I sent my application, and received an email invitation to record a video interview. It basically involved going to a website and recording answers to questions presented on the screen. Times allotted for answers ranged from 30 to 90 seconds. You get a trial round, and then 1 chance to redo the interview (same questions for the most part, but in a different order). If the hiring managers like your video interview, you get invited to attend a hiring event, either in person or by phone. I attended mine by phone since I couldn't make it into the city that day. Interview was conversational and casual; they tell you about the job/responsibilities, and ask you about what you're looking for, past experience, etc. One of my interviews went a little more in depth about my knowledge of current political events and economic/economic policy, but it wasn't anything too rough, provided you keep up with the news. After the interviews, I sent over some writing samples; got a call informing me I got the position a few days later.
