A video call introduction and just questions about myself. The call was around 30 minutes, Show how your interests align with the job you intend to apply. It should not be hard because you might have taken the class already or know the topic you applied for.

Interview
You have to look for the position in the student employment website. Then send them an email. 99.9% of time they will get back to you(with good or bad news). But at least they get back to you. Half hour interview with the staff. They mostly talk about what you are interested in. You don't have to dress up too formal or formal at all.
