Girls Who Code Summer Immersion Program Instructor interview questions

I was interviewed online. The interviewer was a past instructor and was very friendly. Interview was composed of mostly behavioral questions. At the end one technical question was asked which involved finding logical errors in a code snippet

Google Hangouts interview. Interviewer was nice and professional. The organization emailed me one technical question to prepare to teacher to a student having trouble. I role-played the situation as the instructor and the interviewer was the student. There was also one surprise technical question in a readable language that they did not tell me about to see how I would respond to it.
