The problem is that many job descriptions are too vague for me to be able to decide if I will be a good fit. The story I’d like to be able to tell is I did X at company X, I can do X+delta at company Y but your job description doesn’t give me any information about the thing you want me to accomplish. Simply put, it’s not a description of the job, it’s a description of your HR filters.

I’m not going to write a cover letter about how good of a fit I am for your job if you don’t give me enough information to understand what your job is. Most job descriptions are 90% useless. What I need to know is, what is the problem you need me to solve, and what resources will I have to solve it. If you as a recruiter do not know that, you’re not the right person to write a job description.
