In Spotify's onboarding, the user picks artists and podcasts that he likes to customize the navigation when he arrives in the core pages of the product. It's interesting to note that each picks actualize the other suggested picks. If you pick a rapper, Spotify will suggest other rappers. The more data Spotify collects, the better the experience for the user.

In Wattpad's onboarding, the user will select up to 3 genres that he likes to read. These preferences will be used to suggest content when the user arrives in the navigation of the app.
