Data Science Take-Home Challenge

The Data Science Challenge is the second stage. You will receive a data science take-home challenge from Airbnb. The take-home task or challenge has a 'to be completed and submitted' clock time of 24 to 48 hours.

Data analysis is the take-home analytics task. You must analyze a dataset and create a PowerPoint presentation using the results. In three hours, candidates for the data scientist algorithm position must complete a take-home task from Airbnb. Specifically, test data findings, create a straightforward predictive model, and justify the model selection.

  • Given a set of Airbnb data, analyze it to recommend 2-3 product changes to grow bookings.
