Me? I can't tell you how it works, I could guess. But in terms of the experience, it just serves you up jobs. Seems pretty good at it though. Probably using some sort of AI NLP stuff as I get the best matches over any other one for remote consulting type work which isn't as easy to come by. I actually wrote one of those recruiting tools by scraping stack and github and used nlp with some deep linking logic stuff with neo4j. They didn't do anything with it though.
