The purpose of this exercise is to give the team at Branch some insight into the way you think, and your style of product design. There's no time limit to complete the exercise.

Branch is thinking about launching a new mechanism that lets the mobile developer have a hosted 'mobile web splash page' for every link that gets shared. An example of this would be if HotelTonight's users shared their Branch referral link publicly, any clicking users who did not have the app would see a splash page, hosted by Branch, that showed the sharing user's profile with some text and call to action to download the app. Clicking the button would then take the user to the app store page to download the app.
They're thinking about making it a set of parameters that can be added to a Branch link on creation, which customize the formatting, text and graphic assets. Please come up with a design for the set of parameters that customize the splash page. For example of some of the other parameters that can be addd to a link, see this API reference.
