I put all companies without listed salary at the bottom of the pile. No salary listed means the company assumes candidates will see the low pay, and will see nothing else of value in the job, and skip it. Which means the company thinks it doesn't provide competitive value as an employer. Why work for a company that doesn't believe in itself?
