Men have the same problem
If I have an interviewee who wants to niggle a lot during the hiring process, I know I'll have to endure the same every 6 months or so when they want more money. Too aggressive knows no gender.
I have found that I like to see a deal/no deal number from a candidate. It simplifies things.
Women (in my experience) consider soft skills as part of their offering. Soft skills don't find their way into job postings, but they are important for the success of the candidate in the position..
I think women could do a better job in articulating this benefit to employers. Maybe they could phrase it in terms of conflict resolution or problem solving.
In other words, it isn't aggressive to sell yourself as a whole person, not just a body of experience on a resume.
