Applied online through University Co-op website; also had to complete an online quiz (about an hour long) composed of pattern finding questions (i.e. a series of number is given, choose what comes next) and simple algebra/logic questions. Interview mostly consisted of behavioral questions (i.e. what would you do in this situation), some brain teasers, and a few technical questions may be asked (especially those listed on your resume and cover letter). Overall, the interview was fairly casual and the interviewer was very friendly.
