A lot of candidates assume job listing advertisements are an org chart. In reality, job listings (at scaling companies especially) are a lead generation tool to attract desired talent into a hiring pipeline.what does that mean? if you are hiring you describe the qualifications that you are looking for. if you have a range of qualifications, you say so. if it is not a specific job, then don't describe it as such. i'd happily apply to a listing that doesn't advertise a specific role as long as my qualifications match.
if candidates come to the wrong conclusion, then maybe the job description was not clear about that.
i can see the problem with a broad listing that could be a match for anyone from junior and up, but we are talking about changing laws, so this could be taken into account.
