There were seven rooms for the interviews, so I assume there were panels in each of them.
My interview went pretty good. Totally tripped all over myself when a really specific question on how to explain the difference between the subject and object of a sentence came out of nowhere, but after all my humming and hawing I think I salvaged a semi sensical answer :/
Were someone to ask me that at any other time I could easily give an answer. In the middle of an interview that was entirely "why do you like Japan?" up till that point my brain had a total meltdown. Good times!
It was also fairly lucky that I showed up to the venue two hours before my scheduled time slot. The letter I was sent out had the wrong time and I had to go in an hour earlier than previously advised!
