Filled out application, and was invited to do the online interview. You are asked to answer two questions, and then you have to teach two problems and record yourself. The application is a bit tricky, and they only give you two tries per question. The first question I didn't realize they had sent me the problems ahead of time so I just stared at the screen, waiting for the question to pop up. Ended up okay--I used a chalkboard I have in my room to demonstrate what I was teaching. They're really big on the "ask as many questions as possible" thing, so make sure to pretend you have an audience and ask questions such as "what's the first step you would take?" or "how did you get to that answer billy?". Next I was invited to a Skype interview with a woman that took about ten minutes. We pretty much just talked over my resume. Last interview was also Skype, and I had to teach problems (they give you ahead of time) to the interviewer. She was really nice, and pretty much said this part of the interview is just to make sure you're not incompetent. I was given an offer via Skype.
