This was a data science take home for a Director level position. Multiple data sets, domain specific, bad/missing data that you had to discover, predictions needed that combine disparate data types together, data is complex enough that off the shelf models wouldn't work, writeup of how to deploy in production, etc. I estimated 10+ hours to do it even half properly and that was probably an underestimate even if you got lucky with your first approach.
