Random or find a roommate for NU 2022?

I am going to NU next year class of 2022 and I am wondering if it is better to do a random roommate selection or to try to find one using facebook. How good is the random selection? Do most freshmen do random? Does it hurt my rooming selection to do random? I want to live on north campus.

My D is a sophomore at NU and this is what worked for her. She expected to do random but actively participated in the FB group and spent some time on there getting to know people. One girl had mutual interests and they agreed to meet up at Wildcat Day, spent some time together and agreed to room together freshman year. It worked out fine and they are still friends altho both live in sororities now.
