Excellency,

As someone who interviews and hires teachers, I personally don't like the demo very much. It's soon obvious how much a teacher knows as the interview progresses, assuming that the person asking the questions is him/herself a qualified teacher. In addition, most teachers can pull out a perfect lesson, the one they have practiced again and again for demos... and which are completely unreflective of their actual teaching skills.

If the person asking the questions doesn't know much about teaching, then the demo is basically used to see if you're okay. In other words, that you have some idea around the classroom, with an activity or two up your sleeve.

When you do the demo, which likely won't last long, explain that you intend to do a brief warm up followed by a quick presentation and drill of the target language. Further explain that you would expand on the drills, monitor, and elicit examples to gauge comprehension before moving onto freer practice. This should get you through the demo fine.

Hope this helps!
