Thanks for the excerpt.
a so-called CNC machine
Really? Framing it "so-called" makes it sound esoteric and rare, while in fact it's an utterly common machine tool used in many industries to create ... pretty much anything (eg. casting dies for Lego bricks). I wish they'd tone down the alarmism (unless they know it's ordered by "Ivan's Shell Mfg. Co").
Isn't that the norm? Like the old joke about hell seeming to be an all-out vacation, and then it turns out that was just the marketing brochure?
I very recently landed a sweet-sounding well-paying job at a large international consulting house. Turns out, on the inside it's all gaffer tape and leaky abstractions. Not some of it, all of it. After having spent a few months sussing out the scope of the issues I determined that yes, this is unfixable by any one new hire, so I've done some interviews and will be starting a new position elsewhere presently.
