When I was making their ads for one of the local newspapers, there were multiple ads every single week for various HC positions, and they always had exhaustive lists of qualification requirements, but never listed salaries. The only places that didn't list salaries/rates (and I'm sure this is still the case) were the companies that weren't competitive.

I was just on a job search between November and February, and I never once even considered applying for jobs that didn't list the salary. It isn't worth the time only to realize that they're offering below market rates.
