JFR Visa - interviewer coming to my home

What’s up guys. Been in Taiwan for well over a year now.

Finally was able to submit our JFRV application yesterday. We were told it’s customary for them to come to our home for an interview. We can be called at anytime during the next two months and both me and the lady have to be available to talk to them.

Any heads up on what kind of questions they will ask?
and also are they pretty brutal on looks?
I’m a nice guy but I have long hair and a beard (or perma stubble if I shave) - I definitely don’t match Taiwans idea of a nice well adjusted gentleman.
