On the recruiting side (I’m not a recruiter but a director making a lot of hires), we actually do the opposite all the time — we post relatively senior positions then downlevel whoever we hire to fit their experience level. A lot of people think more highly of themselves than the employment market does.
We look at the job posting as a brand marketing — all we’re really trying to do is get you to apply and fill the funnel. The whole hiring process is designed to be a calibration on role, cultural fit, compensation, etc.
