Hi kev
I'm in a similar position as you, I will be taking the Metal Fabricator technical interview in a month or so, I too am looking to find out type of questions asked etc as nervous about it like you are. I have an agent doing my visa for me recommended from a friend who now lives in Oz. Apparently the interview is very chilled out and layed back, more chatting than anything. Questions to start with are about the training and things you had to do, first learnt, then goes onto health and safety, ppe etc I've read this on other sites and it's the same as my agent has said, they have sat in on numerous interviews as someone has to be in the room with you so there's no cheating, looking at books, phone etc.
I really wanted to do the practical but have been told that could take ages on a waiting list due to not enough assessors, so the interview is what I will have to do, my fingers are crossed it all goes well. I'm a welder fabricator of over 20 years, it just means so much to me and my family to get this interview right. I have completed the Ielts English test so just need to do the interview, then health check and police check, I should have the visa granted by august apparently, I hope so !!
If you find out anything let me know could you
Many thanks
Danny
