Hello! A friend of mine last year was interviewed for CSUSM and her advice to me was be VERY prepared. Know basic speech anatomy, phonetics etc, and be prepared to be tested on this. What they are really looked for though is your interpersonal skills, so just do your best, take a deep breath and smile. Schools choose to interview applicants with the requirements they are looking for, they just want to know you before being accepted into their cohort.
