I've been stuck in a pure maintenance cycle for six months, and I'm starting to feel like a script-runner instead of an engineer. I'm trying to move into a senior-level job, and I worry about stagnating, but I'm not sure what to do. Is this a common issue with engineers who hope to level up?

I recently switched to salary, and my workload exploded. Suddenly, everything is "urgent," so I'm working 2–3 hours of unpaid overtime at home every night. The company is billing the client for my extra hours, but I'm not seeing any of it. How do I bring this up with management? I'd rather not keep working for free.

Do you think engineers are better at solving problems or preventing them? I think prevention is harder because success is basically invisible.

What engineering discipline would you recommend new students specialize in (or avoid) given the current/future job market?

I'm a junior engineer, but I inherited a project mid-construction because the designer left. I wasn't around for the early phases, but now I’m running the site meetings. I'm stressed about the technical gap and being asked questions I don't know the answers to. I don't want to appear clueless in front of the clients, even though I am. Is it okay to say that I don't know, but I will get back to them? Or does that look unprofessional?
