After you submit your application, if you make it through the first round you are invited for the interview. I scheduled a Skype interview because I was out of the country at the time. The connect was bad on their end, so only my video was on, but the interviewer's was off. The interviewer was late to beginning to session, and there was quite a bit of background noise. Didn't seem to be the most professional way to conduct an interview. Otherwise, she was really nice, asked a few questions about my skills, background, interests, why SEO etc..
