Applied online and had to complete online tests and video interview. Was then invited for a telephone interview. Was given an option of times and the whole interview was about half an hour. Usual questions about why I applied and why I think I'm suited etc. The lady was very nice and felt more conversational than a usual interview.

First are tests. If you pass, you go through the telephone interview, then the assessment centre. Friendly interviewer who asked relatively easy questions. But make sure you have enough to talk about.
