MSCA experience and job hunting

I would like to share with you a few thoughts about the programme and future career expectations. It is true that an MSCA programme is quite prestigious and sought after by many candidates and institutions alike. It offers a PhD, a great pay and industry placements. I was personally very lucky to be in such a position and work on a very industry relevant topic I have now concluded my time as an MSCA ESR and faced with the dilemma of staying in academia or going to the industry. Due to the nature of both the MSCA and the project I joined, I am particularly excited about the latter . However, the industry doesn't seem to think likewise. I was turned down from a position today because of the salary. When asked, I mentioned that my expectations were 40-45K gross. Its seems a lot for a first job but then again I am an Electrical and Computer Engineer who was studying for his Diploma for 6 years + 3.5 years of PhD. So I am offended if in their mind I am compared against an engineer who comes out of school of 3 years study. 9.5 years now and I still cannot consider myself an engineer, still learning and probably will for the rest of my life. What stroke me the most was the fact that they took the choice of joining or not due to limited compensation out of my hands. They didn't say "we can offer this much", they said "you are too expensive for as". I understand that these are difficult times we live in, but then again accountants are offered way too much for what they produce. At the end of the day, I still am an engineer, I still provide solutions for products where everyone else would fail (and by everyone I mean people who follow the common path) and look towards maximizing the company's profit (as this is what an engineer does, provides the best solution from a techno-economical point of view). Maybe in the UK they don't have quite the same definition of an engineer like the rest of the world, as I've seen people declaring being an engineer but not following the same style of studies as in my country. For example, as an electrical and electronics engineer I have a broad knowledge of the different stages from designing a transistor, to forming gates and amplifiers, to logic units, to processors, to low level machine language, up to high level OS structures. I believe to be a "jack of all trades and master of none" and that is exactly what this company was looking for. I'm not the best violinist, but I if he's sick I am his best replacement, or the pianist's, or ever the conductor's. This is how I see an engineer from a music event's perspective. Somebody might say that I don't have industrial experience for such a salary. At this point I wonder how much "industry related" is MSCA, when it is advertised as such but not considered like that from the industry itself. Did we get false hopes when we signed for it? Or is it an issue with the industry that just sees PhD and assumes I am another over-glorified graduate, fresh out of campus? Your thoughts on this, if you please.
