The interview process was simple and not stressful. I started with a brief self-introduction, including my major and relevant courses. The interviewer asked why I wanted to apply for the TA role and whether I had experience helping other students. We also discussed my schedule and responsibilities as a TA. The interview felt friendly and conversational.

It is fairly very straight forward. You need to simply show your intentions of working as a TA with your resume, you are mostly liked to get a TA in one of your top three preferences of roles/courses.
