There will be 3 interviewers asking you a series of tech-related questions, as well as situation based questions. You do not have to be extremely tech savvy, just have good people skills. They are able to train you to do a lot of the tasks that will be needed of you.

I was interviewed by 3 other people. The first half was behavioural questions. For this portion expect "Tell us about yourself" ,etc. The second half was technical questions. They told me at the beginning they do not have any expectations for this section and that it is OK to say you don't know. If you took CSE 247 take a look at your notes because will help you for that part.
