100% wrong.
If I'm building a team, I don't need everyone at the exact same level. I want a mix. I want some juniors, some seniors and a tech lead. The job description is the same, I'm not writing 3 or 4.
Couldn't you have a single job advert with a wide range and in the description say that you're looking for juniors, mid, and seniors and that you'll tell people early on where you think they'd slot in?
Job descriptions for junior positions and tech leads are not the same.
