describe is exactly how salary discrepencies and potential gender inequality happen.
Realistically if you have a candidate you want to hire but they are not happy with what the algorithm spits out either your baseline isn't correct for the current market situation (and therefore should be adjusted, affecting every employee), or it's not the right candidate.
The algorithm should be an accurate representation of what your company is willing to pay for an individual at a certain level.
If the candidate is not happy, fine. Can't have everything and they may be overvaluing their skillset. If the company is not happy, a single candidate should not get preferential treatment over the other employees.
