Accurate fasteners interview questions

Had some brief communication during some phone tag and emails. Asked Accurate Fasteners what the salary was and they absolutely REFUSED to tell me! Stated, "Those questions are typically answered after the interview process." I tried to let them know that I was looking for a career change and was not looking to make less money. I did not want to waste each other's time. But to no avail. Why is this such a big secret? Ironically, there is a previous post here on Glassdoor, written by a Accurate Fasteners employee, stating how management does not give out raises often enough. This should have raised flags.
