My expectations are very much the exact opposite. When a company posts a range, especially a large range, I expect them to at least pretend that the lowest end of the scale is the best they'll give during salary negotiations. Companies, and companies people trying to hire you, have an incentive to get you the worst deal you will agree with.

That said, ranges are still nice to have. I'd much rather have an estimate below expectations than another company saying they offer "competitive wages". Competitive just means "what you earn right now, or worse".
