Helen Keller International interview questions

Completed the first round which was a somewhat casual, "confirming the responsibilities of the job" interview with someone in HR. This included going through the responsibilities, verifying my experience, and asking if I had any questions about the role itself. I was told the next steps would be two additional interviews with the Development team and a "task"/assignment. When asked what my desired pay would be (the range for the position states the pay range is $53,000 - $74,667), I was flat out told they usually only hire at the median range ($64,000) and weren't particularly willing to budge on that. I struggle to understand why they would provide a range at all given this information. The interviewer did not seem prepared and it didn't seem he fully understood the role -- he was flipping through different open roles at the organization because he was having difficulty finding the correct job description to read from.
