In my chapter, around the 3rd week of pledgeship, the Pledgemaster, gives the pledges and Brothers who wish to be bigs a questionnaire to fill out on what their interests are and what qualities they would like in a big/little. Then, the Pledgemaster uses compatability though said questionnaires to match the bigs and littles. Usually, he sends the pledges on a day-long scavenger hunt that leads up to finding out who their big Brother is.
