Funnily enough, I love a bit of building, but mostly to marvel at how it's done, as opposed to doing it myself. I'm probably better at the demolition side of things, rather than construction :lolol: Love a bit of bricklaying though – that was originally part of my freelance life plan.
I've never had a proper job interview in 24 years of work, so I can't really offer any advice – especially not anything different to what has been said above.
I just wanted to wish you luck for the interview :thumbsup:
