It's basically a weekend of drinking coffee and listening to people talking about flying and instruction. A lot of it is very interactive, with the attendees split into groups and given tasks to perform, which range from simple things like putting ticks in boxes, right through to organising a short presentation.
I attended one of these not because it was required, but because the school I did my FIC training with run the seminars. On the weekend of the seminar I couldn't do any training because all my instructors were lecturing at the seminar, so they invited me to attend for free. I found it interesting and educational - probably not something I'd necessarilly choose to do again, but it's not something to worry or get stressed about either.
