Yeah, I fully agree. I had mine in 2013.
The interview (more of a chat) was conducted on a Skype kind of set up.
The guy interviewing me was very relaxed and easy to get along with. The conversation began with health and safety questions, and how you go about preparing, and approaching a job.
There were a few questions about welding gas mixtures, and as previously mentioned, the coloured tungstens uses.
There was one thing in particular, that I think made the guy know, that I know what I'm talking about, which was.... Has asked me to describe a marking out process, to form a shape.
I even impressed myself, with my answer..... I talked him through, step by step, exactly how to mark out a 'square to round'.
To be fair, I'm sure that those who know how to do this, will admit, it isn't easy to explain to someone, who isn't stood in front of you, without being able to draw any kind of diagram, exactly how to do this.
at this point, i felt that he was no longer sniffing me out, and was more interested in where I'd worked, and what I'd built over the years.
if you know what you're doing, have a bit of technical knowledge to back it up, then you'll be fine.
Good Luck mate. Let us know how you get on
