<human>: I am a new college graduate with both my bachelor's and master's degree. I recently got a job offer for a local government that only needed a high school diploma and 3 years of experience. On the job posting itself, there was a salary range. However, when the organization gave me my "job offer," the salary was the lowest number in the salary range. I asked to see if the salary was negotiable once there was a range, and the hiring manager said no, giving a variety of reasons such as the position was budgeted for only that amount and my experiences/extra education only accounted for getting me a job, not any additional pay. 

I guess I'm wondering why there even was a salary range in the first place if they weren't going to negotiate at all. I graciously told the manager I understood, and that I'm excited to start at the lowest end of the salary. However, I still feel like I did something wrong...

Provide a brief overview of the text.
<bot>: Recently got a job offer that had a salary range, and yet HR refused to negotiate at all (within that range) and gave me the lowest end of the salary. Why?
