I haven't tested the link, but I'm familiar with similar products. You don't seem to know what exactly goes behind screening CVs.

To get structured data, it's not just about parsing the file (PDF, Docs) with an open source to get the text. You need to extract skills, qualifications, work history ... etc.

There are tools already doing this part very well (before LLMs), so you need to make multiple LLM calls to make the right match or provide useful information.

Your comment suggests that you think it: Hey ChatGPT, this is my CV, and this is the job description; review it and give me suggestions.

Building systems around LLMs is not that easy.
