Applied online. After they read my application, they called me for a phone interview which just asked me basic questions about myself, my education, my experience, my availability. Also discussed pay rate. They told me at the end of the phone call that they'd like to set up a Skype interview for the next week. Before the Skype interview, I had to complete a series of exams to prove my competency. You only get one chance at each test. The Skype interview comprised of a discussion about the company, a discussion of subjects I'd like to tutor and gave me time to ask any questions. They also role played with me acting as the tutor and presented a few questions and asked me to teach it as if I was working with a real student. Found out at the end of the interview that they would be offering me a position.
