Holberton School AR/VR Programs Software Engineer/Education Facilitator interview questions

I did a phone intro call, an interview with another facilitator, a building tour with another interview in person, and a technical interview with an education facilitator. Everything was great up until the technical interview. I was told that the interview would cover the type of material on the syllabi for the program. I downloaded the catalog and studied through the topics in the syllabus to freshen up on the items listed- AR/VR work in Unity game engine, and C#. The Technical interview did not address any Unity work and the questions were not in C#. I felt as though I did ok- I was just really rusty since I have only used C# and focused on game dev in recent years. It concerns me that they are looking for an educator for a specific topic but the technical interview does not even address that topic. Perhaps my understanding of how this coding school works is off base.
