It was a 2 part process. The first is a webcam prerecorded interview. You answer about 5 questions via webcam- each timed for about 2 minutes. The second round was a skype interview with the supervisor of the department you were interviewing for.

I was first sent a link that with instructions on how to take the video interview. During the interview, I had to record my responses to five questions. And for each questions you get 30 seconds to prepare, and then one to two minute to respond.
