I interviewed for the Guest Teacher role in November 2018. Interview was conducted first via a brief phone screen and then a longer video chat that lasted about 25 minutes. Questions were pretty standard and the interviewer was very friendly. They offered me the job the same day I took the interview, but I ended up declining due to a multitude of red flags. First of all, they want you to pay for your own background check with a company rather than a police station-and it costs $39.75, which comes out of your own pocket, along with a "processing fee" of $1.28 to CSTN itself. Always be suspicious of an employer that wants you to pay them; I understand wanting to conduct a background check, but they should offer to reimburse you for the costs, not add to them. Additionally, the pay is very low and they refused to negotiate. You're offered ~$85 for one full day of substitute teaching and ~$45 for a half day. Between taxes, transportation costs, the upfront cost of the background check+fees, and food, it isn't nearly enough. They were also a little too pushy about completing the background check; considering I would have been out over $40 for that, they really had no right to be so impatient. All in all, I feel I dodged a bullet with this one and I urge all applicants to truly consider the expenses associated with this job before accepting.

Simple, it was an online interview where you record your answers. It gives 30 seconds of think time for you to craft your answer. It was about 8 questions, the interview is about 15 minutes.
