Had to apply online first. General information, and a few broad essay questions that focus on diversity, problem solving, etc. If you do well with that (and there is no reason you shouldn't), plus you have a 3.0+ GPA, you get to the interview. The interview questions are behavioral in nature, dealing with conflict mediation, diversity, stress, etc. After that, you have the RA class. It used to be that one would be hired after the class; now you will be hired before.
