A couple of behavioral questions with small technicalities involved. Interview lasted for around 20-30 mins. They were very responsive and communicative about the whole process. Questions involved my academic background as well as previous experiences and extracurricular activities. You are not expected to know everything about the job you will be assigned to

30 Minute phone behavioral interview, only technical questions asked were about the classes I took and if I liked them/what I learned. Focus on seeing if I'm a fit for the group, not necessarily what I know.
