They asked my salary range, what should I say? (Detroit)

I do not know whether to give a range or ask for theirs. I am in Detroit, in case local advice matters. I looked up ranges in Detroit and they vary a lot.

Check several sources for pay in Detroit, then pick a range where the low end is one you can live with.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
