Hello, New to the forum and looking for some help! Having successfully completed stage 1 in our migration visa process (Panel Beater), a date has been provided in London for my technical interview. I would be very grateful if anyone could provide me with any specific information regarding this and what I can expect to be asked relating to this profession or anything about the interview process itself. Apologies if this question has been asked before but tried to search without any luck. Thanks roccotime
