I had a phone interview first which was pretty basic. The second interview was in person and I had to come prepared with a skill to teach the interviewee. It just needed to be pretty basic, so I taught him how to tape a hockey stick. I've heard others who have instructed how to play a chord on the guitar or even a dance move. It was pretty fun. Then they said that they would ask me to teach a random driving skill that they would give me. I had a few minutes to think about it, and then taught the interviewer, in my case, how to change lanes.
