I agree that reading job ads can be helpful, leading to a better understanding of various companies, teams and positions.
That said, it can be dangerous to believe whatever is on the job description.
Because many job ads are written by recruiters (agents) who have very little clue what hiring managers (principals) are really looking for from a candidate.
The work experience requirement section on many job postings are grossly inflated – and the experience inflation has been growing steadily over the years.
I would not be surprised that in 5 years, a recent graduate will need “minimum 3+ years of work experience” to land their first full-time job.
The solution for job seekers you asked?
In the short term, provided that you have a solid resume, an effective (not elegant I agree) solution is to 10X the number of jobs you apply.
