I don't know for sure, but I think it was only good for an interview. There wasn't any kind of legally binding language in the contest rules, and the fact that I received a ping from Facebook recruiters despite finishing past 50th place in the competition makes me feel like it was a fishing expedition. It's money well spent for Facebook when you consider that they probably aren't paying more than 50k to Kaggle to host the competition and probably get at least two hires out of each one.
