Embodiments provide techniques for presenting a user interface. An initial interface containing a first plurality of selectable elements is presented to a user. Embodiments assign the user to a first one of a plurality of preference groups. A plurality of selections made by the user of selectable elements from the plurality of selectable elements are detected. Embodiments then generate a second interface for the user that includes a second plurality of selectable elements, based on the first preference group to which the user is assigned and the selectable elements selected by the user.
