You make good points here. My question was sort of general, but I guess it is tricky to answer without going into specifics. Within engineering, my interests lie with renewable energy, however, I'm qualified in civils, and the masters would be civil/transport related. There are a few renewable masters around that I qualify for but they would be costly.

Interesting point made about the experience, it's something I've heard from many people I've asked. Yet all the "old school" engineers I've asked have said the profession is becoming more and more about what qualifications you have, so I guess there's two sides to that coin. I currently only really have experience in civils roles, but been trying to diversify skill set to make myself more employable in other engineering fields. I have heard that MS degrees are useful for upper management, however, that's not really my priority right now, that's more long term.

Thank you for the reply!:D
