You submit an email application to the recruitment email with your CV and cover letter and they get back to you in a couple of weeks to schedule an interview. The interview seem quite different that traditional "interviews", there were no specific questions as such. They explained about the project and then there was silence (no questions asked), since the situation was getting awkward, I jumped in to talk about things and explained my research background and education. At the end, you are asked to submit a writing sample.
