Actually, it looks like the winners will just get interviews at Facebook.
I think Kaggle is a very interesting site and company, but I think it's a stretch say they hold "data science" competitions. Most of their contest are extremely limited in scope to applying machine learning to pre-sanitized data sets. This really covers only a small part of what practicing data scientists do.
Highly ranked contestants who indicate their interest will be considered by Facebook for interviews, based on their work in the competition and additional background.
Not much of a prize.
Anyway, this sounds like a great way of candidate hunting, and a refreshing solution to all of the "interviews are broken" posts that have been around lately.
Now it links to Kaggle directly with a title that makes no sense whatsoever and provides absolutely no context. So instead of getting contextual information intended for mass consumption (an article), we got nothing of value. Great job.
