I've recently found a job that I'm very interested in taking. Most jobs, where I am working, do not list a salary range. They usually will ask your current salary and/or ask for your expected salary. I've already been asked my expected salary, but I delayed the question by saying, that I'd like to know more about the role before I can give that information out, which was gladly accepted at the time.
I did a lot of searching and I saw this position was listed on several different websites with different ranges. The one that I contacted the employer on, had the highest range, which is quite a bit higher than what I am making now, but the other websites' listed salary ranges listed are also still acceptable.
How can I negotiate for the best possible salary and can I use these posted salary ranges as my expected salary range? Can I be direct and say I saw them posted where we contacted and believe this is good?
