I submitted a Google form that included the courses I was interested in tutoring and had to answer a couple of short response questions. To be qualified to tutor a course, a instructor has to provide a recommendation. After the submission of my application I received a confirmation but had to wait until the recommendation was submitted before being offered an interview. The interview was straight forward and I had the option of having it in person or through Skype since this was before the school year had started. There were three Graduate Assistants but they were all very nice and made me feel very comfortable.
