ELI5: Why do employers (usually) not explicitly state what the hourly wage of a position will be preceding the interview process?
gpt
because they advertise it too low then some people wouldn't bother applying.  and if they advertise it too high then some people wouldn't bother applying.  

so they don't advertise it at all and so you come in and interview and they ask you what your pay history is and try to make the lowest offer they think you'll accept.
