We gets tons of resumes from candidates in our job portal https://jobs.fairshare.tech/. We request candidates to appropriately choose the skills in our portal's profile. But we know they will not do this as diligently as they should. So we set up a Python batch job to read every new and changed resume and using NLP extract all the IT skills and update their profile automatically.
In our websites watch portal we use NLP to capture spelling mistake. Watch below video to see its use.
It helps our system do auto matching and suggest candidates as per job description.
