Generating best results for a recruiter for a job description provided


Im using api to generate requirements, boolean search string and a questionnaire from the job description provided.
I’m generating this information to help recruiters.

Im using gpt-4o model and function calling to generate output and parse it into JSON and store in db.

I want to generate technical results. It sometimes gives a bit generic and general terms in my output. I want more technical based.

How can i make it better so that i get the best possible results.
