The way I have seen this addressed, in a way that seems fair and forthright to me as an applicant, is to create titles with job descriptions and requirements and minimum salaries for those titles, and advertise that you are looking to fill a position with one of the titles. Tell the applicant which title(s) they are interviewing for, and you both have a much better idea of what to expect.
