Where I come from, we don't expect noob engineers to invent game-changing new products in their first few months out of school. Why? Because unless you've spent a little while in business, at least working for someone else, you're simply not going to know which market niches are starving for a better mousetrap.
So, sure, I'm only six months into working in industry but I can already name a fair handful of things that could use improvement through healthy market competition or improved engineering techniques. But I've been working for an R&D company for six months!
Ex nihilo creativity doesn't work and isn't a valid thing to demand from people.
